Pretty nice cartridge. I have had 300RUM's and have a STW. But barrel life might be limited. Kick can be severe but not near as bad as most loads in 300RUM. I would say recoil is like a 300win mag with 180gr bullets.

I say it will be around for a while, but who knows. For me, I know I would burn the barrel before that happens. But if you are not a reloader, and don't plan to shoot alot and keep many years, I would be concerned about the future.
