Im trying to figure what different drams are available for 12 and 20ga shells, and what dram refers to max loads? Thanks.

Scott,

Good Luck! I hate those confusing things.

From Lyman's 4th. (lead shot only), the highest 12 ga. listed is 4 1/2 drams. With a 1 1/8 ounce payload this should give 1475 fps. The highest 20 ga dram equiv. listed is 3 1/4. With 7/8 oz of shot this should be a 1320 fps load. Of course less shot more velocity; more shot lower velocity.

The highest factory loads listed are 4 dram in 12 ga. and 2 3/4 dram in the 20. However, remember that Lyman's 4th. was published in 1995.

here is good link for Drams Equivalent.
It a velocity/charge weight ratio.

That is PERFECT. Thanks vary much, i printed it up and will treasure it for life now. Im trying to figure what loads to buy to trying shooting in my 20 ga semi, but i dont want to get the lightest loads to avoid jamming, and also i dont want to have to spend $10 a box for heavier loads to try. Thanks again, Scott

Scott,

Even my Dad's old Winchester 1400 would take anything you fed it. Just buy something in your price range...
