NoFail Posted November 1, 2015 Report Share Posted November 1, 2015 Hi, been a long time since I've been here. I have not been very active for the last few years. I have the sound of brass wet tumbling in my ear right now, I need to get going again. I've been thinking of purchasing some Lake City once fired & I think that that brass has thicker walls, less volume, is that correct? In that circumstance I reckon a lesser charge weight is prudent, compared to the many Winchester and Hornady commercial brass I have. Any recommendations? Thanks guys, it's been awhile since I've been here. Quote Link to comment Share on other sites More sharing options...

Sisco Posted November 2, 2015 Report Share Posted November 2, 2015 Welcome back. If nothing else, do the old standby, reduce the listed charge by 10% and work your way up looking for signs of overpressure. Glad I did when I was working with Lake City brass and Reloader 15.

survivalshop Posted November 2, 2015 Report Share Posted November 2, 2015 You could start some where near the min. loading & work it up from there . Some powders react differently to case volume & temperature . A good Chronograph is always helpful . I still weigh all my brass & put them in weight categories , even with same brands. Not really necessary for blasting ammo , but for testing best groupings , it can make a difference , you can see how a little difference in case volume can alter results .

NoFail Posted November 3, 2015 Author Report Share Posted November 3, 2015 Hello & Thanks everybody! Survivalshop yes that's what I did. I do that a lot anyway, I have a feeling because of reading a lot of your posts or comments few & plus years ago helped. Quote Link to comment Share on other sites More sharing options...

FreQRiDeR Posted December 31, 2016 Report Share Posted December 31, 2016 If you want to be scientific about it, you can measure the case capacity in grains of h20 of your standard load and the lake city brass and do the math. 41gr RL15 X grains -------------- X -------------- 56 gr. H20 win 54 gr. H2O LC Quote Link to comment Share on other sites More sharing options...

H20 win 54 gr. H2O LC They say " its all about the Math " , but too many variables , chamber dimensions , Bullet make up & seating depth , also ambient temperature. , even Barrel rifling , can effect chamber pressure curve , so real world effects can be much different then the math , though its good to have that formula. Starting close to the low end of charge weight, might be safer in the long run . Quote Link to comment Share on other sites More sharing options...

Math don't lie! ;) Quote Link to comment Share on other sites More sharing options...
