    Gunsmithing Will a clausing 4901 work?

    That lathe looks like it’s spindle bore is too small and the bed is too short. I have a 40mm spindle bore and it’s limited to 1.5” barrels. If you’re willing to chamber using a steady rest; get a 40” bed. The only time I switch to metric gears is for AI rifles. Cheers,

    Camera/Camcorder as a spotter

    I use this rig to record my strings. It’s funny playing them back and listening to some of the calls that don’t match the splash. :p Cheers,

    Swaro STR 80 MRAD - Reticle Leveling

    The rig in this picture is over kill. A level panning base and scope level is all that is required. I like to use the ball head to position the horizontal stadia through the target’s horizontal center line. Then pan the vertical stadia to align with the impact. Now the corrections can be...

    Need advice...

    The HTI is more flexible. Both HTI and Barrett rifle barrels are expensive to replace. A 416 Barrett barrel won’t be competitive past 2000y after ~1000 rounds or less. I was shooting about 100 rounds per match. So, plan to replace the barrel often. Check out Cadex rifles. They use a...

    Need advice...

    I shot with NorCal URSA before the range burned down last year. Go watch when they start shooting again. But, until then; check out the 1K matches at Sacramento Valley. There are some awesome shooters there. Edit: I just noticed you want to start with a boomer. It’s gonna be difficult...

    Gunsmithing For guys that have done DTA SRS barrels, looking for your input.

    Sorry, I miss read your question. I believe the barrel shank should be turned coaxially with the chamber; after the chamber is dialed in. The issue is the extension is cut to receive the chassis lock cam and it would be nice to keep the lock aligned to the chamber. The extension should be...

    Gunsmithing For guys that have done DTA SRS barrels, looking for your input.

    I think you need to check the extension and barrel separately. The face of the extension and the barrel shoulder are the alignment surfaces. 1) The threads should have enough clearance to allow the two surfaces to mate. 2) The extension’s face needs to be parallel to the extension’s bolt...

    Gunsmithing Lathe advise?

    This is the manual lathe I would get with an unlimited budget. My 13x40 is the baby brother of this one. Made in Taiwan. I think Precision Mathews may have a version of this machine. Look for one with similar controls and specs. I bought new and appreciate having a tight machine. Although a...

    Gunsmithing Lathe advise?

    I have a quality 13”x40” with a 40mm spindle bore and 3hp three phase motor. The only thing I would change is the spindle bore. A 50mm spindle bore would require bigger stronger bearings and allow me to chamber 1.75” barrels through the head stock. Cheers,

    2 "Train of thoughts" arising in ELR

    That is the requirement I used for testing. It was the worst case scenario. The 2018 KO2M day-3 was 16-rounds in 10-minutes. So, 37-seconds per shot is competitive pace. Cheers,

    2 "Train of thoughts" arising in ELR

    I think the answer depends on the ROE. The toughest requirement was 10 rounds in 5 minutes. I ran a 338 at 3600 FPS and the dispersion noticeably increased after 6 or 7 rounds. At 2500y plus; it’s hard to compensate for that. I’ve since settled on a 375 cal at 3000 FPS. Consistency makes...

    Defiance Prefit

    Call Defiance and ask them. They’re good people. I have two Defiance Deviant short actions. There is almost one thousandths difference in the head space between them. The barrel timing is close to identical. I can’t measure the difference. I tried to order a Magnum bolt for them and...

    215 berger hybrid stability

    I’ve gotten hits at 2500y with them. The 215 Hybrids run 3200 FPS out of my Norma Mag. AB says they went transonic at 2155y and the 2500y impact velocity was 1120 FPS. Cheers,

    What’s the parent case for the .416 Reed? It looks like a BMG sized action. Thanks.

    Gunsmithing Barrel wear question

    My guess is that your chamber didn’t grow. Your once fired brass from the first 50 rounds just wasn’t fully fire formed. I use a Hornady style comparator zeroed on the go-gauge used to chamber the rifle. I chamber my barrels 1 thousandth over go-gauge and the head space closes down a bit after...

    Interesting take on ELR matches: Mark and Sam

    I would like to see something done to equalize the environmentals for all competitors. I understand the logistics of trying to weed out the top 8 out of 100 shooters. But, the weed out stages distances are so short the environmentals can be ignored. So, with 8 shooters it should be possible...

    Gunsmithing Correct barrel blank length??

    The extra length required depends on the finished bore dimensions. A properly lapped bore won’t have more than 1” of belling. So, a 29” blank can be finished at 28”. Cheers,

    50BMG

    The FCSA guys told me to keep my mouth closed while firing the 50s. Rumor has it the reigning KO2M has switched to a 416 Barrett. I shoot a 375 SnipeTac. It’s an improved CheyTac. 400gn @ 3000 FPS.

    RRS Leveling head not so great?

    You need to use the right tool. Check out the RRS Anvil http://www.snipershide.com/shooting/threads/rrs-anvil-ball-head.6872843/#post-7037250 Cheers,

    50BMG

    Check out https://www.fcsa.org/wwwroot/visitors/about.php those guys know what’s up with the 50s. I shoot with a few 50 guys out to 3000y. They are competitive in high winds out to about 2000y. After that their trajectories make the target too small. Their bullet impacts are almost sideways...
