.318 WR shooting high to sights
      #215171 - 21/08/12 03:19 PM

I took my Westley .318 Mauser out on Sunday and it shot 12" high at 100 yds using 250 grain woodliegh's and chronoed at 2315fps. The iron sights used require that the front bead be put all the way down into the rear sight which surrounds the bead nicely. I'd rather not screw with the rear sight. Any other options? I can try downloading it but it really shouldn't need that.

Can you do something with the front sight ?

By the way, what Powder are you using ?


Just on the off chance try these.

Change ONE thing at a time and dont forget the 10% rule.


1. Try a different powder
2. Change Primers
3. Change the seating depth.


Now I know it is very unlikely to make 12 inches of difference
but worth a crack.


Re front sight, what about removing it and getting another dovetailed in - although 12 inches, you might need to do something else as it just may end up looking wrong.

Keep us informed.

Downloading will make it shoot higher. Try a lighter bullet as higher velocity.

Bonanza, I admit I'm not the brightest bulb in the pack but that sounds backwards to me. Can you explain that a little?

12" high at 100 yards is a six o'clock body hold on a large game animal, dropping the round nicely into the vitals. Where do the rounds go at 200 yards ?

These were not varmint rifles or 100 yard range guns but hunting rifles.

Staff Sergeant Brown taught me to use the 6:00 hold back in 1973 at MCRD. How large of a game animal are you shooting? I would like to use it for moose and brown bear and I can use Kentucky windage but I shouldn't have to. I just have to find a load that will work with the sights.

Taller front sight will fix that.

Know where I can buy one like the original or where I can get one made? That would be the best solution as I like the 250 grain bullets.

I agree re not having to hold at 6 O'Clock, especially if snap shooting at something on the run.

Anyone have the formula handy for figuring out the height needed? I can take the measurements and plug them in to find out which one I need to order.

I'd change the front sight myself, if possible.

Reducing the height of the rear sight's flat surface is another option, but I'd probably attempt loading changes, different powder.

You are holding the forend with your left hand as you shoot off a rest, aren't you? Letting the rifle bounce by resting the forend on the bags, can give false elevation to the impact. I now hold all kicking rifles as if I was shooting offhand, and rest the back of that forend hand, on the bags. That way, no matter what position I shoot from, the impact is identical.

As 500Nitro posted above, change one thing at a time with testing in between.

12" high at 100, is too high for a rifle that will be used mostly at 100yards or less. Having to always figure "Now, lets see, how much do I have to hold low" is a recipe for disaster when a fast shot must be taken - bear, moose or deer.

To be used as a serious hunting rifle, the rifle must shoot to the sights.

"Holding 6 o'clock" is fine for paper target shooting where the bullet impact is carefully adjusted for that hold on a pardticular sized bull- as with ISU or other round bullseye handgun shooting.

In my opinion, a 6 o'clock hold is less than useless for game - holding 6 o'clock on a moose, elk, black bear, grizzly, brown bear or sitka deer, ie: animals with different height's from the chest's bottom to the boiler room - too much thinking - exactly how far is it? Is it now 15" high, because I'm now 'about' 130yards instead of 100yards?
THIS is why 12" high at 100yards is no good and change must be made somewhere.

I used a BC of .230. It's possible the Woodleigh has a Bc of over .300, thus, the actual height the bullet obtains, will be greater yet.

I think I need one that figures out how much it will raise the impact point.

I was wondering where 6 o'clock is a charging bear when the bullet is already 3" high, or a sitka deer at 120yards with a bullet that's already 14" high - or was it only 90 - or 140?

Casper

I don't like having to remember to hold differently for different rifles, preferring the bullet to go exactly where aimed.

The reason I don't like 6 O'clock holds was born out to me a year or two ago when clearing a property of Buff.

A Bull Buffalo jumped in front of us and took off across our front flat out to get away across the flood plain. I swung onto it at about 90 yards and dropped it with a head shot. In the heat of the moment, I very much doubt I would have been able to quickly lift the gun up, swing onto it, and through it (for the right lead) and shoot it.

That was with a 318 WR and open sights.


Any time I have to think seriously before shooting like a different hold, different bullet etc, it takes the enjoyment and spontinaity out of it and you can lose it.

I copied this from AR as I don't have my sheet.


Put your particular numbers in this formula and you are good to go.

If you are shooting 6 inches high at 50 yards and there is 24inches between your front and rear sight then
6 x 24 = 144 divided by (50x36=1800) =.08 and that is how much you would need to file the rear sight down or get a front sight .08 higher.

At the velocities you are shooting the bullet spends some time in the bbl as it recoils and the muzzle moves up. Speed up the bullet and it will exit sooner while the muzzle is lower.

I dropped the velocity of my .458 WM to 1500 fps from 2000 fsp and it shot 15" high. I then reduced it to 1000 fps and it shot 3" high.

Weird, I know.

That rifle wasn't originally sighted for the 180 grain load, was it? Have you checked the barrel for bullet weight markings?
