Grendel and cast bullets.

[Von Gruff]

I had a cast bullet mould made to my design and sent some to a couple of guys to test with the same good results that I had. In light of that there is a group buy started on cast bullets for a mould to cast the same bullet

It would be interesting to see the difference between that mold and the mold I worked with another designer for a group buy.

What alloy are you using and what speed you killing goats with?
Thanks

I know Von Gruff uses bolt guns so cast bullets are fine in that application, but have heard that cast bullets in gas guns will eventually kill the gas system. I guess the wax/lube plugs things up. Does anyone have any first hand experience with this?

I have been shooting Cast bullets in 2 AR's for nearly a year now .. 300 Blkout, 458 Socom
well over 1000 bullets thru the 300 and no buildup in the gas system or either suppressor ..
with that said I powdercoat all my rds ..
I know many others at castboolits.com that say the same thing some shooting Naked bullets (no PC coating) .. no buildup in gas system and if properly sized to the barrel no leading

and I am on the von gruff group buy for the 6.5 mold

attached is a group from my 300 Blkout .. First shot thru cold suppressor seems to always be a little off of the rest of the group

I am still trialing bullets as I was able to get to about 2300fps with a 70/30 ww/lino bullet with good accuracy but it went through 8 water jugs without expansion so wouldn't shoot goats with it. Have got a straight ww to 2200fps but haven't done expansion tests with it yet although I believe it will be good to go. Have been working with my 47/33/20 (ww/Pb/lino) and have got over 2000fps so far with moa 5 shot groups but my goat shooting is mostly in areas with shot opportunities out to as far as the eye can see from 6-700yds to well over 2000 but I usually cat get in to within a couple of hundred and last time out carried a few of the 47/33/20 loads but am loaded with the A,Max's generally so haven't poped a cap on a 6.5 cast bullet at meat yet although have a lot with my 7x57. I can only get onto the goat country from Nov to May so it is closed down for the winter as it becomes impassable. Will continue trials over the winter and hope to get a kill with it next summer.

Have tried 4198 (with and without buffer) and varget and will run BL-C2 in next tests. Have a great little plinker load with Blue dot.

My Cast Bullet For The Grendel

I've been using a Rapine 6.5mm mould 150 grain bullet sized .266" with very good results. Using four different powders that average 1 1/4" at 100yds. I took the load data in Bergers for the 130gr bullet and used 15% below their starting load, and it works nicely. Cartridge overall length is 2.213" in a Lilja 18" AR barrel

Welcome to the forum jzdryfly. That is a good looking bullet and I see you have ordered a mould so look to see some good reports when I all comes together.
