So I’ve been loading pistol for almost 8 years now. Everything from .380 to .45. When I started I bought the Hornady Lock N Load kit and put everything together. Loaded many thousands of rounds since then. I weigh every charge and it’s always been dead on.

So I’m getting into rifle reloading and bought a separate powder thrower for rifle so I never mix up powders in the thrower. It comes with the rifle rotor for heavier charges. While cleaning it I see that the rotor for my other thrower that I have been using for 8 years is also a rifle rotor. Since I had never specifically set out to load rifle I never even knew there was a difference.

It’s obviously safe since I’ve never had an issue but is it a practice I should continue? No rush to buy a pistol rotor unless I have to.

I use my Hornady vintage 1980 rifle thrower for coarse pistol powder such as Red Dot, Unique, 800x when my charges are around 6 or more grains. If I load my other powder, 231, I use the smaller cylinder pistol thrower for 4 grains about. the ball pdr of 231 measures so well I don't weigh every charge, but check often. The other powders w the rifle thrower I weigh every charge starting low and trickle up .

I use HP38, same as 231. .380 loads are 2.8 grains. Drops them dead on every time.

"If it aint broke, don't fix it" comes to mind. Seems to be working fine for you for the loads and powders you use.

In the RCBS rotors the only difference is a bigger hole. For 223 you can get by with the pistol rotor, Large calibers (more powder) will probably need the rifle rotor.
IOW

You can load small charges in the big, but not large in the small
