ATMester Posted March 15, 2007 Share Posted March 15, 2007 Hi, I just chronoed my loads again. Clays, WLPP, Win. case, 1.222 oal, crimp is .470, Precision 230 gr RNF Ten rounds average on the 650 gives me 38.3 grains <---- that's what I aim for. Kimber 5" Average: 744.5 Hi: 766 Lo: 723.3 Es: 42.7 Sd: 11.5 Ad: 9.0 That comes down to 171.2 PF Is it too high should I dropp the charge? On the flip side I'm not worried that I have to shoot minor.... Link to comment Share on other sites More sharing options...
zhunter Posted March 15, 2007 Share Posted March 15, 2007 That is a nice safe ( not gonna go minor ) load!!! Link to comment Share on other sites More sharing options...
Larry White Posted March 15, 2007 Share Posted March 15, 2007 I think I would run off about 2K of those and go test them.-------Larry Link to comment Share on other sites More sharing options...
38superman Posted March 15, 2007 Share Posted March 15, 2007 (edited) You're right where you should be. You need to have a little margin for error. Ammo that chronos 167 PF at home has a way of going 163 on the match chrono. Due to: False chrono readings because of varying light conditions and other issues. Lot to lot variations in powder, primers, bullets. Loading dies that slip out of adjustment. Temperature Etc, Etc, Etc. There are very few shooters that can feel a difference between a 166 and a 170 load in the field. Go with it.

ima45dv8 Posted March 15, 2007 Share Posted March 15, 2007 My target for load development is 170-171. As Tony said, that gives a comfortable chrono safety-margin without getting silly about it (no need for 185 just to make sure you make Major). You hit it first try (damnit! ).

Viggen Posted March 15, 2007 Share Posted March 15, 2007 That's a very nice place to be - enough "just in case" without being excessive. Nice job. Link to comment Share on other sites More sharing options...
XD Niner Posted March 16, 2007 Share Posted March 16, 2007 (edited) I too target 170 but will happily accept 169-171. I'm working up a Major .38 Super load now. The first batch was 163 while the next batch was 173. Just for the heck of it, I mixed rounds from both batches in the same mag and fired them off. I couldn't tell any difference in recoil or muzzle flip. Edited March 16, 2007 by XD Niner Link to comment Share on other sites More sharing options...
Steve Moneypenny Posted March 16, 2007 Share Posted March 16, 2007 way too high.. you want to shoot 165.1 at nationals.... hehe. we all know some people that has happened to. Seriously i load about 171 -172 in my 45. that's the happy zone for power factor in major. Link to comment Share on other sites More sharing options...
JD45 Posted March 16, 2007 Share Posted March 16, 2007 The velocity of my match load, on our club's chrono, was averaging 746fps. I went to a big match and almost went minor. So, no, I for one do not think you're too high. Link to comment Share on other sites More sharing options...
HSMITH Posted March 16, 2007 Share Posted March 16, 2007 Ater a close scrape at the chrono I won't dip below 173 on my chrono. I will also shoot well over 173 if it doesn't hurt. I shot a 181 PF load for a while with a Limited gun that didn't hurt me one tiny bit at the end of the day, and my current favoriite Open load is 175ish and probably will end up around 180 PF for the best performance I can expect in my gun. If it takes 185 I will go there. The timer and points are my guide once I meet the number, not someone elses interpretation of what is good for me. Call me hard headed, that isn't a problem. I will do everything in my power to not go minor and to find the best load for me in my gun. Link to comment Share on other sites More sharing options...
Merlin Orr Posted March 16, 2007 Share Posted March 16, 2007 I think I would run off about 2K of those and go test them.-------Larry Funny - but the point is there......At 171 you are perfect. Do go test them at the match chrono without worry! Link to comment Share on other sites More sharing options...
G+16 Posted March 16, 2007 Share Posted March 16, 2007 go with it, good solid PF and will give ya some if they chrono in weather that is hotter or colder than when you tested them Link to comment Share on other sites More sharing options...
LPatterson Posted March 16, 2007 Share Posted March 16, 2007 I would not change a thing. I went to an Area match in Bend with a 200gr load that had a low velocity of 850 at home and chroned before the match at 162 PF. Trying to find 300 rounds in one place in Bend was not fun and the Blazers I found chroned at 192. Link to comment Share on other sites More sharing options...
JFD Posted March 16, 2007 Share Posted March 16, 2007 170 - 172 is my target after chronoing at 165.0 with what should have been a 168 PF load at the 2005 SC Sectional. I made major, but that was a nail biter for sure until the last round was fired. It's good not to have to worry about equipment or ammo by being as prepared as possible.
