I looked into the reloading press issue that this round brings to light(thanks Matt), I was first thinking that my RCBS 50 BMG press would work, but I can't find a bushing to take the 1-1/2" die down to the 1-1/4" die that the Gibbs utilizes. I will probably have to have one machined and I should be in business. Ordered 40 rounds of Norma factory that was discounted substantially @midway and some barnes and Woodleigh bullets. Hell, I only have 11 weeks and 6 days to get ready for her arrival.lol
Velo Dog,
The extra crosspin is a great idea, can you explain the placement of the extra recoil lug to me a little better?
Bullthrower338,
Yes (and Royal27 was right, because wow am I ever giddy about this opportunity to share my opinion).
The Gunsmith contours a metal block to fit the bottom of the barrel, and fastens it in place, either with silver solder, or screws or an industrial adhesive of some type, or a combination of a couple of those.
He then he cuts out a corresponding socket into the barrel channel of the forearm, (about half way between the forend tip and the front of the magazine box) but, with extra space/cut somewhat longer behind where this "recoil lug" will rest.
Next he cuts a piece of machine threaded rod or the threaded end of a machine bolt to fit laterally/side to side into the extra space behind where the "recoil lug" will rest.
Then he coats the lug with grease or releasing agent of some sort, so that the glass bedding compound will not stick to it and he glass beds the threaded rod stub into place, tight behind where the lug will be
It helps absorb some of the recoil into yet another part of the stock, instead of most of it bashing against the tang and magazine box areas only.
He told me he likes to use threaded stock for this part because it ensures a very firm bond between the rod and the glass bedding compound.
Seems to me a plain/non-threaded stub of steel rod or square stock would work fine or perhaps, no metal added at all, because glass bedding by itself is quite strong but, I am no Gunsmith and might be way off on that.
Additionally, if I am not mistaken, when Ruger was still making their excellent Model 77 Magnum, I had heard tell that they used a similar barrel mounted extra recoil lug but, I am not positive on it because I have never taken one apart.
All these shoulder fired cannons can be reinforced to not break themselves apart but it is a bit of extra work and money.
Cheers,
Velo Dog.
