MVA midrange at 1000?

Postby westerner » Fri Jan 24, 2014 12:27 pm

Will a MVA midrange sight mounted on a 74 Sharps reach 1000 yards? A shooting buddy tells me he uses a MVA midrange on his Sharps for 1000 yards. MVA says their midrange sight will not reach 1000.

The only answer is "maybe". It is very very close, but no guarantees. And your front sight has a lot to do with it. (as does your load and a few other things perhaps.

The safe answer is no.

Joe

Here is my Load data and sight setting for Creedmore match in Phoenix :

Load duplex 6 grs reloader 7 under 55.7grs Swiss 3f
530 grain saeco #745 bullet mould

74 shiloh sharps 45-70

MVA soul sight

800 yard - 1.45"
900 yards 1.66"
1000yards- 1.88"

Also says that straight black in a buddies 45-90 is very close to his sight settings.

Well, if you got sight settings in PHX, you know the answer because you have done it. Not computing.

What is your front sight? Does it have a bubble, and is it windage adjustable?

Is your sight also an MVA Soule?
If yours is a different style, your buddy's settings won't work for yours.

Is his sight radius the same as yours?
If yours is longer than his, you are probably out of luck.

To have a hope of reaching 1000 yards with a midrange sight you will need a very low front sight, and a 'short' barrel.
If your front globe has a spirit level, you probably can't reach that far ...

Depends a bunch on the front sight and the load. Using the Shiloh 111 front sight, my 44-77 shooting 480 gr patched bullets 1.50 grease groove takes about 1.60 makes the 1000 yd targets at Raton,Byers and Alliance. So with that would make an MVA midrange viable , but for my 45-70 it would barely make it because most of the time it takes around 1.90 with patched and 200 with greasers.

Thinking about purchasing a new MVA sight. Rifle is, will be 45-90, 30 inch barrel. Don't recognize the front sight. Looks low to me. Might change the front sight too. Rifle has a long range sight on it now. Think I'll get the MR MVA Soule sight for silhouettes. Can switch to the LR sight when shooting LR. Would prefer a MR, if it will work.

If you shoot something like the money bullet there's a pretty decent chance that midrange sight will get to 1000 with a bit of room to spare, but with the postel and "creedmoor" bullets it might not geterdun... Only one way to find out :)

Would like to be able to shoot LR with my cap on the right way. My first Sharps, so don't know for sure if a midrange will let me do it.

There is nothing magic about the money bullet.

Get the midrange and a 200 yd sight setting and I'll be able to give a real good idea about it make it to 1000, but that's the best I can do. Just need that extra data.

I prefer the the midrange sights also but it's too close to the edge for me to force the midrange to 1000 yds on a Sharps, even a big, fast one.

Brent you are absolutely right, there is nothing magical about the money bullet, but it does shoot with a few minutes less elevation, and a few less when the wind picksup, and if a person is wanting a short sight staff to work best then it is advisable to take the bullet proven to use less elevation. :wink:
But as in all things shooting a person needs to see what does and doesn't work for them by trial and error.

If "a few" is 3 or less, maybe. But only maybe, at best. The aerodynamics of PPBs is much overrated by the internet gurus.

Well all I can do is report what my rifles tell me. Usually about 10 minutes less elevation for the patched bullets, and about half the windage, and the "money" bullet style will be a few minutes less in elevation under that.. But that's gathered info from a lot of rounds down range with both slicks and greasers shot during the same range session, for practical experience and comparison.
And gathered from that hands on experience if I was in Joe's position looking to make a midrange sight work at 1000 yds, I'm going to have me a money bullet mould and a handful of 16-1 alloy..

Other than it shoots about 20 MOA flatter than a Paul Jones Creedmoor from the 1K-line. "Magic" implies that a phenomena is unexplainable. Heck, the Money Bullet performance has been explained over, and over, and over again, you not listening??? Here's a hint: nose design and grease-groove design. I'm not the only one that's shown that to be; that is, the Money Bullet slips through the air with greatest of ease. Your shooting buddy can probably support my assertion, no? IIRC his GG'less bullets, of my design (I know that herts, megaherts, no???) shot 25 MOA flatter than his 540 PJ Creedmoor bullet from the 1K-line. Come on now, fess up dude.
