Reply With QuoteGreat shooting. The arrow might be good but the Indian is too.
well i decided to swap my barrel out before the match season starts as i wasnt sure if the old barrel would make through with almost 2900 rounds through it and i didnt want to get caught in the middle of the season swapping barrels and working up new loads...i should of waited as this was just to easy LOL!!
ill skip the riffle pic as it looks just like it did before the swap...28" shilen select match i got from Jim last march besides its whats on the inside that matters right!?! the new barrel came from shilen and i sent in 6 dummys to chamber it to so that 142g SMKs,139g lapuas and 140g hornadys would seat with just the boat tail in the case touching the lands...in other words a LOT of free bore. i went out this morning despite the 20+MPH winds(because i was like a kid at Christmas)mostly to fire form the new fully prep'd lapua brass. i did a light break in...fire 1 clean for 5 rounds then fire 5 and clean Xs 2 and started shooting as both 5 round groups took 5 patches to remove all copper. now for the good stuff....
first up is the difference in free bore...left is a 140g hornady seated touching the lands in the old barrel...right is a 140g hornady touching the lands in the new barrel...free bore gain from old barrel to new barrel is .128"
keep in mind when looking at these groups the wind is blowing 20+mph from 10 o'clock to about 12 o'clock of shooter and im trying to hold for wind(something i need to work on)....
gotta love 100V in a 260
like i said
Great shooting. The arrow might be good but the Indian is too.
28" lenght barrel Dave?

yes sir...according to shilen its their tactical chamber...supposed to be a little tighter and shilen doesnt have a tight neck in 260 but the tac chamber is .296 compared to their standard which is .297...im going to have PTG make me a reamed for the next barrel with a little tighter chamber and a .294 neck.Originally Posted by eddiesindian
i also went out yesterday and fire formed the other 50pcs of brass i had prepd and things didnt go so well. all the groups opened up with the largest being 2" and the smallest about 1"...after 15 rounds i was like WTF? i pulled the scope and checked base screws...all good...checked action screws SEVERAL times...all good...i then started playing with torque tuning and nothing changed. on saturday i couldnt set up my chrony because of the winds...yesterday was nice early but was calling for high winds again later so i had a chance to chrony some loads and needless to say they were all over the place...one group round 1 was 2837 and round 3 was 2927 and the rest were all in between. i had 10 rounds left and was sitting there waiting for the barrel to cool with a 100 things going through my mind as to what could be going on...fouled barrel?...the wind the day before blowing the bullets into the same hole(or REAL close)every time LOL!! well i grabbed 2 of the last 10 and started looking at them still thinking WTF is going on here?? then it came to me like a slap in the face...not one piece of brass had collet marks on them from the lee collet die!!
i felt like a dumbass!! i was in such a hurry to beat the wind i forgot these cases needed to be neck sized.when i got home i read the sticky note i wrote and stuck on top of the box...FULLY PREPED NEED TO NECK SIZE!! the neck turning expander leaves the necks at .291 to .291.5 outside measurement after turning...the loaded neck size is .292...the cases on saturday were .289.5 to .290 after running through the LCD.
like i said i really feel like a dumbass and i wore my flame suit today because i know when yobuck reads this ill never live this one down LOL!!!

I played hell with the wind yesterday as well. I was sending them out to 1000 and found myself having to hold upwards of 7moa for windage. I hit 7 out of 12 so all was not lost. I decided to quit after I saw the wind flags start shifting directions. The flags were flying full out in only one direction 1st thing in the morning but started shifting later durng the day.
Glad you found your mistake.
Take a chill pill Dave......the accuracy monsters will be there next time.
LOLOLOLOLO

We shot 1070 yesterday in a full value wind that was at least 10-12 mph. 2.1 mils of wind on a Creedmoor. Was good practice. :)
i was holding 3 to 3.5moa at 205yds for wind...like i said it was blowing here saturday...friday there was 92mph winds in the foothills around here and a good 60+ in town and it just kept blowing right through saturday.
3 moa @ 200?......wow......
Hard for me to do.....but wind at that velocity "forces" me to quit while Im ahead.
Sure it may be good for practice......but in the end?...it becomes more of a guessing game at the expense of my wallet.
now if I had somebody supplying the components for my addiction?.....well hell............thats a different story..loololloo

