Sirs,
I have a super 16 35 barrel and as we have all learned, barrel length has very little to do with accuracy when scoped. Using iron sights the extra barrel length does allow for longer sight radius that greatly assists in accuracy, but when scoped, all the extra barrel length does is add velocity. In the 35 remington, the velocity loss between a 21 inch barrel and 16 inch is generally less than 100 FPS, not enough for me to quibble over. My folding stock, super 16 35 rem and 45-70 barreled carbines are the handiest big game rifle you will find on the planet. They fit right into a backback or get slung over your shoulder and are only about 2 inches longer than a super 14 handgun. Get to your stand, climb up, unfold the stock and you have a sure fire 150+ yard deer killer using Hornady 180 grain SSP bullets. Super 16 is a great way to go with the 35 rem. My only citicism is that the rig is somewhat muzzle-light when shooting offhand, but you can learn to compensate for that with practise at the range. My 35 barrel has factory sights and I use an old 2.5x Burris fullfield rifle scope in quick release rings, the sights are for back up, the scope though is rock solid and has never failed me yet.
regards,
