.260 rem barrel

[Rem6br]

anyone using the gain twist barrels with .260 Remington?

 

[Someoldguy]

I've a .260 Rem, 1 in 8, but not a gain twist.

Shoots less than stellar. By quite a lot.

Switching cartridges based on this experience.

How about yourself?

Have Two 260 barrels (one currently installed), both shoot great. Nothing wrong with the cartridge. It’s not good a pushing 140-142gr bullets fast, does best at 120-130gr.

What twist? I've tried going lighter than 140s. Maybe my barrel is just not up to the task . . . (?)

I'm doing just fine with 140s and 147s. I'm pushing 140gr hybrids at 2900 fps and the hornady 147s at 2800 fps using imr 4451. I've heard of people pushing them faster with rl-26. Brass does not appear to be taking a beating either. Several reloads and the primer pockets are still good (lapua). Barrel is an 8 twist.

I built two 260's this past year. Both were 1-in-9 twist and are hunting rifles. They shoot the 140 grain bullets pretty good at 100 yards in spite of the recommendation of 1-in-8 twist for that weight. Probably wont do too good at 400 and out, but drop deer in their tracks closer. It's funny, they both shoot the 140's better, group wise, at 100 than the 120's. Haven't tried any 130's yet.

 

[Someoldguy]

Mine shoots 1 1/4" @ 100 yds for a 10 shot group. Will hold just over 2 1/2" @300 yds. 42 grains of H4350. Once again, a 10 shot group.

But I expected better than this from a premium barrel.

I have been thinking about a build on a .260 rem. Was just wondering if the gain twist barrels are worth a try.

I bought a gain twist barrel about 5 years ago from one of the premium barrel manufacturers for a 6 dasher. It is a light varmint contour 28" tube and it shoots pretty nicely but I later bought a used 6 dasher with a heavy varmint contour one inch longer and straight 8 twist that out shoots the gain twist barrel.
I guess going forward I wouldn't shy away from a gain twist but I wouldn't go to extra expense to get one either. Just my humble opinion.

Bullets automatically spin faster every inch they go through fixed twist barrels. They're accelerating all the time.

What advantage is there to a 5 degree rifling angle to bullet axis entering the throat change to 6, 7, 8 or 9 degrees altering the grooves' width and shape in the bullet before it leaves the barrel?

Bartlien Barrels says the gain twist rifling is always putting a "fresh bite" on the bullet as it goes down the bore of the barrel. Where does the displaced jacket metal go? Is it uniform around the bullet?

So does a fixed twist, for the most part, because bullets' accelerate as they go through barrels. One side of the groove in bullet jacket bears harder against the side of a rifling land as its speed increases.

m I killed two Mule deer and a nice Whitetailo buck last year with my 260. I shoot 100grain Noslers Bt

I really like my .260. My standard load is a 129 Interlock at 3000 fps, but I loaded some 147 ELDM at 2825 and it shot 1/2 moa and smucked an antelope just fine. The .260 is great, but I have to say, I like my cm a bit better, due to a better magazine fit. I don't know why anyone would want a gain-twist barrel for anything, as long as you can get a quality 1:8.

My .260 shoots anything I put in it except the Berger 130. In all honesty I didn't spend much time with the 130. It will however shoot 123, 139's and 142 very well. I have killed numerous deer with a 123 scenar, plenty of blood and a nice silver dollar exit.

to accomplish what?

Hunting/target rig no matter the purpose just wanted to know if there was any gain in accuracy with a gain twist barrel vs the standard twist.

 

[VaRandy]

Don't know of anyone claiming better accuracy BECAUSE of a gain twist over a standard twist. If you took the exact same load out of each it would teach you nothing because of course you need to start all over again working up your best load so I don't know how you could have definitive proof.Gain twist defers some initial shock for a heavy load and gains you RPM which might allow the bullet to remain supersonic longer (or not). We have enough variables now to deal with.
