i have the jelly head for my moss 835 ulti-mag and i shot it last week with new federal hvywts, and rem hevi shot. all were #5 shot and 3 and 3-1/2" mags.

It completely destroyed the turkeyhead and neck on target at 30 with all three loads. At 40 yds, between 28-45 in vital areas with all three. I'm good to go..

New fed heavyweights kicked like a mule compared to the rem hevi-shot in 3-1/2".
