.223 Remington twist question

[nhassey48]

I am wanting to shoot 75g AMAXs for 600 yards. I also want to be able to shoot 55g Ballistic tips for varmint. Will a 1:9 twist overstabalize a 55g?

My 8 twist will shoot 52 gr pretty well.
I'd say the 55 will work in a 9.

You should be more concerned about understabilizing a 75. A 1:7 wont "overstabilize" or tear apart a 55gr 99.9% of the time

Yeah that 55 will run just fine. My barrel didnt like them, meaning I got junk groups compared to the heavier ones, but they shot. My 9 twist runs the 69s and 70s really well, but not so much anything more than that.

I have a 16" HB 1:8 on an AR platform that shoots everything from the 40 vmax to the 77 SMK well. The 40's even group into 3/4" at 100 yds. The 77's shoot into 1/2".

Re: .223 Remington twist question

1-9 won’t over-stabilize 55's however 1-9 may not stabilize 75 a-max. In my Remington tactical it would not work, but I can run 75-77 BTHP's fine. Others have said they could shoot 75 a-max's so I may just have a slightly slower 1-9 twist from Remington or temperature and altitude may have come into play.

I have found Berger 70 VLD’s to be great for my tactical. BC of the 77class run at 69class speed. Coyote’s don’t care much for it though…

My 1:9 seems to love 60gr V-max's.

I have a 1-9 26" PSS and it shoots 55gr ok but loves 80grs.

We're in the process of figuring out what my son's Rem. 700 with a 1 in 9 likes...
So far, 52 gr Noslers and 63 gr. Sierra SMP's are at the top of the list. Anything heavier is all over the paper.

Every gun is different...
