I'm going to be reloading 9mm for my grandsons and want to be extra careful about the load. I have intended to get into powder coat but haven't yet. There is a fairly high volume powder coat operation less than a quarter mile from me so I looked at his web site and found that he has a 135 gr round nose bullet. Since I have two MP 135 gr molds that I haven't used, I thought that I would buy a quantity to reload for the grandsons. By the time these are used up I should have gotten my feet wet with PC.
The caster/powder coater had a load of 3.5 gr Bullseye on his site as a recommendation. My problem is that nowhere in the manuals is there a load for 135 gr or recommended OAL. Since we are constantly warned that seating too short can raise pressures drastically, I'm wondering if there is a method for determining safe OAL for this bullet.
I'm hoping that I can get at least one of their guns to try function with a reload before I load a large quantity. As I mentioned, I don't want to take any chances with their loads. Any help would be appreciated.
