Read this posting if you are thinking long distance muzzleloader.
I have one and it is a very accurate gun. I have shot a large whitetail with it at over 300 yards using my bipod and scope. I would not recommend muzzle loader at that distance for Elk. The bullet looses too much energy and does expand.
I got the V2 LR earlier this year and love it. I was worried that the 30" barrel would make it a little too heavy and bulky but I honestly dont even notice it. It shoots sub MOA at 100yrs. I havent been able to use it at farther distances yet.
I bought the plains rifle this past yea. Great so far. Am still dialing my load but am doing pretty well so far. Shooting 110 gr Blackhorn 209 with Scorpion PT gold 300 grain bullet, crush rib sabot. Am going to try a different sabot to tighten things up. Friend has same rifle but notes the sabot/bullet is tighter in his barrel than appears to be mine so some slight variance there.
I have a scope on it but it is drilled/tapped to be able to put open sights on it. I asked in case I wanted to go to Idaho or CO for a western hunt with it. I had to buy a 209 breechplug for it for consistent ignition but they also make an "open" breech plug to satisfy the ID muzzleloader regulations.
