BLACKBIRD barrel break-in--375 Cheytac Benchrest

rpierce said:
My round 5 port magnum is a side discharge and is 1.5 diameter. It could be turned down flush with your barrel for a seamless appearance. The first port is 90 degrees to direct the blast away from the shooter. The proceeding ports are angled to further reduce recoil. It is designed specifically for the chey tac cartridges. It will damper the recoil down to nothing. I have a customer who sent me a video of a kid shooting his 375 cheytac improved in a 17 lb rifle and had no issues with recoil. My website doesn't have the round version on it yet but if you call in the order I could do it. 125 shipped.

Love the stock.

How many weight for those stock? Is it fiberglass?

Do they have those stock with 1.250" clamp barrel?

Stock is carbon fiber, 17 pounds, and it has 1.250 inserts for the block.
While I was waiting on the Cheytac I put a Bat SB 6mm XC in the stock to try it out.
The XC had a 1.250 inch barrel. Inserts worked great.

With the BAT XC installed

I hope to do a little load testing Sunday. I am going to try 133 gr and 134 gr of Retumbo. I will chrono and check SD along with accuracy. So far I have only shot 132 gr and fired it 23 times at 100 yd, 1400 yd, 2000 yd.

Isn't it a little cruel using a small dog as a target, even at 2000 yards! :p Shot three or four was pretty close. :D

It was a long hike in there so I took Charlie to protect me from Coyote attack. He is my main sidekick and goes everywhere with me.

I bought it from Sam Hall. It is a Scoville. Bob Scoville I believe. I tried googling but found no contact info. Send Sam Hall (HUNTER3401) on this board a PM. I think he can direct you or tell you if Scoville is still in business.
 
I tried 3 powder charges. 132, 133, 134 gr of Retumbo. Each increase of one gr resulted in 10 fps increase in MV. Best SD was at 133, but I liked the group at 132. I may try 130 and 131 gr's next.
