Thread: Damn It! Lost load data.

This from a practical old bugger that doesn’t know anything about loading. Reverse engineer one of your existing shot shells.

Update: Still couldn't find the data I was looking for but I've recently been offered a Lee 1oz slug mold and some Unique powder, plenty of data for the slug and powder but the data data is only for 1450fps @ 10,000psi, I've love to make a reduced load at around 1200fps with less pressure and less recoil. Anyone tried this?

Why can't you just reduce the charge until you get the velocity you want?
Or interchange data for any 1 oz shot load at the velocity you want?
With a plastic wad it shouldn't matter wether you are pushing 1 oz of shot down the barrel or a 1 oz slug.

This is the state of a wad from recent testing of slugs loaded as per ADI's load data. This wad stayed with the slug until it hit the 25m target and bounced off. There's a clear indentation caused by the slugs base.

the wads I used were White, without the felt base I had the indentation like yours. Use a felt/cork base & trim the petals back to the shoulder of the slug, this improved the accuracy of mine heaps. 21grains felt like 1200-1225fps (just cycling the action on the Remington 1187) & 21.8 feels like 1300-1330fps (feels like the fast trap loads I use & blows up rabbits great at 50yds). I use a fold crimp. I shoot Trap & Skeet so compare recoil & speed to the pattern sheet, at 50m the with 21.8grain the slug goes through the wooden pallet & folds the waratah in half almost cutting it off.

@Bob Da Browning thanks for your input. I did have some homemade cork nitrocards but didn't use them, Pushed the slug slighty too high up the hull and couldn't get a decent foldcrimp. Was that 21 grains of AP70N?

@Bob Da Browning I tried 21gn of AS50n, still kicked a bit. I shot a three shot group @ 50m, two hit 2" apart but one hit 5" low, possible flyer or something wrong with load. I tried a reduced load of 26gn down from ADI's recommend 28.1gn, recoil felt a lot worst, knocked the wind out of me a bit but a nice 2" group

I used AS50N as I couldnt get AP70

fill the cavity in base of slug with something like silicon..it wont grab the wad the same anymore
