Just got a new Encore. Barrel has adjustable sights. I loaded some cartridges with 405 grain Montanna Precision swaged bullets at 1450 feet per second.. I was hoping for a mild target load. With the factory iron sights set at the lowest position the point of impact is an incredible 18 inches high at 25 yards. Windage is ok but it is consistently 18 inches high. What am I doing wrong?
 
I would contact T/C about it. Sounds like a problem with the barrel or maybe the sights on the barrel.

That doesn't seem like an outrageous load to me.
 
My Encore shoots high with the factory iron sights at 50 yards. It is spot on at 100 yards with the lowest setting.

I think they are anticipating the arc of a 45 70 bullet and giving you enough adjustment to get the bullet out to 150 or 200 yards.

Have you tried the round at 100 yards??
 
Do you have the same problem with factory loads?

You've probably already seen this site.

My TC shoots high after (if):

1) headspace is too long (not a prob with your load)
2) barrel gets hot
3) load is hot
4) cleaning with copper cleaner instead of just hoppes.

TC's seems to like a fouled, cool barrel. Try it with factory loads. Colt is on the right track too.
 
I'd wager that the load T/C assumes you will use for the .45-70 is the 300gr HP factory ammo at about 1800-fps. My Encore Katahdin .45-70 will NOT zero with factory 405s, but no problem with 300s at 1800-2000 fps.

What you are experiencing is indeed bullet impact change due to recoil. I know, I know, 50% of people believe that the recoil doesn't affect bullet flight. Well, it does, especially at the low speeds of .45-70 loads. Your 300gr loads will zip out much quicker, while the barrel is still lower in its recoil track. Thusly, they will go to zero. Now, toss a bigger, slower chunk of lead, and your muzzle is further elevated at exit (more barrel dwell time). Presto! 18" high. My .45-70 barrel will throw 405s about 18-24" high at 50 yards when zeroed with 300s.

That, and I think T/C has a hard time figuring out how tall to make their front sights. My .50-caliber muzzleloader barrel shot about 6-10" high at 50 yards with a 100gr load and a 240/250 sabot. Of course, it went to zero with the faster 150gr load, but I don't want to put up with that kind of kick.
