    Accuracy International Picture Thread

    The Keymod +2 fits the AI keyslot. I briefly used the +2 and had no issues attaching it before deciding I didn't have a use for it and relegating it to the parts bin.

    6mm Dasher

    Nope. I’ve shot thousands of 112’s and recently started shooting some 115 DTACs. As Lightning8 said I see the same thing. All the local shooters shoot 105’s and a few shoot 109’s. Unless the distances push out past 1k I hardly notice a difference in wind calls or energy with any of those so...

    AIAT - barrel won’t come off

    Maybe try a strap wrench on the barrel if it doesn’t have flats. Or bust out a barrel vise.

    Accuracy International AT-X

    The stock 49 or whatever the nearest fixit stick works for me. My first shot is usually 0.2 mil low and I'm not sure if that's the barrel or suppressor seating or barrel fouling or all the above. My RTZ is consistent so I have seen a need to try any different torque settings.

    AT-x--6BR magazines?

    I have both Gray Ops BR mags and HRD kits and can confirm both option run great in my ATX with a Dasher. I’d probably trust the Gray Ops more with a shorter body or OAL BR.

    Giraud Power Case Trimmer Ya, Nay

    I've had a Giraud for years and it's been good. Some good info in this thread also about the Henderson. I think you can't go wrong with either. Also as a side note I got away from trimming every load awhile ago and moved to rarely trimming when necessary and have no intention to go back. I...

    22GT load data

    0.305 is a rough starting G7 I get using Strelok to convert the multi G1 into a G7.

    300 Norma Mag

    Also just because you have a 10 round mag doesn't mean you should shoot 10 round strings. That was my n570 mistake; after 10 rounds the barrel is about to melt into a puddle of steel.

    300 Norma Mag

    Freebore is whatever AI uses PLUS whatever n570 has burned away. With 245's I was getting 2900 fps but my 27" barrel has lost a ton of speed. I would guess a new barrel should be around 3k.

    .22 BRA

    Have you fire formed a lot of brass with the barrel? I've had barrels do that after jamming a few hundred false shoulders. In my case I think the neck shoulder junction was rounding out with use and the crush fit was becoming loose.

    7mm PRC

    I'll join in this H1000 love fest, my current load data: 67.2gr of H1000 Peterson brass Berger 190gr LRHT Fed 210 27" barrel. 2,915 fps. It doesn't seem like a hot load, easy extraction and no primer pressure signs and it's been good in the rain. I never pushed past 67.6gr since the speed...

    Lapua announces 6mm Dasher brass

    Ok cool. Woulda been much cooler if they launched this a long time ago.

    Lapua/Alpha worth the premium?

    Yes, don’t waste your time and components shooting second tier or trash tier brass.

    Accuracy International Picture Thread

    I shot a proof competition contour (PVA Osprey) without issues with the full bridge. I never paid attention to the clearance when I had the barrel but it must be close where minor dimensional differences can mean the parts touch.

    6mm Dasher

    Speed no, rotational speed yes. And 2800 with a 7.5 twist barrel and 105 hybrids are fine. If your velocity is too slow you won't have enough RPM to stabilize the round and you will need a faster twist barrel. And if your happy with your results at 2800 then stick with it. Trust your...

    6mm Dasher

    Well, have fun trying them out and report back. David Tubb’s 115gr DTAC is a more popular heavy-for-caliber so maybe look into those also. I haven’t tried them or the VLD so I can’t add much more here. I’ve shot a lot of Barnes 112gr match burners and recommend them for a heavy 6mm. They...

    6mm Dasher

    30.0gr would be safe as a starting point for 115 VLDs. Work up as always, I'd guess you could hit 2850 or so also but with mid 31gr. Why do you want to shoot VLDs? Compared to hybrid designs they are hard to tune and have worse BC?

    Accuracy International AT-X

    For something that extreme I'd call AINA. They or Wintac build up the chassis domestically so they will have all the small parts. And your cerakoter better be picking up the tab for that...

    .22 BRA

    Is that a new barrel or your old barrel? What was your load data last time you worked up a load? After some time away from the 22 BRA I just bought a fresh blank for the caliber.
