38 SPL +P OUTDOORSMAN - 158 gr. Hard Cast Keith 1,250 fps - 20 Round Box


This load was designed for those who need a deep penetrating 357 mag. or 38 SPL load to be fired from lightweight alloy 357’s and any 38 SPL revolver. Lightweight alloy 357’s develop multiple problems when firing our 180gr. 357 mag. hard cast turbo charged (Item 19A) ammo or any make of full power 357 ammo. Yet many folks want a deep penetrating “outdoor” type of load for their lightweight pocket 357’s, so here it is. Whether you are shooting gators or bears in the head, this load utilizes a hard flat nosed bullet, at sufficient velocity, even from 2 inch barrels, to fully penetrate either.

This load is safe to shoot in all 38SPL and 357 magnum firearms of modern design that are in normal operating condition. In the super lightweight alloy revolvers (around 11-12 oz.) the bullet will not jump crimp under recoil provided you do not subject an unfired round to more than 5 or 6 firings. In all steel guns, even short barreled ones, crimp jump is not an issue as the all steel snub nosed revolvers are much heavier than the alloy versions.

This load utilizes a flash retardant powder that will not blind the shooter in low light conditions, which is important as wildlife and criminals get much more active when darkness comes.

This bullet is hard cast and properly lubed and as such will not substantially lead your barrel. You should find no degradation of accuracy when firing many cylinders full of this ammo without cleaning.

We never use extra long laboratory barrels to produce our advertised velocities, which we feel is dishonest to the customer as those extra long barrels produce extra high velocities, which you cannot duplicate with stock revolvers in the real world. Instead, we use stock firearms and you can see the velocity results below.

Brought this to the range for my LCR 357. It's not 357, but it's not far from it. Definitely the most potent 38 P I've run across yet. I never considered the LCR to be a hiking gun, but now I might change my mind.

I bought this for my GP100 357 and it does not disappoint...I tried it on the range and will carry it with me on my next New Hampshire Hunting trip where black bear are plentiful in the white mountain area. Very good hard hitting load without too much recoil, more hard hitting then any other average 38 special load but just under the kick of 357 ammo, almost borderline... I have a 4.2 inch GP
