  2. Thanks to Daniel Horner, the AMU team, and all of the folks on base that worked very hard to put on a stellar match! Everything was well thought out in stage design, the facilities were excellent, and the staff was great also! I look forward to this match next year, and am already planning a return trip!

    Anyone know where pics will be posted?

  3. On SJC, I got it mounted and took it out for testing over weekend. Had two types of rounds to be tested, 77 HPBT MK hand loads, and WIN 55 grain white box.

    Started with one round in mag and gas block closed, with the 77gr, using 12" square target at 25yds. Had the jet ports pointed up, as close to straight as I could get it. Had to open up gas block (Syrac) 6 clicks to get bolt to stay back. Recoil reduction felt good, but dot in scope was moving slightly up and to the right (I'm right handed).

    I want ahead and switched to WIN 55gr, and had to open gas block up 2 more clicks to hold bolt back. This gave some more felt recoil, as reciprocating mass came rearward with a little more force. Still noticed slight up an to the right with dot on center of target.

    I brought some shims along, and clocked the SJC to about 1:30-2 o'clock, to try and overcome the up and right movement in glass. It did help, and I moved back to 30 yards, and felt pretty good with decently quick doubles on the 12" target. Overall, I believe this brake has given me the best result of all brakes used and tested.

  4. I think it's about .340, then .300, then .260, then .240

    Only prob is the brake has been heat treated to mid 50's R/c

    Would have to tool post grind holes open

    I kept holes that size, trying to get some right side jet port effect to compensate for my left arm torque... I suppose I could rotate the brake, and open it up like you say to see what happens

  5. I will post up a side shot pic at halftime.. I can't remember how much I stepped the hole diameters, but it's 3 different sizes... They are just too close to one another in size at te moment..

    I machined them conventionally, using a Bridgeport and a 1/4" ball endmill... I machined each baffle pocket, with the rectangle around the baffle opening... I then came back with ball endmill and stepped down and over, using a calculated over-and-down formula for every 2.5 degrees. Then finished with stones and some polish

  6. Koop,

    On the trapezoidal one shown above, I made the face of the baffles volcano shaped, thinking it would peel away better... I believe the abrupt, flat faces work better, giving better recoil reducing performance...

    And yes, it is under the 1" diameter rule, and 3" length from end of barrel

  7. I've tried several brake combinations since I made this brake, and tried it out...

    Of course I used the JP Cooley comp as my control, and tested all others against it.

    I've used an Mstn PRI for quite awhile, and was fairly happy with the results... Recoil reduction was similar to JP, and muzzle rise was minimal...

    I tried a Seekins brake, but it didn't help me with muzzle rise as well... It may have been due to not using the locking washer, and screwing it onto the threaded barrel portion all the way, and negating the effects of the radial forward ports...

    Tried the Rolling a Thunder, and it was super heavy on front end, but had good recoil reduction... Needed a hole drilled in side to overcome my torque of left hand hold, but it's weight made me shelve it

    I've recently purchased an SJC Titan, and am in process of machining it to fit my old JP barrel... One note I left out is that the old barrels had an oddball thread size, I imagine to prevent folks from slapping any old brake or suppressor on there... Thread was 9/16-28, so every brake I've tried, I've had to bore new hole from purchased 1/2" diameter, and run 9/16" tap in bored hole...

    What I'm wondering lately, is if the weight of a muzzle brake can adversely affect a barrel's accuracy, since a heavier brake would cause barrel to 'whip' a little more during firing...
