Ran my 358 Winchester subsonic today

[n10sivern]

Haha. The ammo looks like green lipstick. NOE HP mold 280gr cast boolits powder coated over 6.5gr bullseye. 358 Winchester caliber. How temp sensitive is bullseye? It’s 40 degrees out. Just wondering if I have room to go up a little or if y’all think I should. Need to stay subsonic. It holds around 1” groups at 50 yards which I’m perfectly happy with. There was a defite thump when it struck the plywood target board. It should be a blast on hogs. Thinking maybe 7gr but I don’t want to go supersonic in warmer temps. What do the experts think?

I think I'd stay right there. 7gr might get you 1050, but I like to stay around 1000 just to be sure.

I'm waiting on my 358 to come back from the smith so I can do the same. What boolit you shooting? That's not the thumper is it? I have the thumper in an RG2, and think it weighs 295 HP.

[n10sivern]

No. Not the thumper. It was a 280gr HP that I no longer see on NOE website. I think the thumper was supposed to be 310gr wasn’t it?

[BK7saum]

Yes. The thumper is 310 or so as a solid.
