Thread: Has anyone used 160gr TMKs in a 284?

A bit of an update. I worked up some loads I'd had some success with previously with the 162ELDMs. Once again, there was absolutely no consistency and nothing even worth talking about. You all know the gritted teeth and frustration that goes with that.
After a cool down period (of the barrel), and a few patches of hoppe's through the barrel, I fired off the 3 fowlers.
I then put the first ladder load down range with the 160TMK.
Through my ear protection I could hear the angels singing through my barrels harmonics. They all pretty much went into a slight ragged hole, with an SD of 9.
Obviously with a smile on the dial at this new found and immediate success, I fired the next few loads which opened up then closed again to a final 3 round coverleaf result. This load averaged at 2914 ft/s, with an ES of 5 and SD of 2. (3 rd group only at this stage, and no pressure signs). It was an emotional moment. I wept with the sheer joy only a handloader can know at such numbers, and I was just glad I'd worn my depends, as I might have pissed myself with excitement.

Hello Sierra 160gr TMK.

RL17, Lapua brass, Federal magnum primer, 160 tmk 10 thou off the lands. It's worth mentioning that most of the groups fired only went above 1 MOA a couple of times. So I think it's got really good potential.

It was coldish... 2 degrees. So I wonder if it would be so accurate when warmer.

The proof is always in backing it up, so I'll check back when I've fired 5 round confirmation groups... with hopeful success.
