If anybody can track down one of those Dram Equivalent/Muzzle Velocity Tables, can you post it here?

I have some shells that don't have muzzle velocity listed, but one box said 24 gram/3-3/4 dram equivalent, and another box said 1 oz/Max dram equivalent.

I suspect they're pretty racy loads. Just curious what the chart says they should be.

the link above is the best i could find after 30 minutes of searching the internet. I did a little rough calculating based on this chart and i would guess that your 24 gram load is probably some where around 1500FPS. please dont take my calculations too serious for they are only a rough claculation.

page 102 and 103 of the Lyman Reloading Handbook 5th edition has the table BUT no listing for 24gram 3 3/4 dram but 1oz 3 3/4 is 1400 fps and the max 1oz load is 4 1/2 drams which is 1510 fps so BYG is probably pretty damn close.

Chip

Do they have a reference for 7/8 ounce 3-3/4 dram?

I'm not able to access a copy of Lyman's. Far away from home, you know.

No 1oz is as low as it goes in 12 ga and to add a further wrinkle the Dram Equivalent is different for different gauges. IE 12ga 1oz 3dram = 1235 , 16ga 1oz 3dram = 1275 , 20ga 1oz 3dram = 1275
