260 rem

My 260s always had a particular liking to the 139 Lapua Scenar. That and the 140 Amax. The Lapua was the best performing bullet. It liked 46.5 grains of H4831sc for 2860fps. This was over a decade ago so I'm guessing some of the RL powders would outperform and maybe even be as accurate.
260 really likes the H4831 and the sc. The RL powders are pretty temp sensitive.

RL16 and RL23 are temperature stable.
 
I haven’t used shooters world long shot powder before. The 130’s are on the light end of bullet weight I would be willing to try.

I hope you return safe and sound!
If their BC holds up to what Sierra advertises and I can push them fast enough, they should keep up with the 142's all the way out to 1200.

I will have to look into it. I never thought about running that light of a bullet.
 
I do not know if Nosler custom comp makes a heavy 6.5. but Ringo is right I shoot the Nosler custom comp123 in my stock DPMS ar10 and have shoot some very small groups with it.
260 rem AR10.. nice! That will be my next 260 rem purchase.
 
I am looking at testing a new bullet this year in my 260 rem rifles. I’m testing for combination of reasons. I’m bored and have time to kill. Also would like to test out a “cheaper” bullet. Would just like to have another option for a bullet.
I am currently running 142gr SMK.
I have a Savage 12 LRP 260 rem with 1900 rounds through it and a
F Class Savage custom 260 rem with a 30” Shilen barrel with 700 rounds through it.
I shoot out 1200 yards, but I am not a competition shooter. Both rifles have 1/8 twist.
Powders I have on hand IMR 4350 H4350 H4831 and H4831sc.
Do you guys have any other recommendations for a bullet?
Lapua 123 Scenar, Fed. 210M, Starline Brass, H4831-SC around 43.5gr. - It's a magical combination!

I never had a problem with temperature sensitivity. I usually shoot early spring fall and winter so temps are pretty much the same as they are when I hunt. I don't compete year-round so I don't have seem to have that problem
 
In my 6.5-284 I used 140 Hornaday Amax when I first got it. I tried Sierra 142 also the Sierra 140 and it shot smaller groups with the Amax. I got better groups from IMR 4831 than H4831.
 
Wish I had thought of that. I had no idea they were going away. Mine shoots Berger 140s and JLKs but they are not priced like the old Amaxs.
 
Have any of you 260 guys used Win 760 in a 260 Rem?

I have used it in my .260. It didn't produce the consistency I was looking for either in group size or SD. I used it in several combinations: Mag. primer, reg. primer, 123 gr. Lapua, Sierra, ELD, 140 gr. Nosler, Berger. I had a good supply of it, so I really wanted it to work, but - it wouldn't. A buddy of mine told me "when you're done screwing around with that, let me know - I'll give you some 4831-SC to try." He was right.
