    Good work, Dan.
    You are going to need all the practice you can get if you are going to beat the Golden Greek from WA... at the Nats.
    Hope to catch up with you there and have a yarn.

    I'm shooting Open in Pensioner Div.
    Hooroo.

    If you lug those buckets around too much you wont be able to shoot while in traction. Regards Stephen

    I'm ready for grooveless moulds. When I think of what's going on when a bullet starts moving in the beginning, the case neck is expanding to (often oversize) chamber dimensions... I see more of a possible sealing problem with a grooved bullet. Without grooves the bullet is also stronger to take all that pressure from behind.

    Just thinking.

    Another advantage with grooveless is contact surface with the barrel.
    While I work at it, it is by God's grace that it happens..

    Look at 31-165C for the proper way to do grooveless rifle moulds. 100yds, 2100 fps 145gr PB from 300BO AR carbine. Believe the 'spread' is from gas port base cutting.

    ****, have fun moving those buckets. When i dump mine into buckets, i work out where i want them to stay and fill them. I'm not going to even attempt to move a bucket with 120kg of lead in it.

    HAHAHAHA

    I don't know him very well, but from the chats we have had on the phone, i can see him doing that

    As long as he is on the mend, being sick sucks, being REALLY sick is far worse. Hopefully he doesn't whine too much to the nurses, they administer drugs, they know how to use NEEDLES. My mother in-law was a nurse, i have heard stories of what she used to do to unruly patients

    Looking good.

    I have figured that the bigger caliber I cast for,the more money I save.

    That is very impressive Popper.
    What sort of ammo is normally used in such a gun?
    Were these all just cast coated with Hi-Tek?
    Would you get such accuracy with other ammo as well?
    If you had some gas cutting. I am thinking that may be a dip of end into coating mix,( after successful 2 coats), can supply essentially a third coat at tail end, where heat needs to be reflected.
    It seems, that the very high energy of load, you may need extra heat reflectance benefits. The coatings should give you some.
    Great test for comparison to see what happens.

    Joe, those were PC not hitek. I did try the hitek trick on the base but just used BLL (alox) on the boolits for that test. Didn't work or at least not conclusive. Haven't been able to shoot anything for a couple months, darned rain (flooded the range shack to the rafters - supposed to be open for pistol today, maybe), want to go tomorrow but cold & rainy again.
    You can load BO from 100gr to 240gr, very versatile case. I've got 168 GC and 185 GC Hitek'd to test in the 10" with soft alloy for pigs to test. The 145PB is for longer range from the carbine. That target show base damage, tested for that years ago in 40SW - cut a notch in the base and get a 'ring' of shots on target.
