These are my results using a Kimber Camp Guard with the original 5" barrel
All loads are with new Starline brass and CCi primers.

9.5 Longshot, Nosler                        180  JHP        1344 fps
11.0 Blue Dot, Nosler                       180 JHP         1332 fps
9.0 Longshot, Nosler                        180 JHP         1291 fps
11.5 V V N-105                               180 FMJ         1291 fps
11.0 Blue Dot  RMR                         180 FMJ         1279 fps
10.5 Blue Dot, Nosler                      180 JHP          1274 fps

And yes, the primers are a little flat and the brass ends up 20 feet away. But, not one bulged case yet.

I have a Lyman. The lid had to twisted very tight so it wouldn't leak. I emailed them to get a new gasket and they sent me a complete new tub free of charge. No more leaks.
