The question is will my 1 in 9 twist stabilize the 70 grain bergers in my .223? I have a new SPS tactical .223 and it has the fast twist barrel, I know it will stablilize up to 69 grain bullets but I was wondering if the 70 grain berger might be too long? I haven't shot the rifle yet so I haven't been able to work up any loads yet. Another question is I was wondering what kind of reasonable stock could I replace the flimsy houge with? I was thinking about contacting remington to see if i could purchase from them the compact tactical stock, made by B&C. I want to keep the rifle relatively light weight. Any help would be greatly appreciated.
