I was out sighting in my CVA Kodiak and at 50yds its shooting 2inch groups but at 80yds, I couldnt even get on the target. Im shooting 100grains of Pyrodex pellets with Hornady SST 250grn sabots. Would 30yds make that much difference when shooting? What could be some possible solutions? Thanks! in advance.

More than likely hitting to the left or right. I had my winchester sighted dead on @ 50 yards, put 3 into one hole, 75 yards it was 10 inchs to the left. Set up a bigger target and you'll find where its hitting.

Wait on second thought, You could be OVER shooting it. CVA says to sight it 1" high at 50 yards.

At 50yds it hitting to the left of the bullseye so would that mean at 80yds its hitting farther to the left?

Yep. Its amazing at how much it opens up at longer distances.

Do you think using a 1x scope opposed to a 3x makes a difference when sighting in a muzzleloader?

A scope is a aiming device. If you are shooting tight groups at 25 yards, and a scope is put on the rifle, it should then keep you shooting tight groups at 50 yards and further. A 1X scope will produce good tight groups, but not as tight as a scope with magnification. I like the 1X scopes, since they are legal in our muzzleloading season here.

Im here in Nebraska so 1x is all you can use on a ML. I just thought there might be a difference between the two. I went out today and had a nice 10 come in at 30yds and I missed him completely. It was my fault because I didnt take the ML out this year and shoot it. It wasdead on last year but I guess moving it around, some how knocked it out of line.

Think about a pie, and the pie is cut into 8 pieces. As you get closer to the center of the pie all the lines converge, but out at the edge of the pie that are a great distance apart. The closer you are to the muzzle the closer the bullet will be to line of sight, so 50 yards you can be right on, but at 80 or 100 you start getting big deviations, because the arc of the bullet and the line of sight are a long way apart. I always do windage at 25 yards and then sight in for elevation at 100, sighting in 3" high at 100 usually. This makes MPBR (maximum point blank range) with most bullets right around 150 to 180 yards---so just aim and shoot anywhere from 0 to 180 yards with a ML sighted in with this method. Chap Gleason

Bullet may be a little heavey for 100grains of powder. Try shooting a 240gr bullet with 100 grains. May make a dofference. Thats what I shoot and I shoot 1-3 inch groups consistantly up to 100 yards open sights.
