Re: 243 Advice
If you're getting MOA with factory ammo now, you will probably get better with handloads. Should be able to keep that accuracy to at least 400yds, maybe 500. I feel that the 19.25" barrel will be a detriment when trying to go long range with the .243. You will loose velocity with that short barrel and your bullets trajectory will suffer, IMO.
The ammo you listed is for general hunting and should be able to carry you easily to 400yds for deer. With their low BC's, they are not designed for LR hunting. JohnnyK.
