260 rem results

Well I finally got a good chance to shoot my 260 build that I did off the 110 action with a 24” E.R.Shaw barrel.
Loaded up 18 rounds all shot at 100 yards
3 with 44.0gr of H4831sc and 130 gr Nosler Accu-bond (NAB) seated @2.978 = a 2.5” group
3 with 44.5 gr of H4831sc and 130 NAB same seated depth = 2” group
3 with 45.0 gr of H4831sc and 130 NAB same depth= 1.95” group

3 with 43.0gr of IMR 4350 and 130 NAB same depth =1.25” group *********
3 with 44.0gr of IMR 4350 and 130 NAB same depth = 1.50” group

3 with 40.0 gr of RL 15 and a 120 nolser balstic tip seated to 2.975 = a 1.75” group

also there was a decent wind today id say no more than 20 mph gusts

was this with a sporter or varmint barrel? Just wondering what I may be able to expect from mine.

sporter im thinking. its a standard savage replacment barrel.

I don't know anything about Shaw barrels or the 130gr Accubond but 2.97" OAL seems awfully long to me for a bullet with a tangent (standard) ogive vs. the "narrower" secant VLD style ogive.

For comparison's sake, in my Criterion 260 barrel 2.95" OAL touches the lands with the 130 Berger VLD, 2.90" OAL with the 140 A-Max, and 2.87" with the 130 Norma Golden.

boiler you are correct my COAL is 2.798 and 2.795. brain going faster than fingers or maybe teh other way round. but i asure you im under the 2.800. which is what all my books say and my mag measures at.

I'm familiar with that ;D

You say your magazine will only let you load to 2.80"? That stinks...

maybe a tiny bit longer but not much when i ordered the new mag well and follower i messed up and ordered one for a SA not a LA forgetting what i was working with.

im wanting a SSS fluted bolt body so if i tear the bolt apart i might order the longer mag well.
so i might be asking for help on a bolt disassembly and reassembly in the future.

anybody tryed RL 22 in the 260rem?????????????????

Yes, 44 grains at the lands 2800fps and no signs of pressure using 243 brass.

stangfish thanks what weight bullet?

Sorry, 140 grain Nosler AB's and Speer Deep Curl hunting bullets. I had good luck jamming the lands. Tight group and same POI both bullets but some heaavy recoil. I figured I was overpressuring but no signs. To be honest I think my next loads will be 42 grains and work around that.

Cooker900,
I might have the same barrel as you and have just purchased a second one..Mine is the 24" E.R. Shaw stainless 1:9 that Midway offers as a kit screwed in a 110 LA....I also have a long action Shilen barreled .260 also in a 110...After this next Stevens build there will be three LA .260s in the safe...

I tried 4 different bullets and only two powders during load development including 123 gr Scenars, 123 gr Amax, 129 gr SSTs and 130 gr. VLDs pushed by H4831sc or IMR 4350....Lots of good results in both rifles except for the 129 gr SSTs (quit trying before the box was empty.. I mean bad).

I have had good luck with 130 Bergers at 2.915 (about .020 off) coal and 123 Amax at 2.815 (again about .020 off) coal the Bergers love 44.4 grains of H4831 SC at 2775 and the Amax like 43 grs. of IMR 4350 at 2925....Both bullets shoot under 1/2 MOA out to 400+ yards and both still shoot under 3/4 minutes at 600 yards....although I have only shot them at 600 on two trips to the range....I found it best to limit the groups to three with the Shaw as they start to spread as the barrel warms...I have a 100 yard range at home so most of the development was done here....

The Shaw barrel started cleaning well in less than 100 rounds but now has about 500 down the tube after load development...I hope I learned a little and the new one shoots better right out of the box (ha-ha)....

Mine are mounted on a long actions (as the new one will be) but yours might accept the 2.815 COAL of the Amax or something close to that...The Amax bullets are relatively cheap and shoot real well (several one ragged hole groups at 100)...The Amax is not a hunting bullet but did the trick on a 200 lb muley in WY for me this year at 310+ yds never got out of its bed.
The same gun found a couple of 8 pt. whitetails in MN & WI with the 130 Bergers all DRT....

I didn't try the Bergers much deeper because they shot well at .020 and .015 and I didn't want to give up much more powder capacity....But in my Douglas barreled 25-06 I found that 115 Bergers shot the best at between .040 & .100 off the lands...It is possible you may be able to sink them in deep enough to fit in your magazine and still shoot well....

I tried the 129 Hornady SSTs and could not get them to shoot in either the Shaw nor the 26" varmint Shilen with either powder at any distance from the lands jammed or jumped....It seems that some barrels may not like a certain bullet/powder combination and maybe that is the case with your ACBs....

By comparison the 1:8 Shilen also likes the 130 Bergers at the same COAL as the Shaw (only the throat is a hair shorter in the Shilen, so they are about .015 off the lands)....It also will shoot the Amax load real nice.

