    It’s a cold, nasty, wintry day here in western NY....so here goes. Take two boxes of 1-1/8 oz. 12 gauge trap loads, reloaded identically; with the exception that one box contains #7-1/2 shot, and the other #8 shot. Here’s the question. Will one produce more noticeable felt recoil than the other? Charts and graphs are willingly acceptable. God, I wish it would warm up so we could all go shoot…

    Fire!

    Don't need a chart...

    1 1/8 oz is 1 1/8 oz whether they are 7 1/2s or 8s IF the shot is dropped by weight.

    Since hobby presses drop shot by volume, from the same bushing the load of 8 shot will weight very slightly more than the load of 7 1/2 shot because the 8 shot is a bit smaller and there will be less void space between the pellets. Noticeable difference in recoil? I think not.

    Of course it depends on what choke is in the gun.......

    Same shot manufacturer (Eagle), same powder (Promo), same powder bushing (MEC), same wad (CB), same hull (REM GC), same primer (W-209), same gun (K-80), and same choke tube (K-3). Hell, I even started on the same post! Everything was totally identical except for shot size, so weigh in...

    Tron - please try to stay with the program.

    Hell, they were probably 4-hole the way the wind was blowing this morning...

    Sorry.... But the sharper angles of the 3 hole targets and the rpm difference can change felt recoil....so I've read.

    7 1/2s fly farther, and every action has an opposite and equal reaction, so 7 1/2s will kick more. Or maybe not. Mark

    Yes winter shooting can can be hard. I live in Northern Il. to day at the club it did not get above 22 degrees.

    If you can feel the differance between 7 1/2 and 8 shot 1+1/8 same load, I think your mind is not on the target and good break or bad break. Yes there may be a small amount more of # 8 shot but ????.

    Tell us what recoiled more 7 1/2 or # 8

    If you drop a pound of feathers tightly bound and a pound of lead from 100 feet in height the lead will hit first because of the air resistance on the larger 1 pound feathers, unless you do it in a Vacuum, then they will hit equally.

    As we await actual "scientific data", I'll tell you what my experience was this morning. I normally shoot #8s for singles, even in the winter. Today I shot the first round using the box of 7-1/2s and immediately noticed a difference in felt recoil. They felt like a box of 3 dram loads through the entire round, instead of the normal "push" like I usually get. I dropped one, which was helped by the strong wind from behind me. The next round was with the box of #8s and they felt totally normal. I broke all of those, so contrary to John G's theory, I think my mind was on the targets, but I still can't figure out the noticeable difference in the recoil. Strange..

    I really would like to see some data from someone on this subject..

    8 or 71/2 don't have near the recoil most loads with 4&5s. But then again the 4&5s aren't legal ATA trap loads. ;)

    The heavier the "pay load" the more recoil. Pay load is
    described as the weight of the powder, wad and shot.
    I doubt you could feel any difference between 7.5 or 8's.

    See chart in lower left hand corner. 7 1/2s go further than 8s. Mark
