I have some .357 pistol bullets and some TrailBoss that I would like to combine into gallery loads so my 10-year old grandson can fire my Marlin 336 in 35 Remington. He’s already a good shot with his 22 single-shot rifle and has fired my Ruger American in .223 Remington.
I plan on using Berry’s 158 grain plated .357 pistol bullets, and I’m planning on just plinking at about 50 yards. The Hodgdon site shows I can figure the case capacity by seating a bullet and marking the case. That will give me a 100% load with TrailBoss. Reducing that load to 70% and working up to find the accurate load is the next step. Does that sound about right?
