Some reloading guides say it(105gr) maxs out at 2800(out of 24-26) and thats more the speed you might get from a 243 wssm . I would say thats too hot for most stamdard 243 in 20"", esp if its got a low twist rate

I don't think that you reload, do you?

3k easy peasy. The high energy powders like N550, R17, V100 do it in a breeze. Good cases like Lapua or Norma assist.

My 20" 234 is 3,270 fps with 85 grn Interbond and V100, and 95 grn Targex 3,080 with N550. No pressure signs.

The Lapua reloading data has 100 grn at over 3k with N550.

I'm not aware of any correlation between twist and pressure, but might be wrong.
