The 130 TMK has been around a while. I bought a bunch of them when they first came out. They are extremely accurate but a pig. Great for shorter distances but dont fly like 130 or 140 Hybrids past 600yds.
The new 130 SMK is a sleaker, longer, skinnier, pointed 130 so the higher BC makes perfect sense. Different bullet design. These have already been well proven in the Prime US made ammo for some time now. Just now being released in bullet form to us reloaders.
I've had a 1000rd box of them for a few months now but with the holidays, the flu and being slammed at work I didnt get a chance to test them till this past week. SD's of 2 and 3 across many charge weights from 37.3gr - 38.1gr Varget in 5x Lapua brass with CCI 450 out of my 26" 6.5x47L Kreiger.
Accuracy was not the right seating depth, as I loaded them at .01 off the lands. I have a good feeling after this OCW they like to jump like every other SMK. Got the OCW re-loaded back up at .02 off lands. Very consistent 4 shots in a hole and 1 shot below the group with every charge weight tells me it doesnt like that seating depth. Still 0.5" groups
Stay tuned but here are the numbers.
37.3gr - 2915 SD4
37.5gr - 2916 SD9
37.7gr - 2940 SD2
37.9gr - 2948 SD3
38.1gr - 2954 SD2
