I believe the stock has enough room for a heavy varmint. Not positive though. Mine has a ton of room around the sporter barrel. The stock has the aluminum block in it. It required a longer front action screw. I like it. It is heavy though. Probably not heavy compared to a lot of rifles on this...

Bobby Hart stock with aluminum block

New remage barrel to come in a few months. For me the short barrel carries well, but my rifle jumps a lot and hard to watch impacts. A muzzle brake is a must for me.
Yea, I forgot it was belted, but still the same as far as the shoulder goes. I try to stay away from belted cartridges. Nothing wrong with em, just never viewed them as necessary or appealing.
Like RidgeRunner said,
Check your headspace. You may have a tight chamber. If you know anyone who reloads your cartridge, have them slowly push the shoulder of a once fired brass back in small increments until the bolt closes with ease. Or have him pull a bullet from an unfired round that is...
