Allen Magnum Brass worries.....
I am sure most of you are aware that Jamison International has closed its doors rather unexpectedly. In fact so unexpectedly that I was not able to get my headstamp tooling from them before they disappeared, still working on that.
Anyway, with them going out of business, my 338 and 375 Allen Magnum brass is no longer available from them. I instantly started working on a new source for brass for my wildcats and my customers.
I am happy to say that I am working with Bruce Bertram and in the process of investigating the possibility of having him make custom brass for me. I have gotten some of his sample 408 CT brass and have been extremely impressed with it. In fact, it appears to be significantly stronger then the Jamison brass we have been using.
Another plus is that it also seems to be much more consistant in case weight and volume as well.
So for the time being, if we have to use the standard 408 CT brass for the 375 ALLEN MAGNUM and their 375 CT for the 338 ALLEN MAGNUM, we are still in business so do not let this brass issue worry you at all. We are still in business and in all honesty, this brass looks like it will allow us even more performance out of the ALLEN MAGNUMS based off the 408 CT.
As mentioned, I am working with Bertram as we speak to get correct headstamped brass for the 338 and 375 AMs and also working with him to see if it will be possible and practical to have them build me correct headstamped brass for my brand new 300 and 338 Raptor wildcat which are based on a highly modified 338 Excalibur parent case, formerly made by Jamison as well......
Just wanted to get everyone an update, while this Jamison issue gave me a scare, in the end, it looks like it may actually be a blessing and we may possibly get brass that will let the 338 and 375 ALLEN MAGNUMs reach their full potential. It appears that this Bertram brass will allow us to work in the 70,000 psi range. That is a significant step up from the Jamison brass which would loosen primer pockets at around an estimated 62,000-63,000 psi.
The good old days of using the TTI 408 brass in the 338 AM to get near 3500 fps with the 300 gr SMK may be on the horizon again!!!!! Combine that with the new Berger Gen 2 Hybrid 300 gr and we may be getting a significant performance boost.
