biglou13 Posted April 7, 2017 Share Posted April 7, 2017 (edited) again helping friend with issues on reloads 9mm mix brass jacketed 124 gr bullet cci primer tite group (3.8 -3.9gr) dillon dies dillon 650 helping friend trouble shoot load problems i was shooting with friend to night and had an uncomfortable amount of "puff loads" bullet left barrel very soft recoil some failure to eject or sillier fault consistient oal ( out of 20 mic'd) said casings had darker markings (scorch) than good cartridges 3 different guns 2 different shooters i have 20 rounds that i will weigh later no weights yet thinking out loud....... is it possible powder gets " damp" it is possible, eventough he has powder check, that powder weight is off..... With 3.8 title group load how sensitive is powder check? ( I'll weigh in am) I'm a 550 guy so I know i doubt bullet Diameter would make that big a difference.? Static ice charge affecting drop?

Hi-Power Jack Posted April 7, 2017 Share Posted April 7, 2017 Sounds to me like there wasn't enough powder in the cases. Do you have a good light source and do you ALWAYS check each case visually to make sure you have a decent amount of powder in the case before you seat each and every bullet? Might be short stroking and not getting full amount of powder - or you have some wear in the powder dispensing area (springs, etc). I'd throw 20 cases full of powder and manually measure each one - see what's going on .... See how much powder you have in each case Link to comment Share on other sites More sharing options...
biglou13 Posted April 7, 2017 Author Share Posted April 7, 2017 Thanks jack i asked him to throw a few and weigh. I also suggested that he throw 10 then weigh... He hasn't got back to me yet...... I'll weigh the loaded cartridges that have this morning. Link to comment Share on other sites More sharing options...

The variations of all the components will make it impossible to determine with specificity what the powder drops are. Stick with the original plan...weighing 10 drops is okay, but 20 is better. He obviously has a measure issue so he should put the effort into finding out why. The issue may not show in just 10 throws.

Hi-Power Jack Posted April 7, 2017 Share Posted April 7, 2017 I didn't mean throw and weigh the cartridge ... I meant, throw a charge and then dump the powder into your scale and weigh the powder charge .... Or, throw three charges and weigh all three powder charges, together (just the powder, not the entire cartridge). Link to comment Share on other sites More sharing options...

Hi-Power Jack Posted April 9, 2017 Share Posted April 9, 2017 (edited) If it's only 4%, you might need a larger sample than 15 to find a single PUFF. Possible your reloader needs some lube, or a spring is wearing out. Also likely that over time, the % will increase from 4% to 6 or 10%.

BeerBaron Posted April 10, 2017 Share Posted April 10, 2017 Where was the spent primer? does he have the powder check? is powder sticking to the powder check rod end? what brand of primers? Link to comment Share on other sites More sharing options...
