    357 Magnum

    I got some 190gr hunter supply WFN bullets yesterday. Going to see what I can do with them in my 4Ē GP100 357mag. I think Iím going to start with 2400 and H110.

    I have access to 6"Sec 6 and a 5-5/8 3 screw OM BlackHawk. I loaded some 170 HC Speer over 14.5 H110 from the rifle data section of the Lyman book . They're fantastic in the 18" 1894 C . I think that was when I broke my wrist the first time . I fired 2 in the Sec 6 thinking maybe my grip was bad the first time . My grip was fine not so much the load .

    Well I shot both loads Sunday. 25yds off a rest. The 2400 load was 1250fps and had a 3Ē 6 shot group. The H110 load was 1225fps and a 3.5Ē group. It was 91į out the H110 had a little bit of sticky extraction, but Iíve had worse out of factory ammo. Both powders showed promise, Iím going to reduce the loads a little and see if that will tighten up the groups a little.

    And, no broken wrist? Good work, seems like a good start.

    I reduced the loads a little, hoping for a bit better accuracy. No dice, both loads shot just about the same as last time. Back to the drawing board.

    Iíve settled on 11.7gr of 2400 with this 190gr WFN. After shooting it a few more times, I realized I was the culprit. Itís been consistently printing sub 3Ē groups at 25 yards. I think thatís the best this guy can do.

    I loaded some of these 190gr WFN bullets for a friendís GP100 and 12.9gr of H110 was extremely accurate out of it. He wanted a round for his 357 that could take down a Bigfoot. I told him this one was guaranteed to go through 2 Bigfoots.
