53 gr or 62 gr TSX bullets

I have two ARs, one with a 1/8.5 twist and one with a 1/9 twist.

Which bullet would be best for hunting deer? I have a boat load of 40-64 powder. Is that a decent powder for these?

Thanks for replies. Just wanted to know if anyone has and results of either.

I bought some extra 55 gr TSX's and loaded up a hundred more with CFE-223 powder, they are only running a little over 3K in my 7 twist 16" barreled carbine, hoping they will work on deer sized game, haven't used to other bullets you speak of.

The only reason to use a 53 gr TSX over the 62 gr. version is if your rifle won't stabilize the 62 gr. Version. Your AR's should. .

62 TSX and TAC

I shot 4064 with 80s many years ago. Accurate, low SD and ES. But slow. Could not get a ton of speed from em.

Barnes theory is go one lighter than you normally would, I've had good luck with other 75ish... and I load 62 tsx, but alas I've yet to shoot anything with them. I've always had 75 bthps in the mags so far when something is around that needs shooting.

Perosnaly I wouldn't hesitate either way. There isn't enough weight difference there to make much difference.

Now in my 6.8 spc necked to 6mm, I run 85 tsx because the heavier ones would be to slow for my taste in that round.

I would go with a 55's (or the 50's if you can find them). The research I have done suggests that you do not need to go heavy with the TSX, especially at the sacrifice of velocity. There is no real harm in it, but no real need. The 50's (might be available only from Black Hills, I'm not sure) and 55's expand and penetrate in gel and through barriers as good as anything. Also, they are longer than an equivalent weight cup and core, so you may run into stabilization issues sooner than you would with a conventional projectile.

I reload, but I have a lot of 4064 powder I use with 308 and 3006. So 55 or 53 TSX going fast would kill better than a heavier one going slower.

Lighter is better with Barnes. I would use a 40gr TTSX if they made one.

40 TSX for deer? Kind of light, unless it is so fast it penetrates and explodes deep.
