So after having a blast at the TCRC Precision Long Range 22LR Match.
http://www.canadiangunnutz.com/forum/showthread.php?t=488108
Next one is Sept 5 by the way.
Three of my boys now want to shoot this match. Crap only got one gun.

So I picked up a Tasco 6-24x42 scope. On sale $114 taxes in, at my local gun store, with two free shooting bags. With 85 MOA of adjustment I was hoping it would have enough elevation for 300 yards. Well Crap it does not have enough elevation. So I decided to shim the base of one of our 10/22s.

Worked out great. Still have 10 MOA of elevation left.
I would have posted some targets but it was raining today with a strong wind. Boys will be out testing this week, with pics to come.

Now if we shoot in two different squads, all 4 of us will can shoot.

Here is my dope.
25y -5.5 moa
50y -4.5 moa
100y zero
200y +22 moa
300y +29 moa

I'd love to give this a whirl but but if you ran out of elevation with 85 MOA then I defiantly don't have enough with only 26 MOA. I had to get the burris -10/+10 insert just to have enough adjustment to change from 25 - 100 yards and would be lucky if I had another 10 MOA left.

Scope is a Bushnell 4200 Elite, 8-32x40AO. I love the damn thing but the lack of adjustment is a huge downside!

You could get the Burris +20/-20 inserts for $15.
That should give you enough elevation.

Come out and give it a try. I will be out this sat, you could come as my guest.

I thought about the inserts but as I'm already using the +10/-10 in order to have enough elevation for 25 - 100 yards. I'd assume I'd have to use the +20/-20 at least and perhaps the +5/-5 etc... And try to zero @ 100 using the inserts alone, which would then give me the entire 26 MOA for elevation. But even at that, your dope chart had +29 MOA for 300 yards so even with different inserts for a 100 yds zero I still may not have enough elevation to reach 300 yards.

Only other option would be to try and find a decent hold over point and see how that works. I'd also have to source some decent ammo as I doubt the Blazer will work well @ 200 & 300 yards.

Regardless, defiantly interested in giving it a try so perhaps I will PM you to make arrangements to come out Saturday ;)
 
We are finding that 20 MOA rails are often not enough on 10/22s. I suspect that the clamping mounting system introduces barrel droop on some rifles.

I'm thinking that a metal shim and some bedding compound would be a better inexpensive long term solution.
 
It appears that adjustable V-blocks are sold to fix this. They seem to be nothing more than a V-block that is tapped and threaded with a set-screw that pushes up on the barrel. I'm going to try tapping and threading the factory V-block to see if it does the same thing.
 
buy a cheap feeler gauge and tear it apart to use as shims, tougher than plastic and you can measure your shims.
 
I called up EGW and they will re-machine the base in any angle you want for an extra $20. I just ordered a 60 MOA extended rail for $83 shipped to my door.
 
komb, that's pretty neat that they will do any angle one asks for.

I've got a 10/22 with a 20" heavy barrel and a Hogue stock. To prevent barrel droop, I cut a piece of sticky-backed foam and stuck it to the stock at the end of the barrel channel. The idea is to provide some support to the barrel so it won't droop. A neat idea that I've read in another thread (but not had the courage to attempt myself) is to soft-bed the barrel in the stock using silicone sealant. After having used Silicone II sealant from CT in my kitchen, I can attest that it's pretty durable stuff!

For this rifle, I have a Sightron scope with 60 MOA adjustment. I used the burris zee rings with inserts to get the scope to the bottom 1/4 of adjustment for the 50 yd zero. However, I still need to use mildots for 300 yds. If you've got mildots, and you're comfortable shooting at the same magnification (for me it's the max mag of 14), then mildots help. For example, 4 mildots equals 14.4 MOA. This setup worked fine for the one match I had the chance to attend.

I have also bought a 15 MOA rail from rimfire sports, which I will install in the future. I don't need the 15 MOA because I have the flexibility of the zee rings, but I figured since I wanted a new base I might as well get a little angle built in.
 
Yeah, I was doing the mildot thing last match... but, I'd prefer to do it right. Unfortunately, the 30mm Zee rings don't give me enough elevation even with my 20 MOA base.

I've got a ring of electrical tape wrapped around the barrel to see how well a bit of pressure works. My action is already bedded in my stock, so it won't move. It's been working well. I'm going to test it a bit more once I get the new rail, and if it works well, I'll epoxy bed a pressure pad into the barrel channel.
 
Got the 60 MOA EGW base this morning and mounted it. The machining on the bottom was nice and smooth. The aluminum is bare there now, but its totally hidden. It took the 25 yard zero down two full turns (12.0 mil), with more than a full turn to spare and an extra turn beyond the 300 yard requirement.

To my surprise, my Aimpoint Comp M2 still zeros on it at 25 yards (but has to be cranked all the way down).

All of my scopes are FFP, so the mildots are always true at every magnification. And since my turrets (and dope) are in mils, no conversion is needed. I don't have to do that for deliberate shooting anymore, but still use hold-overs and hold-offs for wind and minor adjustments, and on stuff that's moving.

I can definitely see the appeal in mil turrets, as having to think in both MOA and mildots is like trying to do science with imperial units! I would also prefer FFP. I know there is the downside of thick crosshairs at high magnification, but having the same hold-over at any magnification sounds great. This is important because scopes of higher magnification reportedly need to be dialed back in mirage. Hopefully I won't run into this with my scope since the maximum magnification is 14x.

Anyway, that's the nature of the shooting sports. We try to do the best with the budget we have! I see some nice scopes in my future 5-10 years down the line. :D I do hope more manufacturers make FFP mil scopes.
 
On my Falcon, the crosshairs are 0.06 mil thick, which is only going to cover 0.540" at 300 yards. More than fine enough for this application...

On my Premier, its 0.025 mil thick, that's only going to cover 0.225" at 300 yards.
