psl sniper 963 Posted April 2, 2012 Report Share Posted April 2, 2012 so i worked up another slug load, using ramshot zip powder. zip has a slower burn rate than the wst powder i was using previously. unfortunately there is zero info using zip powder for shot shells. so i started low and worked up. started with 18 grains and increased the the load by 1 grain until i reached 28 grains. at 28 grains it was showing no signs of overpressure, but i decided not to push my luck. i backed it off to 26.5 grains and am quite happy with them. hull Winchester universal. win 209 primer 26.5 grains of ramshot zip. wad aa 12 projectile. lee key hole slug (1 0z) if you decide to use a smaller powder charge you will need some type of cardboard spacer to get a proper crimp. as it is they crimp quite nicely. i have no idea what the velocity is (definitely faster than my first load), they cycle my s12 on setting 1 with 0 cycling issues. use all info at your own risk! 1 Quote Link to post Share on other sites
patriot 7,197 Posted April 2, 2012 Report Share Posted April 2, 2012 What's the pressure? Either PSI or LUP will be fine. Quote Link to post Share on other sites
IndyArms 10,186 Posted April 2, 2012 Report Share Posted April 2, 2012 What's the pressure? Either PSI or LUP will be fine. WIthout any LOAD DATA... and the proper scientific apparattus to measure pressures of a fired cartridge... I dont think you will get ANY info along THAT route...

Rhodes1968 1,638 Posted April 2, 2012 Report Share Posted April 2, 2012 (edited) BTW Indy your suggestion of using silicon chalking instead of wax works well in a double barrel. Wont melt and is a lot firmer than wax. Results are every bit as impressive as any slug. Edited April 2, 2012 by Rhodes1968 Quote Link to post Share on other sites
psl sniper 963 Posted April 2, 2012 Author Report Share Posted April 2, 2012 (edited) What's the pressure? Either PSI or LUP will be fine. WIthout any LOAD DATA... and the proper scientific apparattus to measure pressures of a fired cartridge... I dont think you will get ANY info along THAT route... exactly! i suppose i could send a few out for testing. a couple things to watch for when working up a load. 1 check the primers. if it looks like its bulging around the firing pin strike, or looks like its being "pushed" out you may be reaching the limits of your pressure. 2. check the base of the hulls. 3. check the hulls for bulges or splits. granted its probably not the most ideal powder, i had a half pound left over from when i used to load 9mm. and i wanted to get some use out of it. so i decided to do some research on the burn rate and work up a load starting light. when im testing a new load i generally use an old bolt action shotgun. like indy said, without actual data or testing equipment you wont know the exact pressure. however i feel the pressure is completely within safe limits as i have had zero issues with the primers or extraction of the shells. again all data is for informational uses only. if you choose to copy said data you do so at your own risk.

dolomite_supafly 56 Posted April 2, 2012 Report Share Posted April 2, 2012 I cut the tops off of Federal bulk. Melt the shot into a .690" round ball then drop it back into the case. Works great and costs me .23 a round. Dolomite Quote Link to post Share on other sites

RED333 1,025 Posted April 2, 2012 Report Share Posted April 2, 2012 That sounds like a LOT of powder, what perssure is the base load? Quote Link to post Share on other sites

Too much work for me considering I will never pick up the hulls. I made a die that doesn't crimp but tapers the nose of the hull. I think it helps make it more reliable with the pointed front as well. I have fired at least 200 rounds this way without a single issue. Dolomite Quote Link to post Share on other sites

RED333 1,025 Posted April 2, 2012 Report Share Posted April 2, 2012 I use Alliant Green dot, 18.5 grans makes 10,100 PSI. I just thought you might know what the base pressure was.

RED333 1,025 Posted April 2, 2012 Report Share Posted April 2, 2012 Making up loads always made me a bit nervous, just be careful, and it looks like you are. I have not had a firearm go boom in the wrong place yet, and dont want to push it. I tend to stick with what is known and dont stray far form that. Quote Link to post Share on other sites
psl sniper 963 Posted April 2, 2012 Author Report Share Posted April 2, 2012 hey red im having trouble finding the data you described. what weight of slug are you using? hulls? wads? according to their data 18.5 grains with a 1 oz shot load should only run 7100 psi. and thats with shot. slugs will run lower pressure as they dont expand down the barrel like shot does. 1 Quote Link to post Share on other sites
RED333 1,025 Posted April 2, 2012 Report Share Posted April 2, 2012 I use the load data for 1 1/8 oz shot. (as that is what was in the hull) 18.5 grans powder. 1 oz Lee slug. CCI 209M primer Win bulk hulls I did not know the pressure would be lower for a slug. I am going to go with you on that one. My S12 eats the load well, good recoil and no FTE.

WAD? if you are using 18.5 grains of powder with a 1 0z slug then your pressure is going to be WAY lower than 10,100 psi you quoted earlier. it should actually be closer to 7,600 if you go by aliants data and you should be getting around 1,145 fps velocity. personally if i where going with green dot id go with this recipe http://www.alliantpowder.com/reloaders/RecipePrint.aspx?shotype=&weight=1&weightdis=1&shellid=493>ypeid=3&gauge=12&lid=681 1300 fps with 8700 psi. not too shabby. 1 Quote Link to post Share on other sites
IndyArms 10,186 Posted April 3, 2012 Report Share Posted April 3, 2012 I wuldnt consider 26 grains of powder to be a LOT of powder... Start shooting some of my 1 1/8th oz hunting loads with 36 grains or so of LONGSHOT powder... talk about KICK!!! WHOOO HOOOOOO!!!! wanna talk about FAST... almost 1600 FPS!!!!

psl sniper 963 Posted April 6, 2012 Author Report Share Posted April 6, 2012 ok so ive done some more research and found a burn rate chart on hodgdons web page. http://www.hodgdon.com/burn-rate.html it puts ramshot zip right next to IMR, Co SR 7625 but just a little slower so cross referencing the load data sheet i came up wit this. http://data.hodgdon.com/shotshell_load.asp according to that the pressure using 26.grains of zip with all components described should be right around 6600 psi with a velocity of 1250. granted this is not an exact comparisson. 1 Quote Link to post Share on other sites
msrdiver 42 Posted April 9, 2012 Report Share Posted April 9, 2012 For testing velocity and pressure I recommend Tom Armbrust. I've trusted him for dozens of loads. His equipment includes: Chronograph: Oehler M-35P Skyscreen III Ballistics barrel: Krieger that is 30" long, about 2" in diameter, with a skeet bore. He was charging $5 per shell and I send him 3-5 shells per test load. Tom Armbrust 1108 W. May Avenue McHenry, IL. 60051 All loads must be sent to him via ground. I've had good experience with UPS ground. Do NOT use the US Postal service. Quote Link to post Share on other sites
