longgun Posted March 5, 2014 Report Share Posted March 5, 2014 Hi, I want to reload 32g cartridges with Vectan A1 at 1200 fps. Either fibre or plastic wad but if it's possible, would like to try both. I found a couple circa 1100 and 1300 fps data here in forum but couldn't find any at 1200 fps. Do you know or have any?

Guest cookoff013 Posted March 5, 2014 Report Share Posted March 5, 2014 eh? vectan AS can do that, cleaner too. if you have data for 1100fps and 1300fps just go for inbetween? in all honestly the speeds quoted on boxes of shells, are from a proof gun, and extrapolated for MV. (ie guessed (chuck on 50-100fps) Quote Link to comment Share on other sites More sharing options...

(ie guessed (chuck on 50-100fps) +1 The velocity will vary with ambient temperature on the day. Variation between shells will change velocity, eg accuracy of powder charge, how hard you compress the wad, tightness of crimp etc. If you drop the powder charge by 5% on the 1300fps load you're probably as close as you're going to get.

longgun Posted March 5, 2014 Author Report Share Posted March 5, 2014 Well, I found at 1100 and 1300 fps but with different powders. The 1100 fps data with AS and the other with A1. And yes, conditions affects the results but if a gent suggests any, my next question will be to ask the conditions. Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted March 5, 2014 Report Share Posted March 5, 2014 wouldnt be to bothered with conditions, just select a decent recipe, usually if the pressure is great (ie within 8000-10500psi) its usually clean, burns well, great consistency in seed and pressure.
