i couldnt get the hornady fpb in 350grns into my barrell at all.... damaged the copper jacket trying to get it started?????????
When I load the FPB's the trick I use is, set the bullet over the muzzle. Be sure to center it as best you can. With your short starter, give that thing a very sharp rap with the heel of your hand. You want to drive that into the bore. Once in, it will move down the bore in a solid manner but will move down the bore.
