The Duke Posted April 21, 2011 Report Share Posted April 21, 2011 Can anyone help with some load data, I’ve picked up some more components for reasonable money, however do not have the data, Any info would be appreciated, or a pointer to a manual which contains it, don’t want to go buying manuals only to find it doesn’t have the loads I’m after. The components and powder I have are:- Alliant Steel BPI Multi Metal 12 Ga 3” Cheddite 76mm cases Zinc Plated Steel Shot #1 Have primers:- CX2000 CX50 Quote Link to comment Share on other sites More sharing options...
roughshooter Posted April 21, 2011 Report Share Posted April 21, 2011 I would have a look at the BPI site. I have lots of recipes in the advantages 5th edition (BPi) but they seem to ve wanting gas seals and buffer. Regards Graham Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted April 21, 2011 Report Share Posted April 21, 2011 (edited) duke, where in suffolk are you? i reload steel stuff. my data set is really limited with those components. i`ll have a look online Edited April 21, 2011 by cookoff013 Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted April 21, 2011 Report Share Posted April 21, 2011 (edited) i`ll look out for some recipes. Edited April 22, 2011 by cookoff013 Quote Link to comment Share on other sites More sharing options...
Jaguar Warrior Posted April 22, 2011 Report Share Posted April 22, 2011 (edited) I have two recipes using Alliant Steel. I figured its easy to change a wad than pwder. Both are USA experimental loads, with a velocity over the CIP (arguably low) limits. The first, for guns with 75mm chambers Maximum shot size 4.0mm. (Unless fired through barrel less than ½ choke) Guns proofed for STEEL SHOT to 1050 bars 15.0Ns Maximum velocity allowed under CIP Regulations is 430 m/s @ 2.5m [1410 fps] CIP Max. 15.0 76mm PT CX2000 36.0/2.33 Alliant Steel Vagner VP70+20ga 3mm Cork in wad base. 32g 3.5mm Overshot 3mm Cork + 76mm PT CX2000 36.0/2.33 Alliant Steel Vagner VP70+20ga 3mm Cork in wad base. 32g 3.5mm Overshot 3mm Cork + 6pt crimp 1520 fps at 3 feet (USA) 1458 at 2.5m (Europe) 758.63 Pressure Bar at 1" 14.82 Momentum (NewtonSeconds) 12 gauge with 89mm Chambers Maximum shot size 4.0mm. (Unless fired through barrel less than ½ choke) Guns proofed for STEEL SHOT to 1050 bars 15.0 Ns Maximum velocity allowed under CIP Regulations is 430 m/s @ 2.5m [1410 fps] CIP Max 15.0 86mm PT CX2000 45.0/2.92 Alliant Steel CGR350 + Mylar Wrap for shot sizes above 3.3mm 42g 4.5mm shot Frangible Disc + RTO 1450 fps at 3 feet (USA) 1390 at 2.5m (Europe) 724.14 Pressure Bar at 1" 18.56 14.82 Momentum (NewtonSeconds) These formulas are for Educational purposes ONLY and have NOT been tested to CIP Regulation standards. All loads fall outside of the maximum CIP Velocity restrictions. Again, you would need to verify this. The cutting and pasting was a *****, I've checked the figures but its all at your risk. Hope this helps. JW ______________________________________ Edited April 22, 2011 by Jaguar Warrior Quote Link to comment Share on other sites More sharing options...

Hope this helps. JW jw. the recipe is a published one. it has been tested (as you have all the data there) the loads, if tested by a laboratory, will state that it fails the cip restrictions, but the shells are safe to shoot. they just cant be sold. kind of like a gun that doesnt have proof marks. (needs proofing or re-proofing before sale.) you are correct in saying all this. and this is an example of a great data set. the cip is a governing body that restricts the "performance" of shotshells. any shells that exceed this. can not be sold in the UK. although i`ve been hearing that the restrictions could be relaxed. the cip states, that steel shells must be labelled "steel shot" steel shells must have a v1 of less than or equil to 1400fps steel shells must recoil less than 15ns. (i think) steel shot must be smaller than a certain size (4mm). these limits are posed to reduce pressures (powder manufacturers have responded well to this.) reduced recoil, because old wood game guns, stocks break when high recoiling ammo is used. speed is reduced because steel shells can blow open older style chokes (older guns) Quote Link to comment Share on other sites More sharing options...
