    Hornady 76g a tip

    We did the 62gr ELD-VT for the 22 ARC and there's a pile of angry people because it's not magazine capable in 5.56 AR-15's. Do a 76gr A-tip that fits the AR-15 and people are angry it's not a higher BC. :) I get it. I designed this one and did what I could to get BC up there but you're stuck...

    Hornadys new ELD VT

    It's going to be barrel-to-barrel dependent. I pretty much seat everything at .020-.060 if I can and don't mess with seating depth. I have seen a few instances where it made a significant difference but in most of my barrels that I've tested it I don't see dramatic swings in performance. I've...

    Hornadys new ELD VT

    In .308? H4895 (if you have or can find it), Varget, or StaBall Match would be my first three tries. I'm sure IMR 4895 and 4064 are worth looking at, too. I doubt we'll do a factory .308 load because it'd end up being over SAAMI max COAL. I'm pushing for it to replace the 168 Amax in our M1...

    Hornadys new ELD VT

    Yeah that's a known issue should be fixed going forward. Typo. I don't remember off hand which is correct but just off the fact that G7 is usually half G1 it's probably .226.

    The Cartridge Conundrum

    From 22 to 7mm... Maybe 6.5mm... You can't really go wrong. If you can get over 2600fps and a bullet with a G7 BC in the .260+ ballpark (give or take any of that) it's on a sliding scale of trajectory and wind drift and the deciding factor is usually the shooter and their ability to perceive...

    The Cartridge Conundrum

    I've been shooting 6 ARC in a bolt gun for several years now. It does everything the Dasher/BR family does with less powder and less recoil. I got 2nd place in gas gun PRS last year for the season and have a few top 10 and several top 20 finishes in Open with a bolt gun. The cartridge isn't...

    Replicate Hornady American Gunner 6.5 Creedmoor 140 grain BTHP

    H4350 or Hybrid 100v I believe were the two main powders used in that load.

    6mm Arc Build Questions

    I have a 16" build that I'm pretty happy with as a hunting/beater rifle, Aero upper (no F/A but do whatever makes you happy) Aero M4e1 lower Aero handguard Faxon Match 6mm ARC 16" barrel (YMMV, I think I got lucky with this one it hammers with factory ammo, I know Faxon doesn't always deliver...

    Key holing 6mm creed after barrel cut

    We've done a lot of by-the-inch cutdown tests and we bandsaw the barrel then hit it with a chamfer/deburr tool from the reloading bench. Never seen issues with stability or keyholing in doing that. HOWEVER, we do have slow-motion footage of some sub-X's getting some pretty impressive angle of...

    Help identifying a factory 2nd bullet.

    It's from an OEM run of what are basically 105 Amax's (non heat shield tip daddy to the 108 eld-m).

    Barrel too hot?

    There is no real concrete data on this because there are so many variables at play... This is just my experience/opinion. In general small stuff like .223 or the ARC/Grendel family I've never seen anything cause groups to open up in 1.20" contour barrels as much as 40 round strings. I never...

    Density Altitude

    DA is a quick reference for subsonic aviation and supersonic ballistics is more driven by Mach/Reynolds number, so you can find inconsistencies in some cases using DA.... But, for your question, -2000 to 8000 should cover most situations. Every 1000-2000ft out to 600-800yd should be close...

    The Sportsman Division

    The issue here isn't divisions. It's classifications. I'm of the opinion that they mean very little currently, and they should be made to have more a distinction/use in separating classes of shooters and promoting both recruiting of new shooters as well as skill development. JMHO.

    How many loads did YOUR last batch of brass last YOU?

    Yeah I'm mostly joking. If you're getting case head separation it's not usually a pressure thing, more of a stretch/resize thing. Guys that blast Lapua/Alpha primer pockets in 5-8 firings though... It's pressure.

    Weight ES for LR bullets ?

    I've done some testing with this and the example that I did the biggest test with was 6mm 109 ELD-Ms. I weight sorted through 1200 of them to get 30x each of the "high" and "low" brackets. Low was 108.7gr, high was 109.2gr. The high and low MV separation on 30x ea. was less than 1fps on the...
