I loaded up some .357 Mags last night to see about some close in hog loads. 13.5gr of H110 behing some Oregon Trail Laser Cast 180gr Flat Points. Winchester Small Pistol primers. These are for a 686+ with 4" barrel. Manuals all state around 1300fps, but I was clocking 1010. I know the shorter barrel will lose some velocity, but that much?
There were no signs of excessive pressure, in fact the primers were not flattened at all. Normally I would start increasing the powder charge at this point, but none of the manuals show any load higher than 13.5gr with this bullet weight so I am somewhat hesitant to do so. Is this powder just too slow for this barrel length? Should I abandon the thought of increasing the charge?
Does anyone have experience with a similar gun/load combination?
