kent Posted March 4, 2014 Report Share Posted March 4, 2014 (edited) Following my request for a small quantity of large size lead to test in my double ten "casts-by-fly" donated a small quantity of Number 4 Buck, thanks Rick owe you one! Anyhow today I put the first round together. Data was based on info published in Ballistic products handbook "the mighty ten". Had to substitute Remington cases for fedral though I did have the listed FED 209A primer, steel powder and BPD10 wads. The data was 33 grns for 2 1/2 oz however you cant fit that in using the large buck but I could get 2 1/4 oz in nicely so on the basis of less shot lower pressure I gave it a go with the same charge of powder and mica dusted the wad. Only 47 pellets through 1/2 coke is never going to give very dense patterns at 50 yards, though I thought what the heck give it a go anyhow. Result 50% in a 2ft target and quite even, in reality not enough pellets to get a good reliable kill on anything like the size of a fox at that range. Suppose I might just try some pattern tightening, could be quite tidy if I can get things tighter at range (though I suppose the practical load is going to be down to smaller shot with subsequent higher strike rate like std BB / BBB). Anyone got some spare lead in smaller size to test? Fully intend to try the same load at shorter range though not entirely sure what I might use it for. Oh yes and it kicks a bit! (oh if your crazy enough to try this Data its at your own risk) Edited March 4, 2014 by kent Quote Link to comment Share on other sites More sharing options...
FatFreddysCat Posted March 4, 2014 Report Share Posted March 4, 2014 I've got 7.5Kg of lead 3 and 2kg of 1. I have no use for this since the lead ban. It's yours for free but too heavy to post. Are you in Kent? I'm often in the Tonbridge area and will be driving out to Grain on Sunday. Quote Link to comment Share on other sites More sharing options...
pestcontrol1 Posted March 4, 2014 Report Share Posted March 4, 2014 AA or they might be AAA cant remember and i have some BB not many of each but your welcome to them if there any good to you Quote Link to comment Share on other sites More sharing options...
kent Posted March 4, 2014 Author Report Share Posted March 4, 2014 AA or they might be AAA cant remember and i have some BB not many of each but your welcome to them if there any good to you Sure thing thanks, happy to pay for cheapest carriage don't need a stack of the stuff.

Thanks, I suspected a few might have some unwanted lead from the days. interested in say that KG of no.1 will happily pay carriage at cheapest rate.

kent Posted March 7, 2014 Author Report Share Posted March 7, 2014 Thanks to both the guys above i have some more sizes of lead to play with, will keep all updated. Quote Link to comment Share on other sites More sharing options...
kent Posted March 7, 2014 Author Report Share Posted March 7, 2014 Ok just put a few more together, this time with AAA (br) or 5mm for ease and also BB (br) 4mm. Able to get more shot in now 2.4 oz to be fair. Four shells of each size Quote Link to comment Share on other sites More sharing options...
kent Posted March 10, 2014 Author Report Share Posted March 10, 2014 Got to do a bit of testing today. All at 50 yards on my home rimfire range, weather was good with moderate to light wind. 4mm produced 58,53,68,44 strikes in 30" average 55.5 BOTH SHOT THROUGH 1/2 choke only 5mm produced 45,26,38,33 strikes in 30" average 36.5 Far greater energy / penetration was recorded for the larger 5mm shot penetration a new 12mm Hardy backer board mostly every pellet. 4mm however could only make its depth into the board at most. On balance I figure less pellets in the 4mm (reducing from the 2.4 oz) and more powder could be the more effective of the two on fox (UK WIDE) and geese (NORTH OF THE BORDER WERE LEGAL)To up the velocity is required. The 5mm I figure needs more choke than I can give it or buffering/ less wad slits etc.? as there was big gaps - No doubt three or four good body hits should rove fatal though I should like to see more strikes or drastically reduce the range as indicated by the count there is no guarantee on were those few shot land. Oh and nice clean barrel using the Alliant steel powder, though its not exactly pleasant to shoot as a steady aimed shot with just shy of 2 1/2 oz of shot coming out. Next step lighter and faster 4mm lead Quote Link to comment Share on other sites More sharing options...
pestcontrol1 Posted March 10, 2014 Report Share Posted March 10, 2014 2-1/4oz or straight 2oz with more speed should work better what wad was you using with the 5mm ? Quote Link to comment Share on other sites More sharing options...
kent Posted March 10, 2014 Author Report Share Posted March 10, 2014 2-1/4oz or straight 2oz with more speed should work better what wad was you using with the 5mm ? That's my thoughts on the 4mm increase speed drop shot count some (it didn't look to bad in spread over all). BPD10 wad with both, don't think I can loose the shot count with the 5mm so thinking of buffer or tightening through wad fiddling. The 5mm sure landed with significant energy levels so I find myself wondering on the possibility of reducing velocity and perhaps improving the pattern on that one?

Underdog Posted March 10, 2014 Report Share Posted March 10, 2014 Interesting.....I would keep the pellet count up.....but that's just me! U. Quote Link to comment Share on other sites More sharing options...
Old farrier Posted March 10, 2014 Report Share Posted March 10, 2014 Hi Hope you don't mind a question sorry if its been asked in past Is there anyway of measuring the pressure generated by a hand loaded shot shell or is it a mathematical equation Also could you tell me a suitable chronograph to measure speed of shot Many thanks All the best Of Quote Link to comment Share on other sites More sharing options...
pestcontrol1 Posted March 11, 2014 Report Share Posted March 11, 2014 not sure if the bpd10 wad is preslit or not if not you could just slit twice that tightens the pattern up some what i did the same whith a 3-1/2" steel load Quote Link to comment Share on other sites More sharing options...
kent Posted March 11, 2014 Author Report Share Posted March 11, 2014 Interesting.....I would keep the pellet count up.....but that's just me! U. Yeah bit of an issue though with pressure if I increase the powder to get higher energy / speed. reducing the shot charge allows for more speed and more powder, the 4mm are too light hitting at present Quote Link to comment Share on other sites More sharing options...

I suspect buffer might go a fair way towards this? Quote Link to comment Share on other sites More sharing options...
welshwizard Posted March 11, 2014 Report Share Posted March 11, 2014 Just out of interest as for my own 12 gauge mag loads have you tried the pattern with a tighter choke i.e. 3/4 perhaps as you are testing at 50 yds ? Quote Link to comment Share on other sites More sharing options...

Yes it should tighten it up a touch just dont forget with buffer it will put pressure up as its more weight in the shot cup And watch the wind for blowing buffer back in your face it dont taste very nice and makes your eyes sting Quote Link to comment Share on other sites More sharing options...

I will however drop a few pellets Quote Link to comment Share on other sites More sharing options...

I suspect buffer might go a fair way towards this? I went down this road a few years ago loading 5mm lead in the 10g for fox shooting and found A STEEL and 381 very poor patterning . blue dot and longshot with buffer gave very tight patterns though I was using a much tighter choke than you if you can get some blue dot try this load from bpi 10g fed case cci 209( I used a cx2000) 38 grains blue dot bpd10 wad 21/4oz lead shot buffer (no weight given) 6 point crimp 10.000psi 1200 fps loadnotes/application. long range,large shot coyote load Quote Link to comment Share on other sites More sharing options...
