[QUOTE="CleanShot, post: 1103576, member: 70364"] Quite honestly my fear of lead is mostly for the sake of my daughter but I'm glad at least someone on a hunting forum doesn't think I'm crazy for worrying about it. Most responses I get are more along the lines of "I've been eating lead for years and I'm fine". I have a factory Savage barrel on both rifles so I believe the twist on the 243 is a slow 1:9.25. I'll try the AMax out and see how they go. What's kept me away from RL22 has been reports of it being temperature sensitive and largely varying from lot to lot. That's what got me looking into the Hodgdon extreme powders. If I practice in NJ in the summer and hunt in NY in the winter we can easily be talking 80-90 degree temperature differences. As far as barrel longevity, I just found out that the 243 has a poor barrel life about two weeks ago and this is the first I heard the 7RM does too. I picked them because they are relatively flat shooting, are considered fairly light recoil for the job, and factory ammo can usually be found for them in an average shop. But honestly I'm new to firearms so what do I know really. I'm not sure what would have been better choices to cover most North American game at long distance without extraordinary amounts of recoil and yet have long barrel life. For now I will have to live with my choices and research a better cartridge for future purchases. [/QUOTE]
