Carl sent this video of the A-30 being shot with commercial 125 grain ammuntioin and the 200 garin sub-sonic that has been developed. This is a 16" barrel with a normal size gas port and carbine gas. He reports 100% functioning and that the 200 grain bullets were easy to work up. The vidoe is dark and I will work on getting it lighter. Shots are super and sub and if you watch the muzzle flash you can see the diference. The rifle and ammuntion will be shown and acailable to be shot at the SHOT show. SUBSGreg |

Not sure on that. Maybe Carl will chime in.
Greg
Carl says Dragon Head on that one.

What twist for 30 American 1:7 , 1:8.5, 1:11.
I plan to buy 1:11 twist should stablize 208 Amax single loaded.
I have 6.8 bison 1:7 that will stablize 200 gr.
so 240gr. For subsonic I see 1:7 but why 1:8.5?

What bullet is he using for 200 gr. to get that good functioning?
Sierra has a nice 180gr RN , speer has a 180gr mag tip, speer has a TBBC 200gr.

For subsonic I see 1:7 but why 1:8.5? A 1:11 won't handle a 200 grainer in this one. We offer a 1:8 for guys that want it. It was an old odd twist rate for the 300 BLK's. Greg |

Made my order ....hmmm maybe try and change order to 1:8 or 1:8.5 Monday. My brother would not believe you could shoot 200 gr. no matter what I said.
so the bullet was 200 bear claw got to research that must be more blunt profile.
The video seemed to show fed and cycled fine no single load deal.
Makes more interesting option for us Alaskans.

OK Speer sells 200 TBBC, it has SD of .301 and BC .392 (G1) Trophy bonded bear claw
Was there a chronograph to see how fast you could shoot 200gr.?
Too bad this forum doesn't have a sticky page to collect reloading data on 30 American (and 22x6.8, etc.) would really help sell these wildcats.
Thanks.
Tim

Tim They weren't going for supersonic only subsonic relaibility. They established a good sub load via chronograph with the 200's and then made the clip. Load data is scattered throughout. These are wildcats and hard fast non-pressure tested loads would be iffy to post. We have tested many of the loads you see here and we don't publish anything over a nice safe cushion pressure in each cartidge. You may go faster and many have on other cartidges but the main fly in the ointment is that they aren't making them. I've seen huge wildcat loading tables on some cartidges recently and when you start seeing the little guys outrunning or matchng the bigger guys you know you they are playing with fire. The loading rationale that if they can get more powder in there it's safe is rampant currently. We don't do that. We had three guys shooting this compiling a comaprison sheet for our development. Compined knowledge and experince is right on 110 years at the relaoding bench with decades of comeptition and feild application behind them. Three other chambers were shot prior to this one being released. Al were scratched because of various reasons. You have the best one we could design being delivered as I type this. I am always willing to share on a 1:1 basis. The American 30 has been tested with a muiltitude of powders and we think we've done a good job. One thing is that the case capacity is so small that many powders while working well cannot be used in aprogressive press becuse they literally are up in the case necks. Compressed loads are nothing new to the staff and we have used them in testing. Greg |
