Re: 510 AM test

Ducksinalaska,

Anyway to get a few cases shipped my way to take some measurements on?

Re: 510 AM test

>>Richard tells me 1000 gr ULD RBBTs are a possibility!!!

Hey Kirby, I probably missed it, but what twist? I have a new fast twist (9.5) SA 50 BMG I had built specifically for 800gr and higher pills, sub-sonics and .308 Sabot's. (no muzzle break when firing sabots).

It only has a 30" pipe and not nearly as hot as your 510 AM, but it should be good for load dev and experiment.

As soon as I get Richards site updated I'll email him and order some big 50 BMG pills.

Re: 510 AM test

I have a 1-15 standard twist but I believe it will work with the Wildcat bullet. If it does not work with the ULD RBBT, I am sure it will work with a ULD FB which will not give up alot in BC.

I am not a fan of fast twist barrels in 50 cal. From the tests I have read using lead core bullets, fast twist barrels are very hard on a bullet with this amount of mass. If your using solids this is not a concern obviously.

Re: 510 AM test

Yes, that's what I've been told too. Every manufacture is using the 15 twist. I had to wait a year to get the fast twist Lothar Walther barrel. But my other three 50's have the standard 15 twist. This gun is a test mule, primarly for 308 sabots and subsonics. I'll also see how big of a pill I can shoot. I ordered the gun before the 510 AM was announced.

I think a 1-12 twist might be a reasonable choice for 800gr+ projectiles. The 9.5 seems way overkill for a 50.

Re: 510 AM test

I would agree, if I ever get into a faster twist 50 cal barrel it will be a 1-12 or 1-13 twist. We will see how the 1-15 handles the lead cored heavies first before ordering a custom twist barrel though!!

Have you tested your 1-9.5 yet? how did she shoot?

Re: 510 AM test

Kirby that is a monster.

Any pics of the rifle? or should we just refer to an Abrahms.

That is some serious horsepower.

Great stuff enjoy...
