I have loaded 125g Remington PSP's for my wifes bolt action .30-30, and used the same loades in a single shot rifle too. They are loaded with 37 1/2 grains of H335, Win primers, and are not crimped. They travel at 2600 fps out of a 22" barrel, 38 1/2 grains is doing 2650 fps. There was no preasure signs in my rifles, but you should work up your loads and watch for preasure. I prefer using 150g bullets for deer hunting and have found H335, and IMR 4064 work very well for them. I have notes on some loads if you want more info on velositys that I got.
