Okay thanks everyone for the input I'll see what I can squeeze out of this 20 inch barrel that I've been messing around with

How much jump and which TMK? Sorry to derail

I never measured it but achieved it through testing. Since I only shoot the Sierra Tipped it didn't really matter. seems like that bullet is not as sensitive as some.

I run 190s, 200s and 208s. H4350, VVN540, 550, RL17 are top choices for the heavies. Get a Wyatt extended box to seat them long. The palma case has slightly better volume than the Lapua LR cases. With a 27" 10x barrel I get 2650-2700 with 200 Hybrids and H4350. YMMV

Michael I used RL17 and got great results with both 200s and 208s but Alliant powders have gone extinct. I use a lot of N570 in my magnum calibers but haven't tried N540 or N550. In you opinion which of the two would be best for 208s and how would it compare it to H4350 as far as accuracy and temp stability? Thank you in advance for the info.
