many moons ago I was shooting my 41 GNR in a S&W M-57 and I also had my 44 in a S&W M-29. The 41 GNR is based on a 44 mag case so it was easy to get them mixed up. Thinking I was being very smart I bought 500 nickel plated 44 mag brass and loaded all of them up with my Smith's favorite load, 28 grains of 296 with the Sierra 170 grain bullet. I took the gun out to do a little groundhog shooting and fired a couple of rounds and the brass wouldn't come out. I had to take it home and pound it out with a rubber mallet. It took a while talking to myself before I realized the problem. I checked the case capacity and came up different than before. The nickel brass was coated nickel inside too so the case capacity was lessened by at least half a grain. I ended up loading 27 grains of 296 and all worked well, after I pulled 497 rounds. That was a hard lesson to learn.
So to keep from getting in the same sticky wicket, drop your load by at least half a grain and 1 grain would be even better.
