.223 1 in 8 twist question

My present 1 in 9" remy shoots well with 50g Vmax and with 73g match bullets, but looking to replace barrel or rifle at sometime in the future (not to soon I hope).
Will 1 in 8" be ok with 50gVmax bullets ?
 
I had an RRA AR15 predator pursuit 20" bbl. with 1/8" twist and my hunting/target/varmint load was a 50g vmax and it put all those into 500"-.600" @ 100. It was a great p-dog gun. I had no issues with the light bullet in it out to 300 yards.
 
We have had great luck even with 40gr. v-maxes out of out 24" RRA varminters. This is not an anomoly as several rifles have done this. It seems as though a 1-8" bbl is a great choice for all your shooting with an AR. 80gr SMK's for F-class, and 40 to 55gr v-max or (ballistic tip) bullets for varmint hunting and plinking. Call White Oak Arms for a replacement barrel, you won't be disappointed.

If it a 30 ins barrel a 1.8 wil shoot a 90g out 1000yds with the right power. ;)

not any 90 currently on the market. Absolute minimum 1-7.5", better still 1-7" rifling twist. To use the 90s successfully at long ranges, the chamber must have enough freebore to run these very long bullets seated well out giving COALs around the 2.7" mark. 1-8" sees even the shortest 90, the Sierra MK, throw 2-3-MOA 100yd groups and produce oval holes at 2,600 fps.
 
+1 for Laurie's comments on the 90 grain bullets. Several guys with the new Savage .223 F-TR rifle have tries the 90's, only one made the 90 grain bullets shoot good. The others quit, very disappointed that the 1-7" wouldn't shoot them.

I shoot a 1:8 twist and mostly shoot 50gr speer TNT bullets. I know some shooters who shoot 52gr match bullets from a 1:6.5 twist. You should be fine.
 
I'm not sure what level of accuracy you're looking for.
My 8 twist 1/8 223AI shoots the 52 AMAX .5-1moa at 300 yards with fire forming loads, depending on wind.
 
one overlooked advantage of a fast twist shooting light bullets is the tremendous rpms generated by the fast twist. a varmint bullet spinning that fast really comes apart in the varmint. an exit wound, especially if small, means a lot of energy went out the other side of the ghog, etc. no exit means ALL the kinetic energy from the bullet was dumped inside the varmint. i shoot a lot of fast twist guns pushing light bullets and have noted the entry wound margins will often be charred, sort of crispy. the fast spinning bullet is very hot and actually "cooks" the edges. muzzel velocity is slightly less in a fast twist as compared to a slower one but the end result is worth it. also, some light weight varmint bullets may spin apart if pushed to fast. i had some berger 60 and 64 22 cal varmint ones come apart in a 1in 8 tw 22-250. [/quote] if i can see you, i can touch you. BANG!
 
lpreddick That is very true. It also means if you miss the bullet almost always comes apart and does not make it much farther.
