UK fowler Posted August 19, 2010 Report Share Posted August 19, 2010 steel 3# are big on pigeon most factory ammo marked up as a 3# is 3.5mm not 3.3mm a steel 5# is 3mm same as a 4# in lead and a steel 4# is 3.25mm so your always one size bigger in steel which can make a big drop in pellet count an oz of 3mm is just over 240 an oz of 3.25mm is down to aprox 190 thats a big gap if you trying to put 140 hits on that 30" circle? iv noticed before that basc dont pick up on this I think you may have misinterpreted the point i was trying to make steel and lead are not size for size gamebore remington express and winchester all load a steel 3# at 3.5-3.6mm a uk lead 5# is 2.8mm thats a shot size jump of three sizes not two and a lead 5# pellet count of 220 and a steel 3# pellet count of 155do not show a ballistic parity Quote Link to comment Share on other sites More sharing options...

(i counted 242) i couldnt mesure the diameter, thats why i went for shotcount per oz. Quote Link to comment Share on other sites More sharing options...
UK fowler Posted August 19, 2010 Report Share Posted August 19, 2010 stand corrected on the express only ever used game bore and thats not often,they load all there steel to the closest metric US size ie us 4#=3.3mm game bore 4#=3.25mm its about time this got standardized to make it worse express hevishot 3# is 3.2mm Quote Link to comment Share on other sites More sharing options...
UKPoacher Posted August 19, 2010 Author Report Share Posted August 19, 2010 32g #4's should be ok for pigeon. How do you think 28g of 7.5's in steel would've faired? Serious question. No idea. Never tried them. I don't think they would rattle my fillings as much though. Quote Link to comment Share on other sites More sharing options...
Floating Chamber Posted August 19, 2010 Report Share Posted August 19, 2010 3mm diameter pellets? Bit excessive for pigeon, what? Quote Link to comment Share on other sites More sharing options...
UKPoacher Posted August 20, 2010 Author Report Share Posted August 20, 2010 3mm diameter pellets? Bit excessive for pigeon, what? Yep, that's why I would have preferred to try #5's or even #6's but they aren't as readily available. Quote Link to comment Share on other sites More sharing options...
poontang Posted August 20, 2010 Report Share Posted August 20, 2010 No idea. Never tried them. I don't think they would rattle my fillings as much though. Fair comment. Just wondered, as so many on here seem to advocate there use on live quarry. My suspicion is that it's all down to saving a couple of quid. Interesting though that using the correct size steel cartridge has no financial benefit. Quote Link to comment Share on other sites More sharing options...

anser2 Posted August 20, 2010 Report Share Posted August 20, 2010 I am guessing you are reloading your own at that sort of speep Cookoff. Its high time UK cartridge makers got their act togeather and used standard shot sizes and gave detailson the box of pellet speed and pressures , veloicity so on. Most UK cartridge makers use UK sizes for lead , but US sizes for steel. After all if you buy a tin of beans it gives you all the ingredents , E numbers and all. And a tin of beans is not going to blow your head off. Quote Link to comment Share on other sites More sharing options...
