Chamber casting

[7mmlefty]

Anyone have any simple ideas on chamber casting material ?.
Without having to order from the usa.

Sulfur, check fertilizer sales.

cerrosafe. Don't know about a canadian source. Mine came from http://www.buffaloarms.com/

Sulphur.... how much does it shrink? With cerrosafe, you measure a set time after taking the casting out and get exact dimensions. Stick to what the pros use and get some cerrosafe.

Cerrosafe is great stuff, and the way to go if you need to save the cast for a longer period of time. Sulfur works very very well and will suffice for many of the needs for the guy at home.

Thanks guys... can I just use a harder wax?... or pour some soft lead into the chamber?.

I've heard of wax being used, not sure what kind though. Never heard of using lead.

What are you trying to accomplish?

You can use canning wax but it will not work as well as Cerrosafe.

Trying to find throat diameter and chamber length and maybe a bit of internal rifling location on an old 38-55 Winchester rifle.

hmmmm.... maybe talk to your dentist.
There's that stuff they use for making impressions for crowns.

Gotcha. Either sulfur or Cerrosafe will work fine. You will still need to add the dimension from bolt face to barrel face, headspace gauges help here.

The L.A. Silhouette Club ~ scroll down for chamber casts.

Whatever you use must come out easy, be careful when pouring, a little goes a long way.

I used a green jeweller's wax in Lee Enfield chamber once. Set a lead bullet in first, then warmed up the chamber with a propane torch, (not too hot, and I did remove the stock) so the wax wouldn't cool too fast and poured in the molten wax. Then let everything cool.

Tapped it out with a 1/4 wooden dowell. The result was perfect, and the bullet stayed with the wax.

I've only done this the once, so I've never used anything else. You did ask about wax, but the products the others have mentioned are probably better.
