I have one of the synthetic stocked 12ga/.30-30's.
I have see-thru rings and a 1.5-5x Tasco EXP scope.
I have Carlson choke tubes for riffled slugs, steel shot & turkey loads. All the chokes extend about 3/4" past the barrel muzzle.
I've also installed a Pachymyer Decelerator recoil pad (the stock pad cracked due, I assume, to using heavy 3" shotgun loads).
I also have an MCA chamber adapter so I can shoot 32 pistol rounds through the .30-30 rifle barrel.
I'm using Hornady LEVERevolution 160 gr ammo for the extra power & velocity it offers (it's flatter trajectory isn't something I need).
I don't think that I've ever made a shot with it at over 75 yards (and most have been at much shorter distances).
Yes, it's not the lightest gun around, but I really appreciate the weight whenever I use a 3" high power turkey load, or the 1-3/8 oz full power Remington Buckhammer slugs. Boy do they kick so much more than the .30-30 does!!
Okay; not everyone appreciates it's 'industrial' looks, but it simply shrugs off living outside in sub-zero weather for days/weeks on end, being dried by campfires, getting submerged during canoe portages, or any other abuse I can devise for it & me to endure.
I often winter camp using a tarp and more than once I've woken up to find it buried under 6" of snow. Brush it off, go find breakfast.
Downsides? Well, I hunt solo from a 52 lb Kevlar canoe, and the 'kick' from a 3" shell can rock it a fair bit (I try not to take broadside shots, but the waterfowl don't always indulge me).
Improvements? Well, a swing away scope mount would be nice, and I'd also like molded in shell holders in the stock (I'm just weird).
Would I buy another one? Setting aside my comments below, in a heartbeat!
Based on what they are currently changing hands for, mine has appreciated in value about 5 times! Not a bad gun investment at all.
But, planning for a future move, I'd like a bit more power than the .30-30 offers (I've started a few threads around this very issue).
I'd gladly pay a fairly significant sum for a equally indestructible combo gun with a 3" chambered 12ga (that had screw in chokes) mated to a 'bigger' .30 caliber rimmed cartridge with the rifle barrel on TOP of the shotgun barrel (not UNDER it).
But no firearms manufacturer evidently seems to think such a combo gun setup can be made to function reliably/long term.
However, I recently saw a Valmet 412 .308 double rifle with the TOP barrel re-chambered to .300 Win Mag on Gunbroker; so I perhaps my desired configuration isn't as troublesome as many seem to make out.
Best regards,
Steve
