I shoot a Model 94 Winchester, bought new in 1958. It probably has had less than 2 boxes of factory loads thru it in this 50 years of ownership, but has had HUNDREDS of reloaded rounds thru it.
Trim the case to prescribed length, and lightly CRIMP IN THE "PROVIDED CANELURE" on the bullet. It ain't rocket science. It's that simple. UNLESS, your shooting them in a box magazine, or single shot. Then you can play.
I put a Lyman aperture sight, and a post front sight on it YEARS AGO, and can consistently hit 1 gallon water jugs at 270 yards with my loads.
I use a gauge on all re sized brass, and if they are not OVER LENGTH, I don't trim them. I set my bullet depth to the canalure, and lightly tap the case mouth against the crimping groove in the die to crimp it in. It takes practice, but I have had about 38 years of it. This is an easy round to load for tubular magazines, and as I said, it ain't rocket science, but I suppose you could make it complicated if you chose to. It's a good round to start kids out on, and old farts like me like it too.
After playing with other rounds for years, it is now, once again, my ONLY big game rifle now, and I am well armed for anything in North America with it, despite what gun writers and other so called experts say.
