RE: barnes triple shock x
IMR 4831 or H4831SC in a .270 Win with the 130gr offering.As advised start low,contact Barnes for data and remember a pure copper bullet is going to have a longer bearing surface than a lead cored bullet.This will nessecitate deeper seating taking away some case capacity.My Win FWT Classic doesn't care what powder as long as the 130 slugs are doing around 3000fps it's MOA.Had good results with Win 760 and mag primers.........................Harold
