Hotsauce Posted March 10, 2011 Share Posted March 10, 2011 I ordered some on Monday and they were here in 2 days, that is awesome. But here is the question, I ordered 500 of 200gr swc in 18 brinell and 12 brinell. I understand the 18 are for faster velocities. But since I do not have a chrono, should I just load at the higher of the recommended scale out of the Lyman book? I don't recall the actual numbers, but if the low grain is 4.1 and the high is 5.2, should I start with the 4.1 on the 12 brinell bullets and the 5.2 on the 18?

want2race Posted March 10, 2011 Share Posted March 10, 2011 4.2 of Clays should make major if that's what you're after. Use the 18's for that load. Link to comment Share on other sites More sharing options...
JakeMartens Posted March 10, 2011 Share Posted March 10, 2011 4.2/4.3gr of Clays at 1.25 oal is a great load and makes major out of a fullsize 5inch barrel 1911 (well it does in all of mine) Link to comment Share on other sites More sharing options...
Hotsauce Posted March 11, 2011 Author Share Posted March 11, 2011 I have tight group and 700x, any loads for those? Link to comment Share on other sites More sharing options...
GSWEAR Posted March 11, 2011 Share Posted March 11, 2011 4.3 or 4.5 TG and a 200gr LSWC is a nice load but probably won't make major pf, depending on the gun 4.8 to 5.0 TG will make major. Link to comment Share on other sites More sharing options...
Hotsauce Posted March 11, 2011 Author Share Posted March 11, 2011 major pf? Remember I am new, what is pf? Link to comment Share on other sites More sharing options...
dsmw5142 Posted March 11, 2011 Share Posted March 11, 2011 (edited) major pf? Remember I am new, what is pf? PF=Power Factor and/or Power Floor Some examples-Minor PF for USPSA and IDPA Stock Service Pistol (SSP) and Enhanced Service Pistol (ESP) is 125. Major PF for USPSA and IDPA Custom Defense Pistol (CDP) is 165. These are the minimums. Power Factor/Floor is calculated by multiplying muzzle velocity (of bullet shot over a chronograph) by bullet weight and dividing by 1000. Your ammunition needs to meet the minimum PF for each division you shoot in. If it does not you could, in some cases, shoot for minor scoring (which is scored less than major) and/or disqualified from the match. For instance... a 147gr bullet traveling at 865fps would have a calculated power factor of 127 (147x865/1000=127.155) Hope this helps.
