Few months ago, picked up a WWG converted XD45 5" Tactical 460 Rowland. First trip to range with it found some reliability issues, a few minutes back in the WWG shop for some spring adjustments, and all is well.
I loaded up 3 different combinations, in addition to the Cor-Bon factory ammo for comparison:
very controllable, about 5" groups at 15 yards off hand (not thoroughly impressed with accuracy, but is good enough for my purposes--- the XD doesn't have the smoothest trigger in the world either)
200gr FMJ truncated cone:
13.8 gr Longshot
1465 avg fps
Hard on hands, mild pressure signs, loaded to max saami length, and truncated cone design hung up in mag with more than 5 rounds in it.
250 gr Hunter's Supply hard cast lead Flat Nose
1160 avg fps
Good function, occasional flattened primer, easy to shoot
260 gr Speer Uni-Cor JHP
9.0 gr Longshot
1055 avg fps
Good function, felt like mildest load, no pressure signs
A few other notes, I've been cautioned by Johnny Rowland and others that once a round has been chambered, it needs to be shot- repeated chambering of the same round can push the bullet deeper in the case, causing higher pressure. While dropping a loaded cartridge into the chamber, vs an empty brass, I noticed that the bullet touched the lands before the rim reached the end of the chamber. I think that this is because the 460 Rowland chamber is made by deepening the 45 ACP chamber by 1/16 of an inch, therefore removing any throat that was once there. I don't really know for sure, but this makes sense to me.
Also, any thoughts on what combo of what I've loaded that you would use as a wilderness protection load? I don't think the 200gr TC would be built strong enough or penetrate deep enough. The 250 gr flat nose feels really good to shoot, and should be hard enough (16 BHN) to hold together. The 260 gr JHP is a hollowpoint, which I tend to shy away from for penetration purposes. What do you all think?
