I have used the following brass in my .300: Remington, Norma, Hornady and RWS. The RWS is about the most robust, although the capacity is somewhat lower due to that. The Hornady is about the least, as it seems somewhat soft. I’ve concentrated on using the Norma for the 225eld and the RP for the 208amax/ELDm. I shoulder bump with a Forster collet die and also run them thru the Willis die after every 2 loads. So far so good. There are a few threads in the reloading sections on the 208 and 225 if you want some more info. I drive the 225s a little harder than the 208s, but neither is ridiculous. I find that the little additional performance isn’t worth the wear and tear on the gun, or the brass. In the end...what are you getting...maybe a few less drop past 1000yds?? Anyhow, that’s my opinion anyway.
I have found that the Hornady bullets out perform the Berger’s in my particular rifle. It’s been shot with both. I’ve never toyed with the SMks however. Have fun, use caution, and listen to what the rifle is telling you when you load.
