Slider?

Kinda weird sounding, but my bh 45 colt shoots to the right at 10 yds. At 20, it shoots closer to point of aim. What might be going on?

70Dart340 will become famous soon enough
I would check to see if the barrel is clocked correctly.

Did this happen once? Or is it repeatable?

The most likely thing I can think of if it only happened once was that you had the revolver canted at one distance and not at the other. But the chances of that happening in a repeatable manner are slim.

Get another shooter to try it. I'm thinking you changed your grip or sight picture. That bullet isn't flying a curved trajectory in the horizontal plane, just the vertical.

I'm thinking my finger and the trigger are not on the same page. Try some more today.

Next time this happens, and if there isnt a second shooter to try it, take a rest and see if it does the same when your hands and wrist are supported.

I could go into a discussion of the coriolis effect where a large bullets tends to curve in the direction of the spin (like a slider), but you're not shooting at 2000 yds. If you have a cylinder throat, or two, that are tighter or looser than the others that might cause those rounds to have a different point of impact, but if you are having consistent groups in different places than it is something else. The other posters have given you a simple test, simple is always a good place to start.

The only “spin” that comes into play with the Coriolis effect is the spin of the earth, not the bullet. The angle of deflect will depend on where it’s taking place......in the Northern or Southern Hemisphere, or shooting East to West or West to East.

Sorry to say ... but I 'think' it must be the shooter. Anytime I am 'off' at 10Ys, it going to be 'way' off at 25Ys and beyond. Normally when I adjust my sights, I start short (say 15Ys) and adjust to POA. Then test at 25Y for final adjustment as I know it will land on the paper plate (my cheap normal test target)!

Shot 30 rds today from a rest at 20 yds. It grouped good for me and my eyes, but it shoots about 4 inches right from poa with the rear blade all the way to the left. I don't think I'm pulling it because it was rested well on bags. Sent Ruger an e-mail and maybe I'll hear something soon. Another thing is the cylinder base pin seems like it's in a bind when swapping cylinders. Comes out fine, but I have to give it slight pull to the right before it seats.

No more discussion on the Coriolis Efffect?

I'm pretty sure that we ruled out spin drift and coriolis effect.

Going back to Ruger for a look-see tomorrow. Lot cheaper than a trip to Quito I hope. The closer I examine the front sight, it seems tilted to the left very slightly.

Good, because the statement made didn’t support reality.
