SP101 ammo question.

Wanna make a bet on the ability of Ruger to handle hot 125 gr. loads? I have one right here that has the forcing cone turned into carburized and brittle steel from feeding it those loads. But don't take my word for it, get a copy of Kuhnhausen's Ruger DA revolver shop manual. He has lots of photos of Ruger revolvers that customers brought to him that look just like mine and warns people not to do this. Very hot light bullet loads wreak havoc on the forcing cone just like a gas cutting torch will. Topstrap cutting will stop after a while but the forcing cone just keeps getting blasted. I am not saying you will blow the gun up but you will be looking at a new barrel if you feed ANY revolver a steady diet of 110-125 grain .357 loads. It only took me about 3 months to see what happens. I sure wish someone would have warned me about this. But I was in love with all the flash and blast. You can shoot them once in a while but you really need to limit use of this stuff if you want your barrel to last. This is not internet theory or rumors. It is well documented. Ask any gunsmith who has worked on revolvers for a few years. It is not a weakness of Ruger, it is the laws of physics. The problem IMO are those hot light bullet loads. There are definite limits to what a gun barrel can withstand.

I think I loaded about 18 gr of win 296 behind a 158 gr jacketed hp, one grain over max. in my gp. It felt very intense, but it grouped well at close range.
I'd be very careful about those overpressure loads.
While they are strong, they are not indestructible.

I have a 3" with a CTC grip. With 125grain SGD bullets and a max load of H110 it's down right painful. Mostly because of the laser hitting my finger, but even without the laser I'd expect it to be very uncomfortable.

I also shot some H110 max loads with 158 and 180 grain XTP's. They handled very well.

I've actually got some data let me check.

125SGD 21.6grain H110 1367fps/518ft/lbs
158LSWC 8.0grain Power Pistol 1108fps/430ft/lbs
158XTP 16.6grain H110 1096/421ft/lbs
125SGD 10.5 HS6 1181fps/387ft/lbs
180XTP 13.4 H110 953/362ft/lbs

Hope this helps
 
WHOA! I'd hate to be the one holding onto that one when it went off! Thanks for the pics. I guess I'll just load up to max and just use those for when I go hog hunting and do a mid load for targets and such.
