Do you think a 1-13.5 twist barrel would stabilize a 70 or 80 gr bullet?

Looking at a rifle in the classifieds 6x45 with a 1 in 13.5 twist, only had 58 gr bullets shot thru it, I have a ton of 70 and 80, 85 gr slugs and a few 60 gr . Hate to have to buy another weight bullet just to scratch a itch.

Maybe the 70s but I wouldn’t expect much accuracy out of the 80s or 85s.

Not copper monos. 1-7, 1-6.5 range.

It won't work for any 80's I've seen. Yes, up to about 70, though. I've shot several 70gr sierras from a 13.5 and a boat load of 74 Bergers, when they made those. in both 13.5 and 14 twists. But a 13.5 won't work with any 80 I know of, by quite a bit. It's by far mostly about bullet length.

Thanks, that was what I was thinking, 70, maybe 75 gr.

Is this for match or hunting?
I had a 1:14 barrel for a 250 savage. It shot up to 100 gr lead-core bullets acceptably for hunting.

I got a 13.5 that's not done yet. Iv been following this thread. I picked up some 75s yesterday just because. I had read on some older threads people claiming some success. But it wasn't with 4 grove barrel if I remember right.

It’s all about length. With a flat base hollow point you’d probably be good up to 75gr. Boattail tipped bullets are a different story.
