    [DO NOT TRY THIS EXPERIMENT IN ANY WAY SHAPE OR FORM- this test was conducted with hands-on help from world-class experts]
    A lot of you have missed the point of this video: This is a SCIENTIFIC TEST to demonstrate a few things:
    1. The increased pressure capacity that Alpha Munitions brass can handle
    2. The amazing strength of Bat actions, see czcams.com/video/VkvFtlTEuSc/video.html for more info
    3. The IMPORTANT relationship between chamber, brass, and resizing die - see in-depth video here: czcams.com/video/5oOdQbDq1kE/video.html
    This is NOT a suggestion that 308 Winchester can replace a 300 Win Mag.
    [[[We got within 98.2% of Nosler's 300WM Max data]]] Here's the math: Nosler lists 10 powders/loads for 300WM 210 grain (average max load = 2807.8 fps), and 10 powders/loads for 300WM 220 grain (average max load = 2700.3 fps). The middle ground (215gr equivalent) between these is 2754.05 fps. We achieved 2706.3 here with 308, so that's 98.2% of what Nosler lists as equivalent 300WM max performance for a 215 grain bullet.

      That's Noslers load data. You don't think you could push beyond that? Hard to believe you couldn't get more out of the 300 WM with a higher chamber pressure and larger case capacity. Would've been a cool video. Anyway, keep it up.

    This is a great video on the subject of pressure signs and how they don’t equate to max load/ max pressure. I’ve used book listed velocity as a stopping point for 30 years for this reason.
    That said, whether intentional or by accident, this may be the best advertisement for Alpha brass ever created.

      Issue is, modern cartridges like the 308 and many of the most modern are quite straight in the body and that reduces the visible signs of pressure compared to older more "vedge" shaped..

    • @mfallen6894
      @mfallen6894 Před 3 měsíci +1

      @@jmkhenka The case taper? Yeah, .308 has much less taper than, say, a .22-250. I just found an old .22-250 round in one of my really old rifle cases (must have been my dad's as he had a .22-250) and I was comparing it with .308. First time I remember looking at a .22-250 and it seemed like there was a lot of room to blow the walls out straighter, use a sharper shoulder, and you could probably get a lot better performance... Though you'd probably want to run heavier pills/larger caliber so that it doesn't kill barrels even quicker!
      Totally off-topic but as I was comparing the two I was thinking "why doesn't the military use a case this size" as they've been wanting to go back to short-action instead of intermediate. Seems like you could get better velo's creating a round with a COAL between the 5.56 and 7.62 NATO, Like a 2.5-2.6in COAL, with a powder reservoir in the middle of the two. I guess it's probably due to standardization of box magazine sizes and splitting the difference would require an entirely new magazine design.
      But yeah, like a ".223 rem mag" or a ".7mm-08 special" , but not just adding/subtracting length, having the case head diameter split the difference as well. Get better velocities, flatter trajectory, longer effective ranges than an intermediate, while saving some weight and having less recoil than with a .243/6.5CM/.308. But maybe people have already tried it and the gains wouldn't warrant the cost of development...
      Don't mind me, I'm just thinking to myself, lol

    Key insights:
    1.) Case head pressure signs are depended on the type of primer, brass, and bolt face.
    2.) A case failure will most likely ruin your action and could injure you.
    3.) With strong brass, case head pressure signs don't appear until you are well over SAAMI levels.
    4.) Alpha brass w/ SRP is tough stuff.
    I would love to see you test brass life w/ the 44.0 charge (did not show extractor swipe and estimated 80kpsi)
    Make wise decisions people....

    • @paulm749

      At the risk of sounding like Captain Obvious here are a few more factors to consider about this exercise:
      1.a) Precision reloading equipment, instruments and techniques to match the loaded round as close as possible to a specific action and chamber.
      2.a) A high quality action mated to a barrel chambered by a very competent smith. Everything about this rifle and the ammo is TOP QUALITY.
      Bottom line: You wouldn't shoot this ammo in any other rifle because this load development is very specific to this one single rifle. Don't try this with a mass produced off-the-shelf rifle that by design has much looser tolerances - that's why we have SAAMI specs.

I proceeded to work up to their max charge weight and lo and behold my 20” .308 was achieving 24” 30-06 velocities with 165 gr bullets. Unfortunately the brass no longer retained the spent primers and thus ended my high performance 308 loads. This was either Winchester or Remington brass: I was content to load the 308 as a 308

    I have done certain experiments I won't detail here, but this confirms my thoughts and observations from results I have gotten. To get more out of a cartridge, the brass needs to be tougher to handle higher pressures. With such brass, cartridges can be more efficient with powder to velocity. Interesting to see if we can redefine the limits of our cartridges with better brass.

      Wait what, 3 piece process? I assume you didn't mean the brass isn't made up from 3 individual pieces, right? You're talking about 3 brass forming procedures? Because I always though brass (or aluminium and steel) casings were made from a single piece, first a disc is punched out of a strip of brass, which is then progressively stretched, cut to length and necked?

      Quite a Few years ago, I Bought 500 Rounds of some .300 Win Mag ammo from someone online. The ammo was Factory Loads and the Boxes were the White Cardboard like you can get from Midway with labels that had all of the Load data. The OAL and Powder Charge (IMR 4350) were well over anything I could find in any Reloading Data. So I contacted Federal and asked them if the ammo was safe to use. They told me that the ammo I had was Custom loaded for the US Navy's Long Range Competition and I should NOT shoot them in any Commercial Rifles. So I took the rounds apart and reloaded them to a "Safe" Charge weight and OAL. I still haven't shot any of them yet, LOL!

      Before your panties get too wadded up, consider that the same basic receivers are used for .338 lapuas as .300 win mags and .308s. .700" bolt bodies and 2 lugs is very very common. The thrust from a .308 case vs a Lapua case makes the receiver very overbuilt for .308 or marginal for .338 Lapua, but no one gets bent over Lapua loads that are inherently more dangerous.

    This is a great video which highlights what i have heard about small primer pocket brass; you can shoot much hotter loads than with standard large primer pocket brass. I have small primer pocket alpha brass for 25 CM, 6 dasher and small primer pocket lapua for a 308 and small primer pocket for a 6 CM. Have you tested lapua or peterson to over 80k psi? Also when i see many "pet hot loads" on forums, your video proves what i assumed: most of these loads are substantially over 60k psi. Many are likely 65 to 70k but my experience is that most large rifle pocket brass will have loose pockets in 2 to 3 firings with high pressure loads, even with no stiff bolt lift, no extra case expansion at the web and minimal plunger/ejector marks.
    I have Gordon's reloading tool on my laptop which is similar to your computer program but mostly i load based on years of knowledge, powder burn rates, good load data, always using a chronograph, watching cases and primers; it's apparent from your test that high quality brass like Alpha, will not show tyoical pressure signs until the load is Waaayyy over max. It seens that loading to 70 to 75k psi with quality small primer pocket brass is "safe" and 60 to 65k psi with large primer brass is safe. For long term primer pocket life in normal brass, 55 to 60k range is probably ideal.
    Thank you again for producing quality vids with informative and in depth tests.
