    That's why flatness of a fired primer is a poor indication of pressure. I tested some Winchester white box M193 a few years back for a friend. He said he was getting 3340 fps from his 20" AR. That is a bit fast. I stopped after 7 rounds as...

    vzerone Please don't misunderstand, I was not being critical at all. I was just explaining the why the psi (CUP) figures you posted were different than the psi I posted. It's like driving your car about 60 MPH, your also going about 100...

    And that's why we saw so many M1917s being used in NMC competition......the M1917s are more accurate and easier to operate, especially in the rapid fire stages than M1903s..........and if you buy that I've got a bridge for sale here in Lake...

    Previous TMs had definitions and testing procedures. Also the pressures listed are MAPs (Maximum Allowable Pressure). That is not necessarily what any lot of cartrdges is actually loaded to. Cartridges are loaded to a +/- velocity spec not to...

    Yes the pressures are listed as "psi" but they are measured via CUP method. All older published pressures taken via CUP and LUP were refered to as "psi". However, with the advent of modern and better pressure measuring methods (transducer and...

    With a bullet stuck in the throat, leade, etc. an AR bolt/carrier when drawn to the rear and released has sufficient momentum to push the next feeding bullet back into the case. I saw this many times over the years even with M193 and M855 ammo. It...

    Put them in a Tupperware container with lid. Form a small bowl out of tin foil. Put a small chunk of soaking wet sponge (water) in the tin foil. Put sliced apples, slices of oranges or whatever if you want a slight flavor to the cigars. You need...

    I velocity/pressure tested some Venezuelan CAVIM 84 7x57 about 7 - 8 years ago. I would assume it was intended to be used in their FN-49s(?). It was loaded with a 139 gr FMJBT over 45 gr of an extruded powder. Cases were CAVIM 84 lot #101-01. ...

    Did not fire out of battery or bolt and bolt carrier would have been blown to the rear. OP had a bore obstruction. Watch the sequence of events in the video. OP pulled the trigger, just a click, no bang, no recoil. OP Ejected the case and next...

    I modified a Leupold base to fit the rear sight of one of my "sportered" M91s. I put a Redfield 3X pistol scope on it. It's also D&T'd for a Lyman SME receiver sight and I modified the front base to take an M14 front sight. The Bolt handle is...

    Sometimes we have to do it. I certainly don't recommend it, but in the 300 Savage it is below the neck, same with 300 Win Mag. Sorry since I since I got my new computer...my photos are all messed up and I'm struggling with attachments. It won't load...

    "This has been an interesting read. I am flummoxed as to what this cartridge will do that a 35 Whelen IMP will not?" The 35 XCB (35x57) was designed to feed out of standard Mauser actions w/o any action modifications. The 35 Whelen IMP most...

    Only 16 and 20" barrels with no mention of twist in 308W. Might do well with some tweaking in CBA commercial rifle matches.

    "Acerbic response".......? You asked the question about Harrison 's theories being disproven. I answered honestly that if proven and reproducible it is no longer theory but fact. I also congradulated you on your own claimed ability and...
