lapua scenar 155g

[fclassNrugby]

Doing load development on 308 155 lapua scenar with 2208. Lapua palma brass CCI primer.

Any tips or load data anyone cares to share?

Yes, I've been testing the 155 Scenar (and their 185) in my FTR rifle.

10T 31 inch barrel, 46.4 gr 2208 produced average velocity of 2990 fps with 16 thou jump. Palma case Fed 205M primer.

COAL at touch is 2.876 in my chamber.

The 155 Scenar has a longer bearing surface compared to Berger/Sierra so pressure builds up a bit quicker for a given load.

Thanks NDO, going to do a ladder test 45.2gr to 46.8gr (increments of 2) to find a node.
will seat them at your 16tho jump for the velocity node finding test.

Will post my findings back here.

yup on the money 46.4 gr 2208 best node and average 2987 fps. Will now play with seating depth for groups.

Thats exactly the load I use with my 308 and 155 sierras

OK my rifle likes 0 tho and 30 tho, so either in the Lans/lands/lanse.......... or a bit of a jump.
