I have been reloading .35 Rem for a Marlin since I bought the rifle new in 1970. Just about any medium fast powder will give good results. Bullet choices are limited. I use Hornady 200 grain round nose bullets.
The cartridge has a very small shoulder. I started full-length resizing the brass, with the result that I was getting case head separations after three or so loadings. This was very annoying until I adopted the sizing technique used by those who reload the cartridge for the TC Contender.
Get a .375 expander die. Expand the case neck all the way down with it. Then just neck size a bit at a time until the case will chamber with very light resistance. This forms a false shoulder that will prevent the case from stretching when it is fired. Then prime, charge, seat the bullet, and crimp as usual.
This is kind of a pain in the neck (no pun intended), but it produces very accurate ammunition and the cases last a while.
