Tripod, I agree with some of your ballistics information here, I however don't agree with your statement that says that they far exceed the .204. First and foremost, it of course becomes complicated when we start talking about all of the possible bullet/powder combinations. I do all of my personal shooting with the 32gr sierra. But if you know who Greg Tannel is, (he is THE expert of the .20 cals), he has published 4,400 fps with a 33gr V-max, sub 1/4" groups at 100yds. So my point is, if there is no budget/time limit, of course this stuff can be pushed to the limit. Here is the thing... to get your 4,337fps with your 22-250 AI, you are at 78,000 psi pressure, and max limit is 65,000. You are literally loading that case to the top with powder. Yes you are achieving the 4,337 with .8" groups, but at a HUGE price. For one, you probably won't be reloading those cases.. they are going to be cashed! Two, your throat and barrel are going to be burned out very quickly, and three, you are doing this with a benchrest quality gun. I am shooting consistent 1/4" groups at 100 yds at 4,150, I can reload my brass 5 or 6 times minimum, my throat and barrel will last forever, and the gun I am doing this with is a Remington model 700 with a light barrel (probably a 50 dollar barrel). See what I am saying? And if I really wanted to compete with the 22-250, I would load 39 grainers, move them at 4,100 fps AND do everything the 22-250 can do even out at long range! Sorry if I rambled.. haha.. this stuff is very interesting to me and fun.
