shooting high



Log in to see fewer ads
Can anybody out there figure how much I need to remove from the front sight ? Shooting 2" high at 10 yards. The pistol is RST4.
/The distance between sights is 7.250
I'm sorry. I was thinking about the sight being too high and I wrote that it was shooting high. It actually shoots low. My apologies.

Do NOT remove any height from the front sight. That will make the gun shoot higher, yet, not lower. You can remove a bit from the fixed rear sight to make it shoot lower. Best of luck.

What Rimfiregal said.

Also, before removing material anywhere - check the chamber for carbon ring. When my accuracy starts to drift from POA, I know it's time for a better cleaning. (I have fixed sights too.)

You could make a new front sight blade from flat stock. Also, VQ makes a replacement blade that's taller.

After confirming that this isn't a sight alignment/sight picture problem the mathematical answer would be to remove .040 inches to gain 2 inches of elevation at 10 yards... for that ammunition.

Have you tried other ammunition with similar results?

For raising POI 2", I would suggest you put a piece of masking tape on the front sight about 1/32" below the top and align the rear sight to the tape. Lower it a bit if still low, or raise it if POI is now high. Once the POI is on according to the tape, you will know how much material needs removed.

My MKII standard needed a bit less and my MKIII standard needed a bit more.

Thank you all for your help. I appreciate you taking the time to give me a hand. Without advice, I was going to take.010 and give her a try. And again as necessary. Nice to have a neighborhood to look for. I will also incorporate the tape trick. And I do intend to try at least a couple more types of ammo first,just in case. At work,and to my shooting pals , I brag on RC people being knowledgeable and helpful.

A fixed sighted pistol is going to shoot point of aim at a certain distance. I doubt that is 10 yards. Unless you are going to only shoot at 10 yards, perhaps that distance should be determined. Typically a handgun sighted in at 25 yards would shoot low at 10 . Think bullet trajectory. Altering the sights for 10 yards would affect sighting at longer distances.

Poa/poi

Only being a defense/plinking hand gunner, but a bench shooter with longies, I'm thinking how lucky the OP is if
he/she has consistent POI at *any* specific distance.

Then again, if the POI is LOW at 10 yds, I guess I can see the desire to mechanically move the elevation.

If the windage is on the money, the POA can be easily adjusted from shot to shot.

Then again, you don't want to have to hold "two feet" high at 100 yards...Yikes!!!

You are of course correct about any gun being sighted to a specific distance. With fixed sights, you must change your POA and/or technique to adjust to targets at a different distance.

Most pistol shooters I see at my indoor range set the target to between 7 and 20 feet. They seem to have a hard time keeping POI within 10" of bull. It's mainly rifle shooters and pistol shooters with scopes that shoot 20-25 yds.

I adjusted my front sight to be dead-on at 15 yds. It's pretty rare for me to shoot any closer, but it's pretty easy to put the front sight a little above the rear one for a target that close. When I move the (5") target out to 25 yards, it's pretty hard to estimate where the center of the target is with iron sights. So I adjust my hold to be slightly more 6 o'clock.

It really becomes second nature as round count goes up. I don't think it would ever become "easy" to shoot 10-15 yard targets with an iron sight pistol set up for dead-on at 25 yds. It's always easier to aim a little low than a little high.

If you consider the trajectory of a bullet at about 1000 fps the drop is roughly 2" give or take out to 50 yds. A ballistics program can give you a more specific trajectory. I shoot at 25 and 50 yds with iron sights, and with at most, 2-3 clicks correction (0.5"?) - usually I don't bother. The bullet would strike lower at under 25 yds, since it is coming up at 25, and dropping back down out to 50 yds.

So, I would suggest perhaps, 0.5" low at 10 yds., which would serve you out to 50. What size groups are you shooting? If you are shooting off-hand, you likely have more variability in your hold and precise sight settings are harder to determine. For example, if you are shooting 2" groups at 10 yds, what is 1/2" among friends?

Good shooting.

Fixed sights? Shooting 2" low? No problem. Just aim 2" higher. That's been a workable solution since long before I was born, and I was born before most of you here.

I'd bench it and shoot targets at 25 yards and go from there
