    Yes considerable more felt recoil i.e. they are hotter. As for the caps question i revert back to the fact that the Martin's $100,000 was won last year from the 27 with 2 3/4 dram federals. Just say'n..................

    Consider any two 1 1/8 ounce target shells that are essentially identical. Except... one is a 3 dram shell running at approx. 1200 feet per second (fps). The other is 2 3/4 dram who's speed is about 1150 fps.

    Conventional wisdom holds the 3 dram (1200 fps) shell is 'better' for handicap - particularly long range handicap.

    Three dram shells will, without question, result in more recoil than slightly slower 2 3/4 dram shells.

    If you re-load try this in any hull, 18 Grs Green Dot it is a target crunching, smoking target load from anywhere on the trap line and you have to get used to the speed of it. I have gotten 99s and a 100 in Hdcp with it and quite a few 200s in singles in my earlier years of shooting when my reflexes were good.

    I now load Promo to those speeds as money is tight. I save about $20.00 in powder expenses.

    To tell the truth, I can rarely, if ever, tell any difference between the two, providing the weight of the shot is the same. Not a real difference in recoil OR performance. There also seems to be a bit of variation in the velocities of either. You could end up with a slow 3 Dram load or a fast 2 3/4 Dram. I've chronographed quite a few factory loads over the years and there is enough variation sometimes that the line between the two isn't that well defined. Shot quality seems to be a bigger concern, but then, there's always the argument about shot size to worry about. Maybe even the one about 1oz or 1 1/8 oz. Shoot what works best for you, at the yardages you are shooting at. Years ago I shot nothing but 3 Dram 7 1/2s, because that's what they had at the club and it worked. Today I roll my own and can make whatever I think works best.

    My scale dose't indicate drams. Where do I buy a scale that does so I can load the three dram loads in case I ever become handicapped.

    Letts' clumsly attempt at humor highlights a valid point. Drams or more accurately, dram equivalent, refers to an archaic measurement from black-powder days.

    A given volume of black powder would push a specified shotshell payload at a particular speed. Three drams of black powder would push 1 1/8 ounce of shot at approx. 1200 fps. Any modern factory load (or reload using smokeless powder) that pushes 1 1/8 ounce at 1200 fps is said to be a 3 dram load.

    IMHO, it would be less confusing if shells simply listed the velocity and dropped the references to drams.

    at 40 yds it means the #8 shot will get there out of a 3dram shell the same time the 7.5 gets there out of a 2-3/4 shell, if set off same time
