Keep checking the contender ads here on Graybeards. Also EBay, Auction Arms, Gun Broker, and the IHMSA website lists barrels. I have all the barrels you listed. My 7-30 is magnaported 14" with scope. Have taken deer with it. My 30-30 is 10" Octagon with highrise rings and Leupold 2x scope. Very quick to pull out and very accurate. Used as back-up here in WA during rainy late seasons. Scope if dry and long range, open sights if scope wet or foggy. Never hit a deer, but shoots great out to 200 on the sillywet animals. Have only shot my 10" max for silhouette. Would be good deer gun out to about 150. My load pushes a 210 cast about 1350. Sometimes the rams go a little slow. This could be my cast bullets, or just not pushing it fast enough. I have 7TCU in 10" 14" and 15" XP-100. Would not be afraid to use any of them on deer out to 200 yards, but they hit where you aim.
Now that my novel has started your eye lids to droop, my vote would be the 30-30 14" with a scope. You can push that Nosler 125 Ballistic tip pretty fast. The Sierra 110 HPs are great for chucks and other varmints. You can use the 165 BT for bigger Mulies, Hogs, etc. Little more versatile than the others, you already have the dies, and don't have to fire-form brass.
Just another nickels worth to add to your bank of knowledge.