These were my first .260s and it took a while to find what they like but the persistence paid off in the end..
Good luck with yours and keep us posted...I am starting my next build with a Stevens and the Shaw in the next couple of weeks and might be asking your help when I start working up a load for it...

Good Shooting,
Randy

wow thnaks guys

yes mine was theh kit from midway.
and ill help out if i can like you so far my best results are with the IMR 4350. the main reason i ask about the RL 22 is that is the last slow powder i i have so i figured why not try it.

and i am only doing 3 shots as well just because thats all i have ever done.

H-4350 works good, rl 17, superformance with 130 vld 3050 out of 26 encore shaw barrel.

I've had best accuracy and consistancy with H4350 when compared to H4831 and other powders in a 260 20" 1:8 twist Savage factory barrel, or 22" 1:9 twist Shaw barrel. The 130 gr Berger's and Accubonds shot best with H4350. The same was observed with Sierra 140 gr GK's and H4350. RL19 showed real promise with 120 gr Nosler BT's, 125 gr Partitions and 120 gr Sierra PRO Hunters. But I ran out of RL-19 before I got to 130 and 140 gr bullets. I've settled on H4350 and 130 gr Bergers @ 0.010" off lands as a hunting load for my 20" Savage LWH in 260.

Based on what I have observed and read, It seems H4350, a Hodgen Extreme Powder is hard to beat in a 260. Never tried RL-22 or H414 which are the other powders most often metioned with H4831 as working well with the 260. Finally found a home for the bottle of RL-17 in my 6.5x284 with 140 gr Bergers.

i think i found something that has real promise. 46.5 of H4831sc

Shot my new model 12 LRP 260 REM. With my encore load. One hole with 4 shots. 140 A-max moly, 44.0 H-4350 fed 210, oal 2.810 sorry no crono yet. Shot 2800 in encore. I have found hard to beat H 4350 in 260.

that is my next and last to try until the weather breaks here in PA. i for the most part am happy right now in case i decide to go coyote hunting. will get it tighter in the spring

Cooker900,

not to get off topic, but what part of PA are you from ? I live in Mercer county. Just curious when I see someone on this site from my home state.

zap currently i live in hershey

but i was born an rasied in venango county.

I also bought the .260 Rem barrel kit from Midway. But mounted mine on a short action. I haven't had much time to work with it yet, but found H4831 worked well with it. My bullets of choice for it at the time was 140gr Sierra GK. These bullets shoot awesome in my Ruger M77 Mk II with a happy load of H4831. I haven't found a great load for the kit barrel yet but have found several that brought in respectable 1.5" or less groups at 100 yds. I have found that this barrel is a bit rough inside and does copper foul fairly quickly. Hopefully this will smooth out fairly soon and do better as my load development with it progresses. As an aside, also picked up an A&B 25-06 barrel at Midway while they where closing them out. I am very happy with it as well and can get 1" or less groups with it fairly easily with both H4350 or H4831.

got my load
120gr nosler ballistic tip
46.5gr H4831sc

how are you resting your gun when shooting these 1 inch and larger groups are you shooting off hand a 260 should be shooting 1/2 moa or less at 100 and 200 yards, a 260 off a poor rest should be at least 1 inch at 100 yards for 5 shots, a buddy of mine had ER Shaw put a barrel on his 270 and hes not happy at all, I no nothing about ER shaw barrels, but my factory savage model 12 in 260 is .3 and 4 moa to 200 so far

for the 1" groups a caldwel zero max

for the .5 bags of cat litter

if I think about it later I will try to post my target from last time out a wk ao and if I can figure out how to upload picture on here. you should think about learning to bed your stock it is very easy to do, even just bedding recoil lug will help a bunch, go to brownells and but some arcaglass in the gel easier mixing 1 to 1 and spreads nice it come with release agent, then buy a box of clay from there also or you can use play doe, spread realese agent with a cotton swap (Q Tip) all over barrel , and put a piece of masking tape on front of recoil lug and trim excess off, spread release agent on rest of recoil lug and back over the first action screw, put tape and release agent on the stock in front of recoil lug, all that release agent should go half way up the action area just a little past half way , just past were your action sets above stock, fill action hole with clay on the stock and on the action or you can use you action screws but dip them in release agent now now fill the hole where the recoil lug goes in 3/4 way up with your mixture of arcaglass, use c- clamp or action screws and snug action down in stock the acraglass will ozze out the top maybe, so line the top of your stock with tape also, let it cure 10 hours or better, if done right you will need to hit the bottom of barrel on the arm of a sofa or something soft and stable to get it apart, if you did real good youll have to really give several good wacks, and it will come out, now you will have least amount of movement from shot to shot, some serious competition shooters just permently glue their action in the stock for good, assureing no movement, once you feel comfortable you can do the rest of the gun, to do action screw area all the way back you have to take out trigger that easy also, there are video's on line that can help but i have never seen one that really does it well for a new person to understand.
