I guess that means you tried it and it did not work.

I personally would NOT try to make that combination work...TB is a great powder for lightweight single-shot subs, but not heavies...which is GREAT, because 110s-125s are waaaay cheaper than most 220s...be careful, and have fun! However I have about 4K combined 220s, 190s and Berger 230s on the shelf.

That is exactly why I am asking.

Anyone have any experience with 220 Sierras or 230 Bergers and TrailBoss?

I was wanting to try some through my bolt gun and cant find any data anywhere. Lots for 1680 and N-110, but no TB.

It works excellent in 308 under 175s. Incredibly quiet and accurate.

Issues like these (and too many others in the past to count) and people still order stuff from this guy. I dont get it.

Hornady One Shot.

Tumble in corn cob after loading.

Now that my PSR is here I dont really have a need for two 338s in the safe. 2011 AX, 338 Lapua. 387 rounds through barrel. 5 total mags. SAS Brake. Lucas bore guide. Scope and bi-pod not included. Not looking for any trades other than S&B Optics. $6000 shipped. http://i890.photobucket.com/albums...

I am using a Hahn block and Colt mags.

The bolt is a ramped CMMG. The upper started out as a 16 inch Rock River upper, now it is just over 5 inches long.

The lower is a Colt M-16A1 RR.

Standard weight buffer and Geissele trigger.

Using 160gn plated bullets and TG powder, it is incredibly quiet.

I have reloaded lots and lots of 300 Whisper/Blackout. I have yet to split a case neck.

Where the new neck and shoulder is located is where the original annealing zone was.

I annealed a few batches here and there just because I had a new Giraud machine to play with. It did not seem to hurt/help.
