Re: 375 Allen Magnum repeater....

Kirby,

I suspect that the new 500 cal would be purely academical. As I said I used to have a 500 A-Square and a 460 Wby, 458 lott and a watt. Now back then I had a lot more muscle than today and I am bigger than the normal person. The recoil was not managable. I never could shoot it accurately out of hand and I sold the rifle/s. I never could achieve more then 2350fps with a 500gr Barnes bullet. Tested it at the SA Police Forensic lab with all the powders available and suitable to that cal but nope the proclaimed speed by Art Alpin in SA was not achieved. Gladly so, the recoil was astronomical.

Seen so many buffs killed by a more accurate bullet (even .223) than a big magnum.

There are however always a place for a new cal.

I do like the 338 AM and 375 AM. Longrange shooting cal in high wind drift makes sence. I am not familiar with hunting in the US. Planning to hunt there in 2011.

That is if I can get past your Visa control. They are extremely difficult and rude. Cant blame them. So many idiots want to hi jack your country.

If we started right now it would be so close I could not garantee it. I have been working my rear off to get my shipping times cut down. At the first of the year they were right around 26 months shipping time from order. Currently, after this batch of rifles, I will be around 16 months. By the end of the year, my goal is around 10-12 months. That will be about the shortest I could do with the time it takes to get alot of these rifle parts in shop to build on but working hard to get to that point but as I said, it is probably around 5-6 months out if things keep going as they currently are.

Re: 375 Allen Magnum repeater....

Casspir,

The design goal of the 50 AT and the 458 AT for that matter was never as a "Stopper" rifle but for an option for a heavy tactical rifle in the class of the 50 BMG but in a much lighter rifle.

Something that offered legit +1000 yard reach, more kenetic energy then the 408 CT but in a comparible weight rifle.

The rifle design was to be around 18-19 lbs. Lehigh makes a solid high BC bullet for the 458 caliber and at the time I designed my 458 AT reamer, Wildcat Bullets was going to order bullet making dies for a 600 to 700 gr HPBT lead core bullet in .458" caliber with a BC in the .800 to .850 range.

The 50 AT was designed around the 750 gr A-Max and it can drive this bullet to within 100 fps of what the standard 50 BMG can drive this bullet to using conventional 50 BMG chamber pressures.

All that said, if loaded to more moderate levels, either could be chambered in a rifle such as the CZ magnum receiver that will accept the 505 Gibbs and use conventional big game bullets.

Yes, recoil would be far more then pleasant!!! I tested the 50 AT in a 16 lb rifle with poor muzzle brake for the rifle design and recoil was brutal. With the new muzzle brakes I have now in the Painkiller line, I suspect it would be much more pleasant to shoot but have yet to test that theory trying to get caught up with shipping times.

Re: 375 Allen Magnum repeater....

Thanks Kirby for your response. I appreciate how busy you are and that s why I was so pleased to be able to get your 375 repeater without the wait that you had warned me would take some 18 months. I ve started loading for it and look forward to practicing popping some paper with pills in the near future before elk season.

As far as a .458, I ll hold on that for my Africa trip next year but I go back nearly every year so I ll check on your waiting list for it down the road.

Keep up the great job and producing the works of art we are privileged to use.

Re: 375 Allen Magnum repeater....

Kirby,

Do you have a case capacity for the .375 AM in grains of water? I think the stock .375 CT is 151 and was curious how much volume you picked up in your improvement.

Alternatively, what would the capacity be for Retumbo when loaded to the base of the projectile? I assume you have more capacity than required to reach a max load of Retumbo?

Thanks
