These excellent guns are basically built around a single cartridge: the Winchester silver tip hollow point. That's what they're tuned for, and that's what Seecamp recommends you shoot in them. I couldn't locate an silver tips locally, so I bought a box of UMC 71 grain FMJ rounds and decided to see what would happen. The first thing that happened (or more correctly, didn't happen) was the inability of the rounds to be loaded into the gun's magazine. They were too long, and would not fit. It dawned on me that the silver tips are 60 grain bullets, and I theorized that the 11 grain difference in bullet weight - or more precisely, the accompanying increase in bullet length - was the real culprit behind the ammunition limitation.
I should point out here that I'm perfectly happy to load my Seecamp with silver tips and carry it that way. By this point, the question had become just a "can it be done" sort of thing that shooters sometimes indulge in. There was nothing really to gain from taking this any further except information, and maybe a little bit of satisfaction.
With that understanding, I did a little experimenting. I found that my gun will function perfectly with the heavier bullets - no problem. I went along like this for a while, because the cheaper factory ammo is almost invariably 71 grain. I just didn't feel like spending nearly a dollar a round to shoot my Seecamp. So, I took the part out of the magazine before each trip to the range, then put it back in.
I am a long time reloader, but I never seriously considered reloading .32 ACP because the Seecamp is my only gun in that caliber, and I just don't shoot it enough to justify keeping an inventory of the additional components. By pure chance, I found a deal on a good set of Hornady dies, and bought them in case I wanted to start loading .32 auto. I haven't loaded any, but having the dies gave me another idea. What if you bought the cheaper 71 grain ammo and simply seated the bullets the thickness of the L-shaped plate deeper? I tried it. The magic number ended up being about .020" and the rounds loaded easily into the magazine. They fed, fired, cycled, ejected perfectly. So I had found two ways to use cheaper ammo in my Seecamp: take the magazine part out, or seat the bullets more deeply.
Does seating the bullet deeper increase the pressure of the cartridge? Sure it does. Does it increase it dangerously so? Not even close. Remember, we're only talking about seating the bullet about two one-hundredths of an inch deeper, and the .32 auto is not really a fire breathing, high-pressure cartridge to begin with. There was no discernable difference in blast, report, or recoil. A very careful examination of the primers of the spent casings showed no hint of the flattening or cratering indicative of excessive pressure. The only thing that seemed to suffer a little bit was accuracy, but my perception of that is purely subjective since I did not include that variable as part of my experimentation.
