.460 shots going high, and higher the farther you shoot.

.460 Magnum · Jul 27, 2017

Hi guys. I was just shooting yesterday off of the shooting bench. I sighted my .460 in at 20 yards. I was getting good groups. Then I backed the shooting bench up to 30 yards. Never hit the target!! The shoots where that high!! Then I moved the shooting bench in to 15 yards, it then was hitting 2-3" low!! So 20 yards dead on, 15 yards 2-3" low, and 25-30 3-5" high. Should I set the shooting bench up at 50 yards, zero it, and then move in to 30-40 yards and see where it hits? Also, have any of you guys went with the .250" front sight, Vs the stock .208" front sight? I have the .460 8.38" btw. Wondering if the slightly higher front sight would fix this problem. Also I will add, .45 colts shoot well, a long with .454 rounds. What are your thoughts on this problem? Thanks guys

So are you having the elevation problem with the .45LC's and .454 Casull's too... or just with the .460 Magnum loads? I would stick to one load at a time to eliminate these sorts of variables and questions first...

It shoots fine with .45 colt rounds. Really have not tried the .454 rounds much. But I have been using the .460 loads a lot. And that is what I have found out so far in shooting them. I am using a stable shooting bench also.
Do you have any thoughts on this?

Put the taller front sight in. I had to do the same with my 500mag as it was printing high at longer distances.

Did that fix you problem? So far it just seems to shoot high with the .460 rounds, and keeps going higher the father the yardage. I was hoping Ruggy would chime in. Thanks 9mmsubgun!! I did do some searching and other people with .460s and .500s are going with the .250 front sight, vs keeping the stock height.

What weight bullet/ammo are you shooting in the 460? 200gr Hornady FTX ?

The bullet starts dropping....

The bullet starts dropping the moment it leaves the barrel and doesn't stop until it hits the ground. Were your bullets heavier than the ones you are used to shooting. I put some extra heavy bullets in my 9mm and from 10 yards away I shot OVER the target.

I've seen similar results but I thought it was because of the scope being higher than the bore. If I remember correctly a .270 Winchester sighted in at 17 yards will hit something like 2 inches high at 100. I know this is no help because you are using iron sights.

The first thought that comes to mind for me is Recoil Management. As in HOW are you managing the revolver during recoil.

My first longer barreled revolver was a 6 1/2 inch model 610 and I learned rather quickly that longer barrels magnify any inconsistencies in how the handgun is controlled while the bullet is transiting the barrel. In one experiment I allowed the barrel to rise with almost no restraint and compared that to shooting with the muzzle rise restrained. BTW, both methods were done while shooting off a sandbag. At 25 yards the result was an eye opener, the unrestrained shots had a POI 12 INCHES higher than the shots where muzzle rise was restrained.

It took a lot of practice but I finally did manage to get that 610 to group at 1 1/2 inch at 25 yards off a rest but even after all that practice and many years since I still shoot shorter barreled handguns better than the longer barrels. Of course knowing this also means I don't spend a lot of time shooting with longer barrels so that really isn't a surprise. However my point is that what you are observing may simply be a result of how well you manage the muzzle rise while the bullet is transiting the barrel.

Yep, in this case I believe it's all about the recoil. I'll bet if you shoot some lighter weight bullets you'll print lower.

It is all about ballistics.

This is a ballistic program for rifle, but the principle is the same.

I am using Winchester 230gr copper bullets with a lead core. Nickel star line brass, with 40 grs of H 110 powder ( minimum requirement is 39grs). They are handloads. I bought 200 of the Winchester bullets to put in the .460 cases for just practice rounds. I will be using 250 gr barnes bullets in the .460 cases this year for deer hunting, if I can find out why the bullets are going high.

I use a firm grip, that is for sure, lol. I do notice when I fire, the barrel really do not rise very much, mostly just pushes back into my hand. The compensator helps that out. It is weird though, once I get it sighted in for a certain yardage, it gets wicked good groups. All the shots are right there, then you back up 5 yards, and the shots go 3-4" higher. I really do not know what to say about this problem.

The bullets where 230 grs I was using. Other people that own the .460s said to stay away from the 200gr hornady rounds, way to fast, Forcing cone erosion, top strap cutting. Plus I do not like the way those bullet hold up, and shoot, lol. I love the barnes 250gr bullets. I will be using those for this deer hunting if I can get this problem fixed with the shots going high.

.460 Magnum · Jul 28, 2017

Do you guys have any more suggestions on what I could try different? Or on what the problem could be? Then next time I shoot I am going to take pictures of how it is shooting, and post it up on here. Thank you guys for all the help!! I will keep you all up dated if I fix the problem, or find it, haha.

Choose the ONE load you intend to use for hunting, and zero the gun for the distance you intend to hunt at.

You should have a 100-yard package there, and zeroing it at 20 yards won't get you out to where you need to be at longer shots.

If you hunt in dense terrain where max shots will be 50 yards, then zero that ONE load at that distance & learn where you need to hold at 20 & 75.

Your caliber is not a particularly flat shooter, expect an arc.

Regardless of what load you are shooting, a difference of only 5-10 yards should not change POI 5". I wonder if you are resting the gun differently at the different ranges, due to shooting angle. Do you wear glasses? Only asking because I find myself sometimes looking over my glasses when shooting handgun from a bench and that really changes POI. Sometimes the angle of the shot influences whether or not I accidentally look over them at the sights. Your .460 is a fairly flat shooter under 150 yards with bullets of 300 gr or less. I actually sight my .460 at 75 yards with 300 grainers going about 1800 fps. It hits about 3/4 of a inch high @ 50 and about 1 1/2 inches low @ 100.

I would be shooting at a max of 50 yards. So that is where I am going to be shooting from to get it zeroed. I really bought this hand gun for brush hunting, and close range shots.

.460 shots going high, and higher the farther you shoot.
