I decided to go with the 358 Winchester cartridge for my Encore pistol. The barrel was made by MGM. It is 12 inches in length, including the muzzle break. Bullet will be a cast, 200 grain, gas checked design. The mold is an RCBS mold. Mold should be here tomorrow, and barrel should be here any day. Bore size is 358. Drop size of bullet is suppose to be 358 with #2. I would have liked for it to drop at 360-but what the heck. Weight is suppose to be 204 grains, we will see.



I am looking for a good accurate load. I am not necessarily looking for a high speed load. Round will be used for shooting and hunting out to 150 yards(Deer and Groundhogs). I am looking for a powder recommendation that will come close to filling the case, a load that will burn in that barrel length, and last but not least, a powder without alot of "THUMP". I think you guys know what I mean. Any suggestions??? Tom.

A friend of mine sent me this load data from the 1973 Lyman Cast Bullet Manual. Might have some useful information for you.

I shot 25.0 IMR 4227 with the Lyman 358318 HP out of my 358 custom rifle a few days ago.

You might try a slightly lighter charge of IMR 4227 than 25.0 with your RCBS 200 g/c out of a 12" pistol barrel.

As you can see mine shoots real well !

This is 65 yards - 5 shots
