35 Remington Gallery Loads
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? |

You appear to be right on the money. 70% fill with TB is a good starting point.
I use TB for plinking loads in a good number of rifles, it tends to do well in the 80-90% fill range, depending on the cartridge. 35 rem is a bit smaller than the ones I use it in, so your mileage may vary.

First try
These are what I loaded tonight. Hornady 357 XTP with 9 - 12 grains of TrailBoss. Don’t recall COAL but loaded to the groove and gave it a healthy crimp. To the base of the bullet was 12.5 grains of TB.
If I continue this I may need an undersized mandrel for my resizing die. They were just undersized without the crimp. Will report how they shoot. |

One word of caution, trailboss tends to burn erratically near 100% fill, and it does not like to be compressed. I would recommend to not exceed 90% fill for best results.

Thanks for the caution. I planned on starting with the 9 gr load (75%) and working up. That’s why I started with 12 instead of the full load at 12.5. Looking to duplicate 357 rifle performance.
