222mark Posted February 11, 2023 Report Share Posted February 11, 2023 I've been loading and shooting 12g, 22grains of AS behind 29g of lead but find them too bumpy in a 6 3/4 pound gun. They was ok in a heavier gun. Will reducing the shot to say 24g have the same effect in reducing the recoil as lowering the powder weight behind 29g of lead? Any ideas.

islandgun Posted February 11, 2023 Report Share Posted February 11, 2023 Sounds a bit iffy to me, i would go with published loads Quote Link to comment Share on other sites More sharing options...
snarepeg Posted February 11, 2023 Report Share Posted February 11, 2023 Should do, might get a bit dirtier but should be less recoil.👍 Quote Link to comment Share on other sites More sharing options...
neutron619 Posted February 11, 2023 Report Share Posted February 11, 2023 Note please that I'm not advising you to do anything at all, but I wouldn't be surprised that if there is a 24g load published for AS that it'll have a slightly heavier powder charge. Not certain without looking, and AS is pretty fast so maybe not, but in general, lighter loads can take and benefit from (a little) more powder. Powders usually have an ideal operating pressure (i.e. there's a minimum amount of any powder in a given case needed just to get the powder to burn properly/completely). If you don't achieve it you can end up with some odd results. Dirty barrels full of unburned flakes is one possibility; squib loads because the powder doesn't ignite properly is another. I have literally had shot roll out of my barrels with some experimental "light loads" and on that basis I advise you to stick to published data. If you load 24g I suspect you'll end up with a softer shooting load but check your barrels for the first few. 20% is quite a payload reduction without compensating for it somehow. You might find 26-27g is still significantly softer on the shoulder but makes for a much better performing cartridge. Quote Link to comment Share on other sites More sharing options...

Cheers Vectans tables for AS with Cheddite\Fiocchi hulls gives 18.8grain to 20.3 grain for 1oz loads for 9000 to 9500 psi. And 1200 to 1250ftsec For 7\8oz loads Vectan AS is in the 17grain range for 1250 and 9,000psi. If you are putting 22grain of AS behind 29g, no wonder they are thumpy. You must be doing 1300ftsec and 10,500 to 11,000psi. Quote Link to comment Share on other sites More sharing options...

I'll try 17 as a starting point and work up. Thanks for all the help and input. Cheers. Quote Link to comment Share on other sites More sharing options...
rbrowning2 Posted February 12, 2023 Report Share Posted February 12, 2023 Years back we could buy from peter lawman? vetctan AS24 (A24) which is what you really need, doubt you will find it now. https://www.nobelsport.it/en/products-en/powders/powder-shotgun-ammunition Quote Link to comment Share on other sites More sharing options...

I used to buy Vectan A1 for homeloading 357's. Was cheap as chips from him and i could pop in when i was working in Northampton. Quote Link to comment Share on other sites More sharing options...

Same as me I used to buy the tubs of cut ends from him 2500-3000 in a tub and all vectan A1 , I still have about 3 kg of A1 left. Quote Link to comment Share on other sites More sharing options...

As a side note - I find it smooth to shoot along with having clean barrels at the end of the day compared to hodgden longshot for example.
