Just thought I'd share my experience with the Lasercast pb bullet in my .375.

The bullets are made for the 38-55 Winchester, but I ordered a batch sized to .377 (no extra cost, either).

I am using WW brass, CCI large rifle primers, and 15-17 grains of Green Dot. No filler. I bell the cases with a .357 mag flaring die by hand with a mallet, and apply a mild crimp.

All of these shoot a clover leaf group at 50 yards off my knees with a sling, recoil is very mild. The 17 grain load does lead a bit, but only after 40 rounds or so...according to the Lyman manual it's probably around 1700 fps.

I can hit 12" rocks all day up to 300 yards, but it takes the slugs a while to get there !

The rifle is a custom built on a 700 remington with 26" bbl.

Sure beats expensive jacketed bullets and recoil !

Ben,I also have been using Cast Bullets in my Rem.375 h&h Safari.
Although I'm making Lyman 375449's out of Lino Type alloy with Hornady gas checks and LithiBee Lube.
For Powder I've been using 22 grs. of alliant Blue Dot and get about 1,800 fps with little or no leading.
These can be shot all day without recoil headache!

Good Shootin ,
