I bought a bag of Frontier 110 gr plated bullets to load until I get some cast up and sized. It has been 20 years since I loaded any carbine rounds last. Looks like I will need to seat these a little deeper than normal to get them to chamber. I seated to 1.68 and the bullet still hits the rifling. Bolt wont close all the way. I am afraid now to seat deeper and worried about the pressure. I dont like these things. Anyone have any experience with these?