Your one of the few guys on here that i can have some fun with lol.
But probably the wind did blow them in rather than out.
Hey how much for a roof just labor. shingles are in my garage as are the rusty nails.
Pitch dont mater right? i got some guy with wet clothes will do it for $15 hr. can you match that?
Do you charge to remove the old ones?
My chamber is on the small side of .296
Nice shootin!
Good to see the BTHP's are workin for ya, now you gotta try the Berger Hybrids!
TRUST ME!!!
I have two Shilen barrels an am extremely happy with both, next will be a 28"
For $15 bucks an hour you better jump on that!! But make sure hes a roofer.
My labor would be $100 per square up to 6n12 and goes up $50 bucks an inch past that...the $100per would include tear off...i wont roof over old shingles it looks like sh!t after a summer and the chance of blow off is high...i like you but dont want to be married to your roof lol!!
Can you post a few of you charges and velocities? Or PM me....im asking because im thinking this is another fast barrel...ill know for sure saturday and ill post.
I had my neck tenison issue last sunday but most every 43g 100v load i clocked was 2895+...most were over 2900.
In winter temps 43.9 of H4350 and 140 bthp's with coal of about 2.835 gets 2797 and 2830 at summer temps.
That load has no issues baking in the sun at 100+.
24.8 of H4350 and 140 hybrid @ 2.875 gets me 2840 at 35 degrees, not heat proven but I'm thinkin it will be ok.
Win 243 brass on both.
I wouldn't call mine l a fast barrel, but pretty normal.
I never could get above 42.5 in the heat without blowing primers and wrecking brass with the Nosler brass.
Speed wer about 20-30 below you in a 26" barrel.
Mine were loaded to fit AICS mags.
im going to revisit the H4350 load i posted this weekend as it looks very accurate and will post speeds but im pretty sure at 44g its right at 2900 which would be about right if your shooting a 26" barrel.
the 24.8 must be a typo? i think you meant 44.8g? ive got plenty of room left and could probably go up to 45.5g of 4350 before compressing...ill have to check my COAL but off the ogive 2.395 is touching the lands with the 140g hornadys...i have to retrain myself to load rounds...im use to grabbing them by the bullet and dropping them in now i have to grab them by the case and drop them in bullet first or the head hits the bolt head and sticks in the lug slot on the right side and they kinda jam.
Yea, typo
44.8, by the appearance of brass and primer I could go further.
Out of curiosity how far did the lands move back in the life of your old barrel?
.007 I think...I'll look and let you know later or in the morning...it wasn't much compared to my 300 barrel...about 1100 through the fractory 300 and lost .015.
Steel...i just checked and i lost .008 in my old shilen barrel from new to 2800ish rounds.
well i went out this morning to confirm loads and it didnt go like id hoped...first i cleaned the barrel and shouldnt have as it took 10 rounds to start shooting again...42.5g of 100v was no where near the speed i thought but was accurate...the pulled shots was all me as i had a few millers friday night...
now this is interesting...i figured this load was about 2830-2860fps...im very happy with the speed and pretty sure less millers and seating depth will tighten this group up..i shot two groups with this load and both were the same as far group and FPS...
also forget to say that the above groups were shot with .004 neck tension...i backed my die off to .002 as thats where ive had my best results at.
Again just joking.
I figured lol
well i went out today and shot 50 rounds and was on my game but the results are pretty sad to say the least...i had this barrel chambered to shoot slower powders but got caught up in barrel life and round count. now we all know that slower burning powders burn hotter than faster powders so inturn slower powders will burn a barrel out faster but a barrel is a consumable just like powder,primers and brass so at this point im no longer concerned with barrel life and next weekend will start load development with the powders i had this barrel chambered for..H4831sc..IMR7828ssc and norma MRP...the norma MRP and IMR7828...according to quick load...shows the best velocities,lowest pressures and best barrel life as 99.7% of the charge is burnt in the barrel with MPR and 100% with the 7828...H4831sc shows 98.37% burnt in the barrel but i had great accuracy with it but couldnt get enough if the cases with my old barrel. now for those of you not familiar with all these numbers this is how your most accurate loads will break down in any riffle...IN THEORY...100 to 101% full case and 100% powder burnt in barrel will produce the most accurate and consistent loads and longest barrel life. ill try some RL-17 as well but it only shows about 93% full at max loads but ive had great results with it as well plus i have 7lbs of it.
now im not sure why but the first 54 rounds of 100V and H4350 shot nice tight groups but now not so great...even with different primers and torque settings on the rear screw...like i said maybe the wind blowing them into the same hole LOL....
all the other groups i shot today were worse than these and not even worth posting.
ok this was a long weekend lol. saturday i went out twice...i shot norma MRP, RL-22,and H4831sc...the second time out i shot the best of these powders with different primers to see if i could get a handle on the wild ES's with the RL-22 and MRP and to fine tune the H4831sc...primers didnt help much with the RL-22 or the MRP but i was shooting them pretty fast so ill drop the charges and play with both a little more....this was the first time out and the worst spread was RL-22 but the MRP was about the same speeds but 58FPS...the second time out the best was with a fed210 primer but was still 40FPS...
now sunday was one of the worst days EVER...first time out 730am...i get out to my spot and get all set up to shoot grab my ammo out of my bag and as i go to set the box on my mat the lid caught on my coat pocket and my ammo dumped every where...now this wouldnt of been a problem but i had loaded up a 10 rounds with RL-17 and BR-2s and 20 rounds with H4831sc at different seating depths...10 were with BR-2s and 10 with fed 210s.
second time out...915am....i get all set up and am REAL careful setting my ammo down on my mat and every things going good...round 1...3075FPS WTF!!! i thought something wrong with my chrony?? so i check everything and fire round 2...3070FPS...then it hits me like a kick in the nutz...this is H4530 NOT H4831sc...my wife was vacuuming when i left the first time and moved my powders around but its my fault for not looking before dumping it in the hopper....i did shoot 3 more rounds as it wasnt showing any of the typical pressure signs other than flat primers but im pretty sure the primer pockets are opened up on those 5pcs...now the funny thing is those 5 rounds were the best ES ive EVER had...round 3-3072FPS..round 4-3073FPS..round-5 3072FPS...to bad this is WAY WAY to hot!!! needless to say i pulled the rest of these apart.
3rd time out 1pm...well this was a bad day that ended well....
140g hornady
.006 off lands
.003 neck tension
fully prepd lapua brass
46.3g H4831sc
fed210 ES 20FPS or BR-2 21FPS they both shoot about the same with a slight edge going to the fed210 by 1FPS
2834-2854FPS...i will tighten this up a little next weekend...i think i can get this in the single digits with a few tricks
4th time out to verify load...2pm...5 rounds 330yds...this group was a little bit tighter the 3rd time out but the wind was blowing and i was pretty burnt out after going out 6 times in a weekend....
ill also play around a little more with the MRP and will also try some RL-17 when i get a chance.
