Jim Miller Posted March 26 Share Posted March 26 When looking at load data for the 38spl round it would seem that the WB 150 PF is easily achieved. I tested my Cowboy knock down loads with 158grn bullets. With an average of 969fps they gave a PF of 153. Well within the SASS max of 1400fps. As this was with low humidity and at 6,000ft I may have to up the charge a little to be comfortable wherever I travel. All rounds tested were started with a clock held one step directly behind and at waist height both under cover and in the open. All rounds were recorded.

marshal stone Posted March 26 Share Posted March 26 I did some testing with factory .38 HSM and Winchester cowboy action loads. (158 gr. bullet) I did the test with the rifle flat and tipping it up to about 170 degrees between shots. Rifle used was a Uberti 357 with a 20-inch barrel. Testing was done in an indoor range use a Lab Radar chrono. Temp was about 65. We are about 400 ft. above sea level. HSM flat gave a power factor of 157.1 Tipping up gave a power factor of 158.8. Winchester flat gave a power factor of 167.6. Tipping up gave a power factor of 169.8. So, as you can see 150 PF is easily attainable. Just need the minimum bullet weight for 38/357 to be 158. WB ROC and TG's need to consider this. Marshal Stone 1 Quote Link to comment Share on other sites More sharing options...
July Smith Posted March 26 Share Posted March 26 Is there a PF requirement for the rifle now? I agree it is easy to make 150 PF with a fairly moderate 38sp load, but I though eliminating the PF for the rifle was one of the more controversial rule changes.

Jorge Posted March 26 Share Posted March 26 The minimum power factor for rifles in SASS Wild Bunch is 60. The minimum power factor for .45 acp is 150. 1 1 Quote Link to comment Share on other sites More sharing options...
