Thread: .223 77 grain TMK

Just wondering what people are loading for this?

I am currently using 20.8 grain of 2208, it is a little underwhelming. Tikka 21" 1:8.

I am pretty sure they can fly better, hence the question.

I load them with 2206H in a Tikka and Sako around 24.4grn but I would start at 24 and go up .1 or .2 at a time

24 grains is warm in my latest rifle. I would start at 22 or 22 but yes it's a good combo.

Yeah, work up but 24.4 2206 is a go to load for Tikkas.

You're nearly 3 full grains under Hodgdon's maximum load for a 77gr SMK and Varget (same powder).

No wonder it is underwhelming

Yeah, this is true, I had no chrony at the time and just took the best accuracy load from a workup.

I love how the best powder is the one I never have Might be some 2206H on the way then......

I'm using Benchmark 2 with 75gr bullets in my 223, was considerably faster than 2208.
BM2, BM 8208XBR, or 2206H are probably your best options (for ADI powders at least).

I do have some BM2, what sort of loads were you running? I will work up, just a ballpark so I don't have to cover 3 grains in .3 grain increments

I use 25.0 and 25.5 of 2208 behind a Barnes 80.5 gn .224 pill so you can be a bit braver. Seated out long though.

Cool, I have a bit of 2208. I will work up to that and see how it looks I think I have only ever loaded up to the Sierra book max, 22.1 or some such, may find a node above that though.

Helpful having a chrony now though Thanks for your input

23.8gr of BM2 is doing 2750fps with 75gr BTHPs in my 18" 223.
Seated long as using CTR mags.
