your best bet is just try them, I once had a custom rifle built the mother of all 7mm's, it was a 338 Lapua mag. necked to 7mmmith suggested a 7 twist, I asked why, he said so you can shoot the 200 gr wildcat hp's and make the chambering. Since the 200's were at that time only available from a custom maker in Canada, and the shop was a 1 man operation I said no, twist so I can shoot the good mass produced bullets, 3 months later the smith sent me some of the 200's to shoot in my rifle because a guy came in and purchased them to shoot in a 9 twist 7mm stw, and said the last ones shot great, so I tested them......sub 1" groups at 300 yards. the smith who developed the cartridge said it wouldn't shoot them with a 9, but it did.
