The seater stem in the foster micro seater is very very soft. It says it in the instructions to not use it for loads anytime their is powder compression. I learned from first hand experience.
You need a diffrent powder if you have h4895 that would help but it to is a bit bulky for loads that short. Varget will work and produce great velocity's if you can load them out very long like in the 2.390 to 2.4 load length range anything at 2.300 are shorter is going to compress with heavy bullets and varget in the grendel case.
Edit to add.
You could try a 9 or 12 inch drop tube. But I dont think that's going to be enough help. Your better off trying a diffrent powder.
It's Redding that says NOT to use their micrometer seating dies with compressed loads, not Forster. As to "grossly over compressed", why didn't ANY of my load data sources show the Varget load as compressed, even at max? Ya'll might want to go back and review some of your own information
.More info, max charge was 27.5 gr., brass was new Starline. I used exactly the same charge weights with the Hornady ELD-M's with no issues. I do have some other powders on hand, although H4895 isn't one of them. Like I said in my OP, I won't be wasting any more time or resources on the TMK's, I was just curious what went wrong. Later.
