.350 RM is my go to hunting round...have had several since the early 1990s... At this point I only have a Model 600 18.5" and a custom Montana Rifle Company 22" left...

Bullets...the optimum bullet for the .350 is the Speer 220. With its flat nose it fits perfectly into Remington 600/660/SEVEN and 700 SA magazines which are limited to 2.800 LOA. The base of the bullet can be right at the base of the case neck and still make Max LOA. With 60 grains of 748 they run 2660 from a 22" barrel.

I have killed several deer with that bullet and a friend several black bear. Only one bullet recovered and that was on a bear that was standing at a bait barrel about 40 yards away. Bullet hit the shoulder, down through the lungs, heart, ribs and stopped in the fat to the chest just before breaking out of the hide... Perfect mushroom. It is a tough bullet.

Of the deer I have hit with the bullet they have: dropped in place (35 yards on a running deer), 30 yards (60 yards on a walking deer) and 80 yards (135 yards on a walking deer).... I believe my friend killed three black bear...all DRT.

Lee will make you a Factory Crimp Die if you send them a dummy round. Does an excellent job of putting a crimp anywhere you want it on a bullet.

If you are trying to form cases, have you considered 10 grains of Unique instead of expensive rifle powder. I use it with the Hornady 180 grain XTP handgun bullets for my grouse load...

Good luck in your quest...Bob
