New 6.5cm, 26'' barrel, 140gr Nosler rdf. What should I get for powder, that isn't h4350?
I couldn't find any 4350 either, so I've been loading Sierra 142 SMK's over IMR4451 and having good results in a friend's RPR.
Thanks for the reply. I was just at Cabelas, no 4350 h100v rel16 rel17... They did have 4451, should have grabbed it.
IMR 4895 if you can not get the gun to shoot with this it aint going to shoot. I have found loads from 22 hornet to 7mm rem. mag with little to no problems.
It may not be the fastest or the cleanest but it works and after all what counts more SPEED or ACCURACY.
I spun on a 6.5 CM, EABCO barrel several weeks ago, and made the choice to NOT use H4350 for my load development due to lack of availability. I went with RL-17 instead. Works well enough, though I have not completed load development yet. RL-16 is also supposed to be a good choice, slightly better velocity, but also getting a bit hard to find.
I have used IMR4451 in place of H4350 in 22-250 loads, and I found it to be a suitable replacement. It seems a bit pricy though, or maybe I just didn't shop around enough.
imr4451 or RL15 would be my choices. I gave the 140RDF 300 opportunities to shoot well. Never knew if I would have a .5" gun or 1.5" gun. I only know 3 guys that are shooting them reliably and they all happen to shoot AIAX or AXMC Accuracy International Rifles. The RDF is extremely jump sensitive and it's something you have to keep up on constantly. This is why I sucked it up and shoot the 140 Hybrid.
I actually started with IMR4064, because it was what I had on hand, but after reading some other's experience, I made the trip to get a slower powder. I don't know what it is, something to do with the bore and bearing surface, blah, blah, blah, but all the accuracy shooters are using what I consider very slow powders in the 4350 range.Quote:

I read they like a pretty large jump, hopefully it will work out.Quote:

My RAP is in a chassis, so I'm stuck at mag length OAL. RDF's shoot just as well in that rifle as my long action in Creed, so I'll disagree about being sensitive to jump.
RL-17 is a progressive burning powder that is very stable in the Creed. Supr is a VERY progressive powder, that also excels especially when heat soak could be a concern. I'm pretty unabashed about being things made in the USA, so I went with Superformance. Never been hard to find online or locally, and is typically really cheap compared to all the other popular powders. Last 16# I bought was for $135/ 8# jugs.
When I had my 6.5CM, couldn't find H4350. Was recommended to try RL-17. Worked very well. After finding H4350, worked up loads. Found that RL-17 worked better for me. Rifle was a Savage 10T. Have heard RL-16 works even better but didn't get a chance to try it out.
My most accurate 143 ELDX load is with Superformance and .085 jump. .00 leade for my barrel is with a coal of 2.935 so my load coal is 2.850. Velocity is 2750 with 1/2'' groups out of a 24'' barrel. IMR 4350 and W760 were the other powders I tried with 4350 being next best. H4350 would be a good bet from all the data I've seen.
Finally shot some Imr4451. Watch out, it might hit you with its cane as it takes the retirement bus to the target. Max charge of 41.1gr and a Nosler custom comp bullet went a blazing 2556 fps. The barrel only has 60 rounds down it, it might pick up 300fps. Oops too many zeros. It did put down a pretty decent group of six shots...for having a powder variance of 1.4 grains. Batteries died in the chronograph before we could test off the shelf winchester 125gr. Maybe next time.
Never thought of using 4895. What are charge min & max and what are you seeing velocity wise? I'm not a speed freak, but fps has to be decent.Quote:

Before I found some H4350 I tried SuperF , IMR4350, W760 with 140gr and heavier 4064 with 95 SST W760 with 129 SST. I worked up some decent loads with IMR 4350 and W 760 but do not like SuperF. The 95 shoots real good and the 129 is very good. With the heavies try to find H 4350 as its the best. On the 6.5 site reloaders are liking R 16/17, 4451 and 100V after H 4350 in that order. The market is currently pumping up with H 4350 and I picked up #8 a month ago and am shooting ragged holes.
Not to hijack original post, but I'd be interested in your data with the 129s. Welcome to PM the info if you don't want to post openly and all precautions duly taken.Quote:

I however have not experienced such, but have not shot in temps below 30 degrees. From what I am reading RL16 may be the real deal. I plan to try it out this weekend if time permits. However I am in SE Missouri and it was 1 degree this morning, but will be 50 degrees or so this weekend when I shoot. With that said I wont be able to report about it's cold weather speed. But you know what, I'm glad,lol......
PhilC glad to share my data. I am still working with this bullet but am out currently. My best load is 44.5 gr W760 coal 2.680 crimped in the grove. Vel. 2912 ES 19 sd 6 and a 5 rnd. group measuring 1/2'' out of a 24'' barrel. The only other powder tried was IMR 4350 with poor results.Quote:

Change is inevitable; though seldom welcome.
I'm gonna go slightly off topic but still related and worth pondering over if you're bored...
One thing to note about Hybrid-100V is it's "Heat of Explosion" rating is much colder than most other powders and should extend barrel life compared to H-4350.
Problem I have is H-4350 Heat of explosion values are contradicting from a couple of sources... My QL version 3.6 shows H-4350 at 3,760, ADI-2209 (H-4350 in Australia) according to QL has a value of 4,000. And According to the Barrel life calculator, H-4350 has a value of 3,990.
So the calculator shows the following....
.264"
41 gr of powder
58,000 PSI
H-4350 with value of 3,990 = 1,932 shots before accuracy starts to drop off.
H-4350 with a value of 3,760 = 2,600 shots
Hybrid-100V Heat of explosion value of 3,545 = 3,490 shots
Zero333 I'm not surprised by those 2 different factors. Makes sense with an up to 10% difference between lots of powder. I've seen plenty of guys go to 3000-3300rds before accuracy dropped off hard in both 6.5 Creedmoor and 6.5x47 and it wasn't truly accuracy dropping off, just more unpredictable fliers than usual.
I really like H100V in the 243 with 105s & 107s. In 15" of barrel the barrel stays clean and the muzzle brake doesn't turn instantly black like with some powder, actually it stays pretty clean in my opinion. I'll use it in the CM when I start loading for it.Quote:

I was at Scheels a couple weeks ago and they had 8 pounders of H4350 for 199. I'm sticking with Hybrid since trying it.
I put some Reloader 15 in mine behind a Nosler 120BT. 1st 10 rounds down range (1 is a low sighter out of the pic):
