Hi Skeet028;
I've got a Winchester Model 54 .30-30 and have shot handloaded concoctions in it for years.
The Model 54 here is a carbine that was given me by its original owner who originally purchased it in 1928. He said it was on clearance and he chose it from a rack of about 10 just like it. Purchase price was $30. He immediately placed a Redfield aperture sight on it.
I first shot the delightful little rifle years before I ever dreamed I'd own it and found it to be particularly accurate off the bench rest. Once it came into my possession I wanted to try spitzer bullets first thing.
The rifle is in excellent condition with a sparkling bore and really accurate with the Sierra line of flat nose bullets intended for .30-30. It's good for 1 1/4 to 1 1/2 inch 5-shot groups off the bench at 100 yards when I'm in a shooting humor. I've shot at least five deer with it from 40 yards to 120 yards.
The effort to shoot spitzer bullets has been pretty much a bust and I'm surprised at this. I've tried Sierra's 125 grain flat base spitzer, 150 grain flat base spitzer, and 165 grain boat tail spitzer.
I've played with powders and more importantly seating depth. I have a hunch it has something to do with seating depth, but I've never completely unlocked the secret. The rifle's a little stinker for it returns outstanding accuracy with flat base bullets made for .30-30s and also does well with round nose bullets. Shame as spitzers are entirely acceptable for it because of its box magazine and could offer some decent retained velocity should one desire to shoot .30-30 at longer range. Spitzers are just underwhelming in my rifle though and I'm really unsure of why this is so.
The only spitzer bullet load that I could offer is the 125 grain Sierra spitzer over 34.8 grains of IMR 3031. Seat bullet out so as to nearly contact the rifling. This load gives 2428 fps and will group around 2 inches at 100 yards at best.
