    Proof Research 22ARC barrel issues

    ~200-250 rounds on my 18" Proof. Might be something to it. I am not one to chase speed and tend to think the 22 ARC is about as much powder as one should put behind a .224" bullet, especially with 1:7" twist... Be curious to learn more about this.

    Suppressors 338ARC AR can choice: 9mm or 338?

    What do you mean by "better"? Noise levels I'd say are similar. Still burning 10-12gr of powder. It's obviously very dependent on the suppressor used but IME something like the TBAC Fly 9 on a 338 ARC is as quiet as most .30 cal (6-7" or longer) cans on a .300 blk. The Fly 9 in short mode is...

    Did Hornady Change 147 ELD-M Bullet?

    It's been several years, about the time of A-Tip release. We kept it quiet while the patent process went through. The only changes to the 147 I can see was the cup that was used, which affected overall length (Both OAL's in his post are from after that change, it was done relatively early in...

    Did Hornady Change 147 ELD-M Bullet?

    There was a change made across the board with ELD-X, ELD-M, CX, and ELD-VT to reduce drag variability. It was simply tip geometry. What Brian Litz saw and posted is 3rd party confirmation that DVRT works. The way our SKU system works, there is zero difference between 26333B (or any other...

    6 ARC Longevity

    Grendel was selling about 10:1 over 6.8 SPC around the time the 6 ARC was introduced. 6 ARC outsells Grendel by quite a bit. I think it's here for a while.

    Hornady 4DOF ZERO Angle

    I'll have to double check but I'm pretty certain you can use ZA in the 4DoF Kestrel. It is often easier to figure out what the value is in the app, then feed the info through Kestrel Link.

    Hornady 4DOF ZERO Angle

    After you do that, you can verify by putting in 100yd, no wind and see what correction it tells you. In this case it says to impact perfectly dead center you need .06 mils (.22" at 100yd) up and right. So this minor deviation in 100yd "zero" will carry through in every down-range calculation...

    Hornady 4DOF ZERO Angle

    Based off of your target, here's the inputs in 4dof to find your zero angle. The rest of the stuff above this is unique to your load/rifle and I have generic sea level environment.

    Hornady 4DOF ZERO Angle

    When you use "Zero Range", you tell the app that you are perfectly zeroed at 100yd (or whatever distance you put in). This forces the solution to cross elevation= 0 at whatever distance you put in. Simple enough. However, most of the time, if you were to lay down and shoot at 100yd, you would...

    Hornady Lot to lot. 200fps difference?

    Sorry, forgot about this thread. If you pull one I'd be curious if it's 38.3ish gr of a ball powder or 36.5ish grains. Looking at the lot data there was some initial set up that was fast but still under SAAMI MAP in our P&V test barrel and they dropped powder charge to get closer to the...

    Swiss ZK31 Israeli sniper rifle.

    Sometimes the hype campaign and/or "fuck you" money works. I remember watching a very nice ZFK55 go for north of $8,000 a couple years back. It was a very clean example but the price was entirely unjustifiable as far as I am aware. Serial number was run of the mill, just an excellent...

    M1917 vs M1903

    The stock and butt of the M1917 punishes me a lot less than the M1903, especially prone. I don't know what it is about the m1903 but it's brutal. Mausers, K31's, M1917's, M1's, etc.. all are fine, if not pleasurable to shoot, but the M1903 is just a bastard to my shoulder. I really like the...

    Plane crash At Reagan National

    Understand that I'm speaking from a position of a flight-sim nerd, not an actual pilot and I'm not familiar with exactly what was in the Blackhawk in quesiton... BUT, flying something like an OH-58 in DCS using the MMS FLIR on the MFD's on the dash at night without NVG's is disorienting as...

    Hornady Lot to lot. 200fps difference?

    No, GAP doesn't load them. We loaded it with the GAP headstamp and sold it to GAP as the sole source for distribution. I believe that changed this year or last year and now it's a standard Hornady SKU that's available through all of our distributors. If you have concerns with that particular...

    Hornady Lot to lot. 200fps difference?

    That's the item/SKU number. The GA suffix is for GA Precision when it was an exclusive deal through them. Lot number will be around the corner on the other side of the box.

    Thread existing barrel or buy new

    You still have 2000+ rounds of barrel life in that barrel. Does it shoot well enough to keep you happy for 2000+ more rounds is the real question. If yes, then thread away, if no, save up and put a top tier pipe on the rifle.
