I trying to use the 180 XTP with H110 in mine. Loaded up some with 20.6 which I found on the internet for the revolver at 1350 fps. Don't use it. I fired three shots. 1st one was hard to open the action with a protruded primer, the 2nd was easier to open with the same primer problem but the 3rd actually blew the primer. Thats when I stopped. I will pull the bullets and find a safer load. Maybe MSP Ret could help us both on this round. Let me know what powder and charge you are using. I would be happy with 1.5 at 100 yds with the XTP.
WOW.. even with out your explination that load sounds WAY HOT!!! 1350 from a REVOLVER!!!!?
1100-1150fps is more like it, as you know revolvers are vented barrels, so top vel are never attained in one. With an advertised 1350 from one with really be 75-150FPS MORE in a reg barrel. Thats pushing 1500fps. There ain't a 357 mag that can come close to that number!!!
I would NEVER use there data again!!! Please BE CAREFUL of where you get your loads!!!!!Something I do when getting possible erronious <sp> data, is to cross referance with a couple other sources. Heck, you could even post up here and ask. PLENTY of us have alot of experience to get more accurate info.
My first excursion into handgun hunting came with a then new Colt Whitetailer. It was an 8" barreled 357mag. I shot a couple does with that gun and a 140 Speer HP bullt and H110 powder. I used 19 grs IIRC, that got me a bit over 1200fps. THAT was fairly hot load with flattened primers, but smooth extraction. So your 20.5gr load combinedwith an almost 30% heavier bullet...
. Like I first mentioned...WOW, I'm VERY happy your still here and have use of your hands!!!
I fooled with the 140XTP when it came out and at revolver velocities it performed well. I also really like the 158 FP XTP in the Marlin 357 Carbine. Opens up well and penetrates better than most. In the pistol its a bit too tough, save it for a case with more cap, like the Maxi.I dont like to use of 180's in the 357mag. The 170 is my max weight for it and that only in a rifle carbine. The 180 in a rifle/carbine its OK if you keep the range short, but the mag case just lacks the powder cap to carry enough powder to get the bullet moving to retain good/humaine vel/energy numbers. IMHO in a carbine/rifle your better off with that 158FP/SP HP's tend to open up too quick, unless the shot is longer but then energy is down. So a humaine kill is less probable. In a pistol that 140XTP is good medicine.
I haven't fooled with the 360 so cannot comment on its performance, but if as others have said its right on the heels of the Maxi it too should be fine.
