Re: TUBB Final Finish
After speaking with rep from IMR/Hodgdon/Winchester powders, they could not confirm that IMR 4227 was a safe load. I then once again called TUBB and spoke with them about how critical velocity was, and their reply was that the slower, the better. They suggested using IMR Trail Boss and filling the cartridge to the shoulder. IMR confirms that this is acceptable.
I bought a can of Trail Boss, and loaded the first ten rounds with 23.0 gr. The case will hold just over 24 gr when filled to the bottom of the neck.
I went to the range twice this week after work, and fired 5 rounds each day, cleaning thoroughly between each round. Now I'm ready to load the second group of bullets, and do it all again.
