What's the details on that coating?
I have loaded and shot 45-70 almost exclusively for the last 15 years. It's a wonderful round. If you plan to do as.much shooting as you claim, there is no other way to go than casting your own bullets. Pick up the Cast Bullets Handbook by Lyman and read it cover to cover. One piece of advice....buy a quality mold. I fussed and messed with undersized Lee molds for years until the frustration finally got to me. Marlin rifles tend to like "fat" bullets and with cast, the best fit is 0.002" over bore diameter. Slug your bore, my guess would be it will slug at .457-.458".....this will mean you need a mold of AT LEAST .459-.460. I recommend NOE molds, I dumped all my Lee gear and use NOE exclusively and have never looked back. I have never powder coated, and never plan to, the 45-70 uses a bullet with a large lube groove for a reason. I pan lube everything with great results, and have never ran into problems with leading. Shooting undersized bullets is the number one cause of leading followed closely by improper lubing or bullet alloy. Shooting that volume, I'd stay away from jacketed bullets unless you have a barrel supplier readily available, you will never wear out a barrel with cast and proper pan lubing.
An advantage to using CAST bullets (aside from cheaper cost & enjoyment making them) is it’s so easy to down load them to minimal velocity for practice. I’ve used 10-13 gr of shotgun powder under a 300 gr pill for VERY MILD recoiling rounds out to 50 yards or so. Accurate enough for 3 shot rapid fire offhand practice as well as “moving deer” targets. Now your powder usage is 1/3 of full loads & bullets costs are WAY down. When you want/need full power loads you still use the cast bullets, they perform VERY well on deer, no need for jacketed pills at all.
Some guys seem to get away with 0.001" over bore so for example they shoot a .459 bullet in a .458 bore. I personally have had spotty accuracy going that route. I use a minimum of 0.002" over bore. My barrel slugs at 0.458.....my NOE mold drops them at 0.4605....and I size them back to 0.460 using a push thru sizer and install a gas check at the same time.
