seasprite Posted February 10, 2013 Report Share Posted February 10, 2013 Started a new load today since the weather was nice today (I thought of you today imschur ) and I had to get some trigger time. My goal with this is a plinking load with mixed brass. The components are Winchester primers, CFE223 powder, 147gr pull downs and mixed cases. Starting charge was 48.4gr ending was 50.8gr. Book values were starting 48.4 and max of 51.5gr. Since this is going in mixed cases I new I wasn't going for max so 50.8 as far as I loaded test rounds to. My col was around 2.820 but those of you who have loaded these pull downs know they are pretty inconsistent so if they fit in the mag they were good to go.Took the chrony with me today but the results were not what I expected <dontknow> it was cloudy today so that might be why. here's my averages with ES and SD'spowder fps es sd48.4 2599 29 1548.7 no test49.0 2582 8 449.3 2603 26 1449.6 2600 46 2349.9 2623 15 750.2 2579 7 350.5 2595 64 3550.8 no testI was figuring my velocities should have ended at about 2700 fps with this powder and 16" barrel especially since I'm getting 2650 fps with my 168's. Well If I was to ignore the chrony data and go off of my targets its still going to at 50.0gr charge. So here's the target pics. and I await your comments <thumbsup>.

survivalshop Posted February 11, 2013 Report Share Posted February 11, 2013 If there is not much difference in grouping , go with the 49 grains , on less grain of powder & same ES & SD . Quote Link to comment Share on other sites More sharing options...
seasprite Posted February 11, 2013 Author Report Share Posted February 11, 2013 If there is not much difference in grouping , go with the 49 grains , on less grain of powder & same ES & SD .The 49gr is scattered a lot more than the 49.9gr. The charge weights right before and right after the 49.9 weight seem to have the same relative point of impact even though there more spread out, gives me the impression that this weight might be the most forgiving. I've labeled my cases for the seating depth test now just got to load them up. My range is 2.775"-2.820" five rounds each. My guess is that should hit a node before getting down to the 2.775" depth then I'll pull the rest. Quote Link to comment Share on other sites More sharing options...
seasprite Posted February 18, 2013 Author Report Share Posted February 18, 2013 Well I,m done loading up my seating depth test loads <thumbsup> Now I just need a nice day to go out and test them. I also decided to play with a new tool that I have, an Hornady comparator although on the 147gr pull downs aren't exactly match bullets I figured it help me when I work on the 178gr A-max load.

seasprite Posted March 10, 2013 Author Report Share Posted March 10, 2013 I managed to get my seating depth test done before the rains moved in it was kinda touch and go with Chronograph today started to sprinkle and I thought I was going to have to put it up but wouldn't be able to until the range officer called a cold range.It looks like 2.800" is what my gun likes with load but I'm need an opinion on what I should do <dontknow> I took measurements with an comparitor and I like what I see with the 2.210" but going with that means higher ES & SD numbers. So here's the pics and tell me what you guy's would choose? Quote Link to comment Share on other sites More sharing options...
seasprite Posted April 18, 2013 Author Report Share Posted April 18, 2013 I figure I better update this thread with what I decided on so here is the final recipe for this load workup. 147gr pull downs Remington brass and nato brass Tula LR primers CFE 223 powder C.O.L. with Horndy comp. 2.10" powder charge: Rem brass 49.9 gr Nato brass 49.2 gr Med. to heavy crimp Quote Link to comment Share on other sites More sharing options...
