WWE –
I do understand your hesitancy to learn/begin reloading. Most of us are also busy, too, yet we find a way to do what we enjoy apart from the workplace or other commitments. When I first started shooting BPCRs, there were few (if any) commercially loaded BP ammo products available. You have that option, though it is an expensive option. It cost me in the neighborhood of $500 to get brass, primers and all the reloading equipment for my first 45-70 (this was back in the mid-90s so adjust for inflation). I also set up to cast my own bullets, so add another $200 for that equipment. Except for the dies, powder, brass and bullet moulds, all other equipment can be used for virtually any other caliber you may have. If you shoot BP loads (and with your Roller, I would strongly encourage that) your brass will last for years and years – I am still using the same 200 cases I bought nearly 20 years ago and I have reloaded them at least 75 times.
Long story short . . . I can still reload 100 rounds for my 45-70 for about $20 (primers, powder and lead). A lot less than $35 per 20 plus shipping or tax for commercially available ammo.
Do what ya gotta do, but you can shoot a lot more if you’d start reloading.
I commend you for the volunteer work you do, if only we all had that calling and dedication . . .
Best to you and yours . . . Otter
