Had a couple questions about reloading for 7.5x55 Swiss, since I'm going to purchase a rifle chambered in it. My intent is to shoot this at longer ranges, in excess of 500 meters.

• I'm undecided between the 1911 rifle and the K31. From my understanding, the 1911 has a weaker receiver than the K31, while the K31 has a shorter throat and requires bullets to be seated deeper. I know both weapons can shoot GP11. However, for reloading, will the weaker receiver of the 1911 mean I can't shoot as powerful a load as the K31? And with the shorter throat of the K31, will I have to reduce powder to accommodate the deeper seating of the bullet, thereby reducing muzzle velocity?

• Is there a particular reloading manual you recommend specifically for this cartridge? Both the Hornady and Berger manuals I looked at had loads, Sierra and Lyman's did not.

• What powders and bullets have you found to be most effective at longer ranges? I'll be using PPU once-fired brass.
