Sierra Heavy TMK 6MM Testing

[TxLite]

With that said, they just aren’t quite stacking like the Berger’s, so I’m going to sell my remaining lot of 107’s and wait for the 116’s.

This has been my experience with sierras as well. Generally accurate enough just not quite as easy to find a good load as the bergers. Though I haven’t tried any of the new offerings

I did a little testing with the 107 in a 22" 6 Dasher today with Varget to get an idea of speed and if I'd hit pressure. Loaded COAL 2.450". Didn't have any signs of pressure, will likely load some hotter to further test

What brass are you using? I'm planning on using 107's with my 18" Dasher & Varget. Curious how much more you are able to get out of them velocity wise as well.
