45-70 Marlin mold

Hello from Wales in the UK! Casting Virgin here. I've been reloading for years but have never cast my own bullets. That's going to change soon but I have no kit yet. I've been reading past posts on this forum (and elsewhere) and I'm beginning to realise how much I don't know :o I've been reading Lym...

Re: 45-70 Marlin mold

Many thanks for your reply. I'll try and get that measurement before finalising the design. I also think I'll go for a gas-check base.

How do I know whether to opt for stud/locknut or screw/set screw for the spruce hinge?

Best wishes,

Ben

Re: 45-70 Marlin mold

I made some measurements using the technique described on this forum (lead-filled case and lead slug, obdurate do by tapping rod from muzzle): http://i68.photobucket.com/albums/i10/xavierdoc/more%20pics/B63BA55F-9845-4F4B-AD42-CC0FFE4A2FA5.jpg Please note, this is using fired/unsized brass which is ...

Re: 45-70 Marlin mold

The 458 Gator gas checks don't seem widely available here but I dare say I could track some down or get them sent from USA. I wouldn't want to compromise if the .452 are inferior. Hopefully ITAR restrictions won't block export! These seem to be my two options: http://i68.photobucket.com/albums/i10/x...

Re: 45-70 Marlin mold

I can get .458 gators, so that problem is solved. Can they be seated and crimped with standard kit or do they need specialist equipment? I've been looking for a sizer that could take as-cast .463 bullets down to .462 or .461 but can't find any. My bore slugged at 0.4545" three inches from the m...

Re: 45-70 Marlin mold

At the moment I have no casting or sizing equipment. I'm trying to keep costs down so a new Lyman-RCBS lubrisizer might have to wait. However, I'm prepared to fork out on the things that really make a difference in the long term. Not sure what my alternatives are, though, if I want to size to an unc...

Re: 45-70 Marlin mold

Thanks for that, I'll try and contact him on Castboolits. If he won't ship to UK or can't make what I need, .463 bullets might be a dead-end. So if I go for an as-cast diameter of .462, these should shoot in my gun unsized, since that's exactly what I'm doing with my current bought cast bullets. I c...

Re: 45-70 Marlin mold

Sounds... Involved! Does it mean lapping/fire-lapping?

How do I know my "tight spot" isn't due to my amateurish bore-casting? I guess I could repeat it, trying to hit the same spot as before.

Re: 45-70 Marlin mold

I read your guide to making fire-lapping bullets. What abrasive do you use and do you need to "go through the grits" from coarse to fine? How do I know how many shots to fire? I'm instinctively afraid of "grinding-out my throat and rifling!" Is there any reason I can't get on wit...
