My secret to getting tighter groups than-that at 100 yards offhand, is limiting the blackpowder to 80gr with 300gr bullet and 90gr blackpowder with a bullet that 200 to 240gr.

I may think I'm just as steady-handed firing with something like 105gr, but I'm really not. I can duplicate everything using 80 - then 105, but I always get better target holes with 80gr of powder. My only explanation for that is in my forend hold and I've never used the secured strap-hold to this day.

I was taught it by a military instructor years ago and never applied it to my range or hunting rituals.
