I use a Hellbender and Gnargali depending on if it a day hunt, overnight or couple days. I add or subtract pockets, sherman, or OGL depending on the situation. Works very well for me

I've used Tyvek, space blanket, contractor bag, and a 5'x5' tarp. I've been carrying the tarp more because it can double as a small windbreaker or shelter in an emergency.
We've hunted Upstate New York way before it went to rifles, I've shot smoothbore slug guns with Remington, Winchester, Federal, and Brenneke Slugs. Just have to find what your gun likes. My Dad shot a buck last year with the Federal Truball in his Browning 2000 at 75 yards. They seem to shoot...
IMR 4350 is the powder I started reloading with 30 years ago. It shoots good in everything from 6.5 to .338 for me. I've wanted to experiment with other more "reasonably priced" powders but I would burn through a couple pounds of powder finding new loads,
I have done it for years, nothing worst than being 3 miles from the truck and got a barrel full of snow or mud. I tried the painters tape one year just so i didn't have any residue on the end of the barrel but went back to electrical tape. No POI change and its cheap insurance.
