Hi, congrats on the rifle! I have a renegade hp .303, it uses the same action block as the wolverine. My two cents, it is loud. Even with a donnyfl moderator. Make sure you get a single shot tray, it should be included. Daystate makes a new magazine that is still expensive but works really well. Huma makes a regulator, I never used one, but there is a shot curve using the Harper slingshot system, it is a very subtle curve, but a curve none the less. Imo if you are benching the rifle, contact joe brancaton for a in line regulator from big tank to rifle. You could set the external regulator with your tank and shoot all day at the same pressure. That would be nuts. Also, the .303 is good for coyote and turkey. I use a heavy jsb .30 but the .30 polymag worked well also. You bought a beautiful, well made rifle. Congrats.
