.376 or .377 bullets are NOT going to do the job. I'll bet you need a .380 cast bullet and larger if it will chamber. I shoot LaserCast .380 cast bullets in my 38-55 over 30 grs. of 3031 powder. Go to You Tube and search on JB vs 400 to see how accurate they are. It show shooting the 400 yard metal plate.
