Conerned Hunter, I don't think I've ever loaded 100 grain bullets in a 7mm anything. I think the lightest bullet I've ever loaded is a 7mm 120 grain. Sorry I can't help.
Concerned hunter,
Who makes 100 gr. in 7mm, I tried the 120 gr., they didn't work very well for me. I think anything under 140 gr. is light for a 7mag.
Be safe, have fun!
P.S. Dan I found the glasses, go ahead with the deal tell me when and were.
Sierra makes 100 gr. hp's and I was trying to load some for varmints but can't get a group. That is with the lightest load. But I was also thinking that they could be too light.
concerned Hunter, I've checked my data for as far back as 1974. The closest I can come is a 110 grain load. It shows 64.5 grains of H 380, RP brass, Winchester LR primer. It indicates that the group was about 1/2" and the velocity around 3500 fps. That's all I have that even comes close.
