130 TMK and 260 REM

[BH30-06]

Hey guys,
I’ve been playing around with the 130 Berger hybrids and have been getting pretty good accuracy out of them. I bought some 130 TMKs and was wondering what has been working for you, I have h4350, CCI br2’s, and new Lapua brass.
Thanks

Winchester 243 necked up to 260.
CCI#200
IMR4451
Loaded at 2.84 for AI mags which is a LOT of jump in my chamber.

43 to 46.5 grains with the top getting me 2940 with no pressure signs yet.

Every load looked good and I need to go back and try to pick a load and adjust seating depth.

They seem to be like 142smk’s in that they’re easy to load for.

I use H4350 and 4451 interchangeably but I can push 4451 a bit harder.

In lapua brass I’d subtract at least 2 grains because of case volume difference.

Thanks, what’s the barrel length on your rifle.
