    ARC Mags

    I've had this issue with a Surgeon action and AICS mags... I had to open the front third of the feedlips up to about .435". That mostly solves the issue but not completely. Best to have the cutout in the action widened/deepened.

    ARC Mags

    Some of the issues people are reporting have nothing to do with the magazines. Other problems people are describing are ones these mags solved for me. I just wanted to say that I'm really happy with them and people shouldn't be scared off by this thread. Sorry you are having issues. I have no...

    ARC Mags

    I've gotta say I don't understand all the issues people are having with these mags. I've had nothing but problems with AICS and Alpha mags for the past 3 years (even after spending hours tuning the feed lips). The ARC mag I just got last week has solved every feeding issue in both of my match...

    ARC Mags

    I ordered one to see if it will feed 243AI with a 40 degree shoulder and it does so very smoothly... unlike any other mags I have tried.

    Lefty Trainer

    I'm glad I went with the CZ. I don't know what I'm missing with an Annie, but the 452 feeds 100%, the bolt to action fit is amazing, the factory barrel shoots plenty good for positional practice at 50 yards, and a $20 YoDave Trigger can make it as good as an 8oz Timney. The rifle feels nothing...

    The Anschutz custom shop website says they aren't accepting orders for the rest of the year.... I looked for a while and settled on a CZ452... anxiously awaiting someone to make a decent chassis for it...

    A few questions about the 223?

    The mag modification is a given. If you want to load within .100" of the lands and have .148 freebore like the FTR guys run, you will have a much harder time modifying them to handle over 2.500". I'm still able to load 90s past the boattail junction with a NATO reamer and fit them in the mag...

    A few questions about the 223?

    For 90 SMKs: I originally purchased a .223 reamer with 0.148 of freebore. It was way too much to feed out of an accurate magazine (2.500 is about all the OAL you will get in the mag). I think the jump was well over .100 on a fresh barrel. I ended up using a 5.56 Nato reamer which has just over...

    A few questions about the 223?

    I shoot 90 SMKs out of a 6.5 twist rock creek. People say they get away with a 7 twist, but who knows when a longer, better bullet will come along. The extra twist makes sure you're stable transonic anyway. I've had them out to 1100 with good results too and had 3 consecutive hits on a 2/3 IPSC...

    I do have to ream out donuts with a forester neck reamer every 3 firings though.

    I never measured case capacity, but 49.0 Gr of H1000 is just slightly compressed at 2.900". My brass is on its 13th firing, and Ive never had so much as a flatened primer, primer flow, loose primer pockets, or any other pressure signs.

    KC Jimmy John's Robbery

    Depends if he attacked or fled, but yes, there are at least a few states where a jury would be directed to vote guilty for shooting a fleeing robber.

    KC Jimmy John's Robbery

    A failure to feed jam sometimes just needs the slightest bump to chamber the round. You all really think being able to snatch that big ass dude's Ruger out of his hand is a better bet than just giving him the money that isn't yours?

    6slr

    I just switched to H1000 in my 243AI on my latest barrel. It should be pretty similar to the SLR. I'm at 1500 rounds. Haven't changed my load from 49 grains over a 110MK. Velocity has dropped from a peak of 3190 to 3100, but it is still going strong. I changed out my last 4 barrels after 1200...

    Hornady "Suspend" List

    This is not surprising at all, because it is just smart business. More total bullets can be made by avoiding the down time required to switch machines from one bullet to another.

    Gunsmithing Looking for a gunsmith who can profile blanks

    I have access to a bunch of "shot out" test barrels. I'd like to have a couple of them cut down a couple inches off the chamber, profiled, tapered, rethreaded, and crowned. I'm not able to do anything more than chambering myself. I know that GAP is very close to me, but I'm looking for someone...

    Range Report Books on Ballistics

    Re: Books on Ballistics Litz's Applied Exterior Ballistics For Long Range Shooting is geared toward the average shooter/hunter. As an engineer, you'll appreciate McCoy's Modern exterior Ballistics much more.

    Building an M-110 type service rifle

    Re: Building an M-110 type service rifle Thanks, but the Krieger website is what originally got my little project going....I've done a a couple hours of research, but just can't seem to find any details. Thanks though.
