fieldwanderer Posted August 16, 2012 Report Share Posted August 16, 2012 I want to make a very fast cartridge, and curiosity has prompted me to ask this..... 209 primer 21.5gn vectan AS guilandi (sp?) 28g wad shot, obviously. I believe this is a fairly fast cartridge already but would be willing to sacrifice some of the shot weight for a higher velocity or use different primers or whatever. can it be done by, for example, increasing to 22gn AS and dropping to 27g of shot?

Guest cookoff013 Posted August 16, 2012 Report Share Posted August 16, 2012 er..... what you dont realise is that what you propose to do, would not produce anything majorly different. if you are adament to shoot very fast loads, you can shoot 21gram lead loads at 1600 and 1700fps and still be under cip pressures. your reloader probly already drops 27.5 grams of shot for a 28gram load anyway. without insulting you, too much, get some new data. if i recolect, 24grains of AS under 24grams of shot is quick, i`m also lead to believe it can be pushed alttle quicker. but please find the data first. 21gram loads can be whipped out of shotguns really quick. about 25 grains of titewad, i`ll dig up the data. i`ve been meaning to try them for ages Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted August 16, 2012 Report Share Posted August 16, 2012 *cough* from BPI Load# 90625-985 HULL: CHEDDITE 12-gauge 2.75” PRIMER: CH209 PROPELLANT: HODGDON TITEWAD 25.0 gr. WAD: PT1205 SHOT: 3/4 oz. (328 gr.) Lead shot CRIMP: FOLD Result: PSI 9800 FPS 1600 do not even think vectan AS is even in the same burn rate as titewad. titewad is "way" faster and pretty much knock the socks of AS. but thats my personal oppinion.

fieldwanderer Posted August 16, 2012 Author Report Share Posted August 16, 2012 I have data cookoff, it's more of a general question though - your comment about it not making any real difference more or less answers it, thankyou. I ask questions to learn, it's easy enough following data and I can work various things out from several similar "recipies" but I like to understand things too, background knowledge if you like. For example, you may well have known that a cx2000 primer just seems to work better with AS and could well give an extra couple of hundred fps for negligible pressure increase - and that, to me, is all useful info (I don't know that by the way, it's merely an example and shouldn't be followed).

Guest cookoff013 Posted August 16, 2012 Report Share Posted August 16, 2012 (edited) Lead Shot 12 bore 1 1/8 oz. 32gram Longshot 36.6 grain Ched. 209 Fio. TL1 9,800 PSI 1530fps cheddite 12bore, that is a cartridge to loosen the fillings. Edited August 16, 2012 by cookoff013 Quote Link to comment Share on other sites More sharing options...
fieldwanderer Posted August 16, 2012 Author Report Share Posted August 16, 2012 Yeah, sounds it! I think what I've got at the moment 21.5gn AS 28g shot 209 primer Relevant wad Is coming out at 1350 fps and 9500psi (I'm at work so speed and pressure are from memory). I haven't got any data for what I'd like to do next, I don't want to buy any other components though as I've spent a fair bit on reloading stuff this month; It's specifically for clays, using gamebore 70mm pink hulls. 7.5shot and the reclaimed 209 primers I have and AS. I'd like it as fast as possible and am prepared to loose a little weight in shot (down to about 26g). Any suggestions? Or stick with the same (28g & 21.5gn)?

sitsinhedges Posted August 16, 2012 Report Share Posted August 16, 2012 What exactly do you think you stand to gain by making shot go faster apart from increasing the recoil? Quote Link to comment Share on other sites More sharing options...
fieldwanderer Posted August 16, 2012 Author Report Share Posted August 16, 2012 I'm just trying things out s.i.h. Carefully of course but its all part of the fun isn't it? Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted August 17, 2012 Report Share Posted August 17, 2012 irony is, the quicker softer lead shot is fired at, the more the pattern is blown. Quote Link to comment Share on other sites More sharing options...
fieldwanderer Posted August 17, 2012 Author Report Share Posted August 17, 2012 Soo, you see, by asking that one question I now know; About all I'd gain is recoil If I really insist on going faster, I need a different powder (I.e. I can't really get much more out of AS) If I did go faster, the pattern would deteriorate which..... With the reduced load I suggested, would be a **** idea. Cheers fellas, I'll stay with cheap and cheerful - they work fine. Quote Link to comment Share on other sites More sharing options...
