I have a Win 70 375H&H bolt that is not used due to another lighter 375 H&H I prefer..The Win 70 is a heavy gun with scope at around 10 pounds.

I am contemplating reaming the 375 H&H out to 375 Ultra and gaining amother 200 fps with a 300grain bullet to 2700 with 20 grains more powder than an H&H. It will deliver 4850 fpe and only drop 23 inches at 400 yds with a 250 yd zero.This is a 5 inch gain over the 375 H&H at 400 yds.The action is not Weatherby sized so the ultra line of cartriges is the max that will fit.

This will make it a long range elk/moose gun(2350 fpds at 400 yds) as well as decent Big Bear medicine shooting 300gr Swift A Frame bullets.

Opinions? I have several 300's,a 338Wm and 416 Rem as well. Ream it to 375 Ultra or just sell it??
