I am hoping somewhere about 55,000 - 58,000 psi and its producing a sub-1/4 MOA load.... That would be nice.

Ya, that would be nice.

The tip of the ZA has been flattened by my gunsmith to prevent injury...as when I shook it out of the box it hit my palm point first and drew blood...nasty and TRUE.

    Here she is on the left, next to the 7WSM and 284 Winchester (with 180 Berger's seated to their shooting length in my 7WSM and my brother's .284 Winchester.. On the left is a piece of new 338LM brass and a blow-out case to my improved ramer design.

    The 338 total length is right at 4.135 inches



    Jeffvn
    That 338L AI is a kick ass looking cartridge,Jeff.I'm glad the wait is finally over for you. !!!

    LOL,If you need some help breaking that thing in give me a buzz.

    Steve

    Thanks for the response I may take you up on that so that I can show you my spot in the desert. I took possession of the rifle on Saturday. This is what she looks like. Manners T2-A in Coyote Brown, Barnard PL 338 single-shot action, 32" tube, March 6-60X scope w/ ranging reticle, and a removable Badger FTE break....so that I can thread on the AAC Titan Supressor that is on order for it.... :-D. The rounds shown with it are the 338 LM Improved with 7 Caliber ZA, my 7WSM with Berger 180, and a .308 with 170 Lapua Lockbase.

    I've not had it to the range as yet, and hope to start load development as soon as possible on the ZX 7 CAliber bullets and then on the GS Custom 295 after that.

    Yeah....That's sweet Jeff !!!!! I bet your excited ,for sure.

    You'll probably see more than half the wind drift compared to your 7WSM ?!?!

    At what distance do you think it'll go subsonic with those Z7's?

    Re: Future H.A.T B.C. Test shoot

    I have no idea, as the BC is unknown; but if its only 1.00 as a G-1 then we'll be looking at subsonic transition at around 2,500 yards acording to the JBM calculator that I just ran it on. The inputs that I used were BC of 1.00, weight of 300 grains, altitude 2,200 ft, temp 75 degerees, humidity 20%, pressure 29.92 in Hg., velocity 2,950 fps.

    The other numbers are just scary low as far as wind drift and elevation to reach distances...but I'll save the speculation until after I get a chance to test this rig.

    Really rough I know, but its using the velocity that I am planning on and the rest are accurate paramaters from the range where it will be tested. Obviously, the range is reduced at seal elvel.

    One can safely say Dayum...if that turns out to be accurate.

    One thing I can tell you. I can and will get some good data from my home range at Boulder Rifle and pistol club. If she is shooting well, I'll get muzzel as well as some intermediate velocities from 500 meters and possibly 900 yards; plus the required elevation in MOA from my 100 yard zero to each. We can back out some BC information from that information.

    Steve...email me and we talk about dates for a desert visit when this is up and running...maybe you bring your .375 and we'll hammer some steel out to 3,000 ..

    Jeff,

    Forgive me if this had been asked already, as I don't recall, but would you measure the ogive, bearing surface and boatail lengths on that Z7 rocket for us? Perhaps a pic of it by itself next to a 300SMK or something in comparison? I wonder how close the dimensions are to the new Berger Hybrid, now that we have some solid bc numbers on that--might give us a better comparison.

    Jon
