TONY R Posted August 22, 2016 Report Share Posted August 22, 2016 Any of these Metro loads any help. Heavy Goose Federal 3" 12 Guage Hull Federal 209-A Primer 19 grs Alliant "Steel" Powder 1 1/4 oz. T Steel or other type of heavy, non-toxic shot 3" steel shot wad, or BP Pattern Driver MV 983 fps Pattern with Modified Choke: 89% @ 40 Yards Goose / Duck 2 3/4" Federal 12 Gauge Hull Federal 209-A Primer 20 grs Herco Powder 1 1/4 oz. T Steel(Goose) or BB Steel (Duck) MV 869 fps Pattern with Modified Choke: 91.8% @ 40 Yards New 20 Gauge Data (Use with Metro Gun 20 Gauge Adapter System) Federal 3" 20 Gauge Hull 209 Primer (Any) 12 grs Hodgdon "Longshot" Powder RS or any other steel shot wad Felt under shot wad, as required for correct crimp MV 887 fps Pattern with Modified Choke: 88% @ 40 yards IMPORTANT! All of these loads are reduced-powder charges that are enough to allow for changes in wad, shot type, and under shot wads to adjust for correct crimp levels. DO NOT exceed these powder amounts as it will greatly increase sound, and pressure will become unstable. Be sure you understand the principles of handloading before you attempt to reload any ammunition. Any deviation from these principles can result in SERIOUS INJURY OR DEATH!

TONY R Posted August 22, 2016 Report Share Posted August 22, 2016 (edited) I will give my thinking on a 35 gram load based around the first load above, Its hot federal 209A Its small volume of powder a big charge of shot so igtnition even with the older lots of A steel should acctualy be ok, but the claimed velocity could go up to 1000 or 1050, so you might just get a few more FPS less recoil ...not that it will kick hard anyway... but most of all you would get a little more pressure with a LBC 43 and a 70mm gordon case this will help maintain the designed speed and pressure if you dropped a gram off the shot weight to get you to your 35 grain, And the 35 gram will fit nicer in the LBC wad with the big shot, the full 36 in that load will be a bit of a squeze in an LBC 43 even with set back taken into account, and im thinking the LBC and 19 grain A steel charge should be ideal for a frangible disc closure, and all thhis will be fine in a normal 70mm gun. And for an after thought you could swap the Federal 209A for a CCI209M similar performance and helped by the gordson case too, Even A CX2000 should not be that bad esspecialy in A steel lots from 18 and up its Eassier ignition in the latter lots. Not tried to fit this in but i recon it would work, but not sure you could have quite enough room with a TPS in the gordon and a Full 36 gram payload of Ts im thinking in a gordon you would struggle a bit. But never tried any of this, but its what i would do, ill load a few put them through the crusher let you know what they make . pressure and ill crono them at 9foot.

muncher Posted August 22, 2016 Report Share Posted August 22, 2016 There was a move to this over in USA a while back for built up areas etc . Quote Link to comment Share on other sites More sharing options...
TONY R Posted August 22, 2016 Report Share Posted August 22, 2016 There was a move to this over in USA a while back for built up areas etc . To be honest i like speed probably more than most on steel loading if its not flat out, im not that interested in it, but we all know its not needed and two sizes or even three sizes more steel in the bbig cases at lower speeds will do the job, and it kind of makes use of the 3.5 inch 12s extra case volume, this could be where its if real merit rater than using all that pressure for 42 gram at 1450fps , why not bigger shot at a thousand and 48 gram, at im guessing a slightly lower pressure. Longer wads needed to make full use of im guessing around 17 grain A Steel load. No idea if it will work out in the field, but it sure will save on hard to get powder charges. PS i do know a 36 gram 19 grain sub load cycles my MP153 without any adjustment from the Factory possition. Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted August 22, 2016 Report Share Posted August 22, 2016 Cheers lads. I got a guy asking about this. I would have gone the green dot route but each to there own. If I can get A1 to do 42g lead subsonic, it would do 36g steel. Cheers. X Quote Link to comment Share on other sites More sharing options...

X I did try a 3 inch load as above, a wile ago but i dont reload for subsonic and as in Brezneys warning they are reduced loads, and they can get risky if you go too keene on reduction, i dont know enough about the charecteristics a propelent needs to be able to from cold advise whats a suitable powder or powder charge, for safe subsonics, moving too far away from the above data from brezney a known subsonic bloke, im a bit uncomfortable to stray far. But im all ears as to what is suposed to work and more important why it works. Any advice would be good. Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted August 23, 2016 Report Share Posted August 23, 2016 i am more in the smaller charges of efficient powder, hence my 13grain 1oz subsonics with the fastest powder i could humainly find. Quote Link to comment Share on other sites More sharing options...
pestcontrol1 Posted August 26, 2016 Report Share Posted August 26, 2016 I have a light subsonic load with vec AS in steel that i loaded up thinking it would be a bit better then it really was lol Quote Link to comment Share on other sites More sharing options...
TONY R Posted August 27, 2016 Report Share Posted August 27, 2016 (edited) I have a light subsonic load with vec AS in steel that i loaded up thinking it would be a bit better then it really was lol Did you load a couple or three sizes bigger with these loads? Im sort of interested in how subsonics would work, with big steel i mean 1050fps is not very fast but when you chronograph factory steel its ok not 1050fps but its pretty pathetic but it kills ok and with normal sized shot for steel, a couple of hundred fps lower and three shot sizes in an heavy old load might just work ok. Pyrodex RS maybe. :lol: Edited August 27, 2016 by TONY R Quote Link to comment Share on other sites More sharing options...
