Big girl in the snow! @tom targets made me try another powder. Roughing it in with course powder node and rough seating. Target shot at a grand.

@tom @Alex Wheeler sizing questions

i Am assume alex made a FL die for this cartridge from JGS, how much are you sizing the base and shoulder OD? .003 ? Have you tried other amounts to see accuracy differences?

With this harder brass you have to struggle just to get it sized enough. Theres no wiggle room to play around in. I have made all the dies so far but I had Hornady run a batch for me that will be here this week.

That’s the load I shoot with 200.20x. But I use 215M primers.

Big girl in the cold. Ran seating a little. Gun looks happy with 209gr vapor in lands. Will wait for warmer Temps to refine powder.

Are those 209s an older bullet style? I have some 204s to try and didn’t see there was a 209 also.

Yes older lot with a thicker jacket I am told. Newer lots are 204s I believe.

5 degrees warmer than yesterday, but I'm on my way none the less.




Hopefully it straightens up a bit here while I'm down south.
