just because a certain bullet has a high (number) ballistic coefficient, dose not mean the bullet is built for what you are doing. An exampple would be some match bullets that are made for paper targets out at about 500 yards. Work great, and hold nice tight groups, but not all that great for large sized game. This is specially trued with some of the sub 30 caliber bullets due to construction alone. I've long said that bullet construction is the single most overlooked (or flatly ignored) thing in shooting. Just because said bullet has enough power to get the job done at 400 yards dosn't mean it will stay together at 400 yards. A fine example here is bullets you might use on elk. One bullet has the 500 yards you want, and has a nice high B/C number. Yet it's really a bullet designed to punch paper with. Right beside that bullet in the charts are two others that are about 15% lower in the B/C factor, but these bullets are built like an Abrams tank. They will break the shoulder bone of a bull elk with ease, while the other will like break up shortly after entering the body. Still there are a few manufacturers that do make some fairly high B/C hunting bullets.
In a 22-250, you probably are not going after anything heavier than 40lb. That being the issue most all good 50 thru 55 grain bullets will work quite well. I personally like to use the heaviest bullet that will work with the twist in my rounds that use big cases (even a 22-250 is in there). That way I can take as much advantage of the case capacity as possible. Another fine example is the 6mm Remington. A great all around case design, but I honestly thing it's at it's best with 85 grain and heavier bullets (I wish we had a 130 grain bullet). One of these days (before I finally get put in the ground), I'm going to build a 1:8 twist 22-250 improved off a .243 case length (about 2.00" overall length) to see if I can seriously shoot those 75 thru 90 grain bullets that are out there. Right now we are all faced with either a 1:14 twist or a 1:12 twist unless we special order in a 1:9 twist Savage. I don't know if the 1:9 will handle 75 grain bullets, and I'd really like to start with 80 grain bullets. The idea here is to have a legit 550 to 600 yard ground hog gun without going into excessive over bore condition. This is one reason why I like the 6/250 combo so well. With the right twist it will shoot further than I really have any business doing.
