Actually 75 yards would be my max distance so I will likely set my MOA with a centered scope to maybe 40-45 yards? Actually a 55 yard scope angle would be pretty well centered for a range adjustment from 30 to 75.

Using JSB .20cal, 13.73gr, 728fps.Lets start from scratch. How many inches drop do you have at 30 yards when optically centered. What velocity and what pellet? I might have mis understood the whole situation. I'm sorry
I need the measurement in inches between POA I'm assuming the bullseye and the POI. I can't tell by looking at the target. Pellet and velocity. Approximate scope height or what rings were used.
You're right. Rings could be at fault in some cases. Theres ways to check that. On a dovetail gun it's pretty easily checked. Just slide the rings together and check for a difference in height or offset. A difference of 0.023" would be glaringly obvious.How do we know it’s always the gun and never the scope rings? Does anyone know what the tolerances are on scope rings? For scope rings placed 4” apart a height difference of .0233 inches will result in a 20 moa shift. This could be a result of loose tolerances like +\- .010 and +\- 1/2 degree. The rings may be twisted slightly or the hole could have a little angle on it and the height may be off on one ring. The odds are that if it was a ring problem it would come from “tolerance stacking”. Not one dimension way off but maybe all the dimensions off a little which adds up.
looks like shooting paradise !I'm trying to do math to figure out how much angle you need to attain your zero. For that I'll need you to answer the questions I posted before. Also what is your scopes elevation range? 30mm tube? I can figure this out but I need this information to help. GI/GO. Last night I was shooting center of a 10" plate at 500 yards with new box stock rifle, a simple Nikon scope and Walmart ammo. I got this covered if you work with me.

Thanks I still need the distance between the Point of aim which I'm assuming was the bullseye and the point of impact on the 30 yard target you posted earlier.
Sorry my phone died all the info should be up dated on my last post. It was 5.25 inches C to C on that target, at 30 yards.Thanks I still need the distance between the Point of aim which I'm assuming was the bullseye and the point of impact on the 30 yard target you posted earlier.
10 yards huh? I've been centering at 18 yards. I guess 10 yards will give you a little more elevation adjustment and more elevation spring tension. See that's why I follow these posts, to learn from the experts.A bent barrel isn’t ruined at all. The bend required to fix it isnt noticeable to the eye. My 177 97k has shot dimes at 50 yards on a good day and quarters regularly. Ive adjusted nearly all my Weihrauchs to optical center at 10 yards and they all shoot very well. Bending a barrel to optical center at 10 yards will zero again at 25 or 30 yards. Holdover reticles are used past that.
Adjustable rings are too much of a PITA for me. Most adjustable rings don't compensate for windage and IMO look like an ugly erector set on a rifle. I prefer a more elegant solution.
Almost all of these guns have had their barrel corrected. Can you tell which ones? I'll tell you the 97 has and it's a real shooter.
Area 419 is a top shelf company that makes canted 11mm pic rails for cz and Anshutz PB rifles. Perhaps one of those and Burris signature rings will fix the problem without touching the barrel. It'll cost you and it still won't look as clean as two Sportmatch rings but they are serious quality parts with a strong followingin the powder burning world.
Please dont imply that my advise to bend the barrel is dangerous to the function of the rifle. You do things your way. I'll do them my way. I've straightened out plenty of guns for a few people here without a complaint. They wouldn't continue to trust me with their rifles if I didn't know what I was doing.

You're welcome. A 75 yard zero isn't really practical for a 700 fps rifle. The trajectory falls off really quickly out there. It's naturally going to take a lot of adjustment. I've never tried zeroing any of my Weihrauchs past 50 yards. Most of my guns are 700 fps or better and the 50 yard zero takes a lot of my adjustment. I don't like running the guns that close to maxed out. That's why I usually zero at 25 or 30 yards. You're absolutely right not to like running on the ends of adjustment. Springers are tough on scopes and running them close to maxed out is probably what kills most springer scopes.Thanks for the effort!
I hope there was some satisfaction in that nice piece of work..
I am only plinking at the moment.
I have two back stops in the yard, one at 30 and 75 yards. I shoot some spinners, hanging med bottles, bottle caps, shot shell hulls, wire nuts, empty C02 carts. Etc.
The plan is to be able to quickly dial those distances without being close to the scope adjusment ends.
The situation with the current set up, zeroed at 75 yards, is that I'm using the last click of up..
I'm not to fond of that idea with a springer pounding on it.
Thanks Harold
I try to adjust to a ten yard optical center. Some guns can't quite make it without the bend becoming noticeable. If I can get the barrel level I'm still ahead of the game. Side to side drift is even a bigger PITA10 yards huh? I've been centering at 18 yards. I guess 10 yards will give you a little more elevation adjustment and more elevation spring tension.

I have been shooting the HW 30 out there at 75 yards and hitting Crazy Eights, but I use the bottom marker on the crosshair at a little over 4X. With the scope zeroed dead on at 30.You're welcome.

I love shooting my little 177 Hw30s long distance. I love hitting beer cans at 100 with my scoped 30. My peep sighted 30 is limited to about 50 yards due to too much post blocking the target. With 7-8 grain pellets, wind is your greatest enemy. Cant errors can be minimized with practicing good technique. Also a trick to minimize cant is to level the target hanger and to can use that to level the gun.I have been shooting the HW 30 out there at 75 yards and hitting Crazy Eights, but I use the bottom marker on the crosshair at a little over 4X.

The greatest challenge is cant, followed by wind. Lol
