I have a couple of pounds of 777 left over from muzzle loaders I used to hunt with. It seems I read somewhere that I could use Hodgon Triple Seven for shotguns, specifically the 410. I have an H&R single shot that I'd like to try using Triple Seven in. This would be something for the grandkids to plink with.
I did an internet search and found nothing on this.
Does any one there have a link to data?
Thank you for your time.
