Hey guys, I've just purchased 2nd hand zastava m70 in 7 x57. I will be using the rifle for hunting fallow,reds and pigs.shots would range from close say10-20m to max 150m. What is a good bullet weight and type/ brand. I'm thinking on the heavier side say160 and up, I already have a 6.5 swede running 140g SST's. i have win 760 powder, is it a good powder for the 7x57 or is their a better choice?
