    Let us know how your p-10 likes that load. Just ordered a CZ p-10 f and I have the no lube groove version from MP which my Walther PPQ loves. So I am curious how yours will do.

    Your solution for bullet to barrel fit is easy to solve not just with the H&G 275, but any bullet. Bullet Jump is also a big factor in getting the best accuracy.

    Since we are talking 9mm I take a sized case trimmed to .750", what I have found to be the ideal case length for accuracy. As shown in the photo make a perpendicular cut in the center of the mouth of the case using a dremel tool. Now press in the bullet just enough for it to be held in place by the tension of the case neck. Remove the barrel from your handgun, making sure your barrel and chamber are clean. Push the case w/bullet into the chamber until is seated. A 9mm headspaces on the mouth of the case. Now remove the case from the chamber. You may need a little help from a screwdriver blade as sometime it sticks a little. Assuming the bullet engaged the lands, measure the OAL of your case & bullet and to obtain the point the bullet engages the lands. Depending on the bullet design and barrel you may find the bullet has cleared the case completely, but in most cases the bullet will still be in the case. Now that you have that length you can set your seating die. Of course a bullet can only be out so far and still work in the magazine. When I find that a bullet has an excessive jump I simply seat it as long as possible and hope for the best. If you measure all your barrels using this method you will never end up with rounds that do not chamber because the bullet is seated too far out.

    Glad you like it and so easy to do, just note to how the cartridge headspaces. It not only works with pistol cartridges it works for rifles also. You do want some bullet jump, but usually the shorter the jump the better the accuracy.
