impala59 Posted January 12, 2016 Report Share Posted January 12, 2016 Has anyone tried a light, say 24 gram #6 shot fibre wad load? I ask as a fellow shooter over the weekend was knocking down the plates ok with a 24gm cartridge, his only problem being cycling his semi. As I shoot a pump the cycling issue is not there and reduced pressure and felt recoil would be an advantage (I need all the help I can get!) would such a load work better in a 65,67 or 70mm case? I am getting the old Loadall out of mothballs and I would be grateful for any data, powder recommendations etc Thanks Roland Quote Link to comment Share on other sites More sharing options...
hatsanmad Posted January 12, 2016 Report Share Posted January 12, 2016 The smallest you can load on a loadall is 70mm tried loading 67mm and it dont crimp them quite right Quote Link to comment Share on other sites More sharing options...
ChAoS Posted January 12, 2016 Report Share Posted January 12, 2016 Has anyone tried a light, say 24 gram #6 shot fibre wad load? The only trouble with light loads is that they may not make the minimum "power factor" (ie, M x V, better known as "momentum") requirements for "serious" PSGing. Regards, Mark.

Regards, Mark. Roger that Mark, am just feeling my way back into PSG, gently and slowly! The "race" guns in open class have certainly changed, although the tech revolution still does not encompass the human element! It was reassuring to watch open classers forget o take their 2nd 15 round mag or drop a full mag in the mud. Getting back into it on sect 2 initially, I hope to relearn shot count awareness etc. The smallest you can load on a loadall is 70mm tried loading 67mm and it dont crimp them quite right Understood, Would be cutting, over shot card and rolling the shorter cases, I used to love making rolled carts, there's something more creative about them in my book Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted January 13, 2016 Report Share Posted January 13, 2016 How on earth can you feel reduced pressure? Just use a 32g load. Quote Link to comment Share on other sites More sharing options...
impala59 Posted January 13, 2016 Author Report Share Posted January 13, 2016 (edited) Sorry Cookoff my bad grammar! Reduced felt recoil (could do better) (I've heard that before!) ....edit... The pressure drop I was looking for was to do with fail to extract problems on Ithaca Mod 37 Edited January 13, 2016 by impala59 Quote Link to comment Share on other sites More sharing options...
rovercoupe Posted January 13, 2016 Report Share Posted January 13, 2016 There is a Vectan as load for 24g in plastic might be in fiber too but not got the sheet to hand, I have been using it in the sxs and semi and had no issues in either, soft but seems to cycle ok.

Breastman Posted January 15, 2016 Report Share Posted January 15, 2016 For IPSC matches you need to achieve a 'power factor' of 480. Power factor is calculated by weight of prjectile(s) in grains x velocity in FPS, divided by 1000. A 24g load is 370 grains, so in order to generate the required power factor it must have a muzzle velocity of at least 1298fps. I doubt a 21g load could be made to qualify as it would need to be going 1485fps!

impala59 Posted January 15, 2016 Author Report Share Posted January 15, 2016 Understood, Breastman, looking initially for practice load, if its good then will chrono for power factor. Love the info return on PW. Quote Link to comment Share on other sites More sharing options...

impala59 Posted January 16, 2016 Author Report Share Posted January 16, 2016 1500 + fps 4mm nitro card Let me know if you cant find it and i will pm you it over Thanks pestcontrol, top info. I found the powder, Clay and Game stock it. Looks like the load to go for! Once again PW the best source of information Appreciated! Quote Link to comment Share on other sites More sharing options...

Breastman Posted January 17, 2016 Report Share Posted January 17, 2016 Absolutely..... Ha ha! I bottomed out of a-level physics with an E grade and that was 18 years ago so I'll pass on that one! However, whatever the physical recoil is I've found to be almost irrelevant as perceived recoil is very subjective. The gun, it's fit, the action type, the clothing the person is wearing and the person themselves can make one persons mule another's pussy cat. I personally can't tell the difference with the recoil between my 3 shotguns and they are all very, very different from one another, but them main thing is they all fit me.

With reloading my mantra is charts and data first, ask questions and weigh.... when an opportunity arises to chrono, take it! Safety First!

Bobby199 Posted January 19, 2016 Report Share Posted January 19, 2016 The smallest you can load on a loadall is 70mm tried loading 67mm and it dont crimp them quite right Could you not just raise the carts up a bit with a little circle of wood or the like underneath? (sorry if this is ludecrous as I know nothing about reloading and can only picutre that bringing the cark closer to the drill press like thing might help with the leverage/ crimping issue) Quote Link to comment Share on other sites More sharing options...
LeadLobber Posted February 20, 2016 Report Share Posted February 20, 2016 ....was to do with fail to extract problems on Ithaca Mod 37 impala59, I too have had extraction problems with my Ithaca M37, now resolved. It seems that they can be sensitive to some European cartridge case rim profiles. A good gunsmith re-profiled and filecut the inside of the extractor and I've not had a problem since. Maybe worth a thought. Great gun though - I don't think I'll ever part with mine. LeadLobber Quote Link to comment Share on other sites More sharing options...
