Ok, I'm here.
I have taken over 100 whitetails, an elk, and many other critters with my 7x30 waters. I fired my first one MANY years ago at a gunsmiths place, and promptly ordered one for myself. I have the 14" bbl. My load is using the 150 grn Nosler Ballistic tip bullets. My load is not "hot" but it is accurate. I use the Hornady reloading manual as my guide to building my reloads. My accuracy is excellent, to where when I do my part, I can get them into 3/4" at 100 yds off the bench. (Sometimes, even less.) The recoil is mild, compared to many other bbls I have. I have shot a few 30-30 bbls, (both 10" & 14") and find MY reloads in my 7x30 Waters MUCH nicer. I fireform my brass from 30-30 cases, and trim to fit. About 4-5 years ago, I found a second bbl in 7x30, with the factory muzzle ports. I have taken it out & tried my reloads in it, only to find it just as accurate, a little louder, but muzzle rise a bit less. Felt recoil is also a bit less. I use Pachmyer grips, that I ground a bit to fit my hands. I use their forearm as well. Those grips help the fell & felt recoil in my opinion.
I have not tried that gun or caliber on a hog,, but if I did, I'd switch bullet types to give me better penetration. The Ballistic-Tip is better suited to other game.
The 30-30 is ok to many, but I've found the 7x30 to be much more enjoyable all around. And the accuracy I've gotten out of my 2 bbls, as well as the 1/2 dozen others I've shot,, all point to a great combination. My Contender in 7x30 is why there are a few others around this area who enjoy theirs as much as I do mine.
