Markio Posted December 10, 2009 Report Share Posted December 10, 2009 I thought general rule of thumb was no more than 1/2 for steel. Quote Link to comment Share on other sites More sharing options...
utectok Posted December 10, 2009 Report Share Posted December 10, 2009 No more than half for steel I agree Quote Link to comment Share on other sites More sharing options...
chris t Posted December 10, 2009 Report Share Posted December 10, 2009 I was under the impression that 1/2 choke was the equivlent of full for steel. so work it back from there. Depending on distance I personally would go for 1/4 or cylinder (both these for a double barrelled gun) Chris Quote Link to comment Share on other sites More sharing options...

starlight32 Posted December 11, 2009 Report Share Posted December 11, 2009 (edited) I/4 choke max, you are still shooting a laser beam out to 35-40 yards. Maybe worth patterning a few, to see how your gun is with them. Edited December 11, 2009 by starlight32 Quote Link to comment Share on other sites More sharing options...
willy1 Posted December 11, 2009 Report Share Posted December 11, 2009 1/2 choke max, steel patterns tighter than lead.I've just had my 20b opened up to 1/2 on the top barrel so I can use steel. Quote Link to comment Share on other sites More sharing options...

Just out of interest, does it cost a lot to have a gun "opened up" Hcc Quote Link to comment Share on other sites More sharing options...
willy1 Posted December 11, 2009 Report Share Posted December 11, 2009 Just out of interest, does it cost a lot to have a gun "opened up" Hcc I paid £30 to have mine done at John Forsey Guns in Welling,( I only had the top barrel opened)but,it can cost up to £40 per barrel.

DaveB916 Posted December 11, 2009 Report Share Posted December 11, 2009 Does the barrel need re-proofing afterwards ? Dave B Quote Link to comment Share on other sites More sharing options...

Alan Thanks for that, I was thinking of having an old sxs done 1/2 and 1/2 choke so I could use steel in, but I have just thought its not proofed for steel. Back to the drawing board.

willy1 Posted December 12, 2009 Report Share Posted December 12, 2009 My 20b isn't proofed for steel,but, when I asked the gunsmith about it he said that i could use steel providing I didn't go "mad" and use really heavy shot, and when asked about increased wear in the bores,he said that the steel stays in the wad until it leaves the barrel.If this is wrong,then i apologise,it's information from a gunsmith ,not my opinion.

Alan Check the proof marks on your gun and make sure you don't exceed the service pressure (should be marked in tons per square inch/kg per square cm). Steel shells should tell you on the box what guns they're suitable for. You should get away with some of the lighter loads but probably best to stay away from anything too heavy, and as already mentioned nothing tighter than 1/2 choke.

willy1 Posted December 13, 2009 Report Share Posted December 13, 2009 (edited) I was advised by Phil at John Forsey Guns to stick with 24gm no 4's for my gun,which,by the way ,is an Investarm 20b o/u,and both chokes are now 1/2.

willy1 Posted December 13, 2009 Report Share Posted December 13, 2009 I've checked on Gamebore Cartridges website and came across this in their Q&A Q "What choke should I use and do I need a special gun?" A "You can safely use Steel 32gram loads in all 2 3/4" chambered guns using shot sizes 5&4.If you choose to use a larger 3, 2, or 1,then you need to use a higher performance Steel shot proofed gun with barrels and choke designed for Steel loads.Steel cartridges have tighter patterns as the shot remains round with no deformation. 1/4 and 1/2 choke is ideal. I hope that helps to explain. Alan Quote Link to comment Share on other sites More sharing options...
