    The title says it. Wondering if anyone has tried to PP 270 cal j-words for use in the 7x57? If so how did it work out?

    Lots of people have patched up jacketed bullets to shoot in a larger bore rifle when they couldn't get bullets of that size. If you try roughen the jackets of the 270 bullets between two files by rolling them back and forth between the files. It gives the paper something to hold on to. Without that roughening the bullet tends to squirt out of the paper jacket and accuracy is nill. Brodie

    Yes.
    Exactly as old coot said.
    Roughen up the bearing surface so the patch will stick to it.

    I have done a 308 to 314 for a 303 Brit, shot a couple of decent groups just to see if it would work. As Old Coot says roughen up the jacket. I also used a light wax or lube and let the patch just go over the ogive. Also expand the neck and bell the case mouth as you would do for cast.
