6.5 Creedmoor/260 for Deer, Elk, and whatever else.....

I've had great terminal results with both the 147 ELDM and the 129 SST out of an 18" sig cross.

The 129 SSTs velocity is impressive out of the 18" barrel, I get 2825 fps from the superformance 129s and only 2475 fps out of the 147 ELDMs. All factory ammo.
Same experience with my 18" Bergara, Superformance 129's was 2821 average and 2544 average for the factory 147's.
 
153 TMK now available
I already have a box. Limited experience entering projectiles into GRT but I think i did okay with it. My calculations thus far say I should be able to get 2600fps out of my 18” 6.5x55 and stay under 62k PSI with norma MRP (which is essentially RL22).

I’ll hopefully have some load/velocity data at the end of the month when my new powder dropper gets in off of back order (old one broke and was warranteed).
