islandgun Posted August 18, 2016 Report Share Posted August 18, 2016 Just ordered some copper shot and looking for load advice (have gone back throigh the search optionbut could not find specific info) I have 12 and 20g cheddite cases and primers, Steel, bluedot, longshot, AS and PSB2 and would prefer fibre wad and use a RTO closure, could I load lead or bismuth recipes ? its for old fixed choke guns cheers IG Quote Link to comment Share on other sites More sharing options...
TONY R Posted August 18, 2016 Report Share Posted August 18, 2016 Pmed you a load that will get you started with copper. Quote Link to comment Share on other sites More sharing options...

Continental Shooter Posted August 18, 2016 Report Share Posted August 18, 2016 I know Tony got you a recipe to start but i would always stress: The recipes are not interchangeable: recipes for leads must only be used for lead, recipe for copper only for copper. The consequences of not sticking with this rule can be extremely dangerous Cheers, Quote Link to comment Share on other sites More sharing options...

The consequences of not sticking with this rule can be extremely dangerous Cheers, Your right of course but all loads start as wildcats at some point, loads for one type of shot or another where shot types have similar spacific gravity and hardness , are a good place to use to form the bassis for a load, ITX 10 is close as is bismuth i sort of went off them initialy, but after a time i went free hand on copper with nothing really scary showing up on the crusher cannon, its not like steel or lead and its as safe as anything else. But a slow start of ITX 10 data is a logical place to begin with for anyone wanting to give it a try, remembere start 10 .....15% down on powder charge and creep up on the max if it looks ok get it tested, or better still load the max and get it tested then you will have some idea where you are at. Strong enphasis on ITX 10 people, Get your numbers wrong and run any ITX 13 data and the outcome WILL BE very DIFFERENT> Remember ITX 10 ok.

islandgun Posted August 19, 2016 Author Report Share Posted August 19, 2016 Thanks for your input men Tony R and FatfreddysCat for his Cheddite recipes perhaps i will try a low pressure bismuth/itx10 load Tony cheers IG Quote Link to comment Share on other sites More sharing options...
TONY R Posted August 19, 2016 Report Share Posted August 19, 2016 (edited) Well thats up to you, i will point this out for what if anything its worth, Bismuth has a ... Reputation... An unfounded on in my opinion.. Of Breaking up pellets crumbling in chokes during the internal proces on target i really am not sure where, BUT ITS Talked about let me put it that way. This fragile nature of Bismuth has powder firms data publishers etc on the steady side of pressure and vellocity in more than a few cases, so although Bismuth is Technicaly Denser in spacific gravity thus creating lower theretical pressure due to the density, its data tend to be on the low side anyway so in most loads they adjusted things down for your theoreticaly lower density copper, ITX10 as no such reservation incorporated into data, so i tend to land some where in between these pieces of data with similat weight loads of similar speed in the same kind of hulls and wads.
