Hey all,

My summer project is to develop better loads for several calibers, namely, those above.

Mind sharing your loads and experiences with these calibers? I use the 6TCU for coyotes and the 7-30 for Antelope and Mtn Lions.

Thus far, I've used the following:

6TCU
Hornady 65s, Sierra 70 Match Kings and Sierra 80 SSPs with IMR-4895 and H335 best so far.

7-30
Nosler 120 and 140 BTips with IMR-4895 and W-748 best so far.

Your input is appreciated

Dan, this is what has worked for me in the 6mm TCU. I took a very nice 15 1/2" WY antelope with it last fall.

6mm TCU – 15”
Virgin Valley Barrel – 1 in 12” Twist

so many loads work great in 6tcu....but H335 sure is great with 80's.
from results i've had with 75gr sierra hp's over Varget in my ott 6x47, that powder may be worthy of trial in a 6tcu
benchmark, h322, and imr4198 work well and i've heard good reports on a few others as well.

IMR4198 and RL-10X do very well in my Bullberry tube. I mainly use 70gr NBT's.

Thanks for the ideas, I'll try a couple with W-748. I'll got some that laying around.
