Once I got the right sized bullet for that barrel it did nickel sized groups for the next 4000 rounds.

I haven't tried that size on my 7x12, yet... 6-48's worked though. :) While I do use that 0-80 size frequently, I do it with commercial screws, taps and dies. However I have made quite a few 1/4-28 threads using G76. For #209M nipples for one of my BP rifles. Non-vented for use with Blackhorn 209 powder, which takes a tactical nuke to ignite it. Its very accurate stuff, IF you can get it lit. A #11 cap won't, and a vented 209 nipple won't, it takes the full power of a 209M shotgun primer in an unvented nipple to do it. Also quite expensive at $4 an oz in 10 oz containers. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
