Signature Zees and tube similarities

Hello, I'm a 2nd year rookie BR shooter. I couldn't get this answered over at Rimfire Central:

Well, it's going to rain here all week, so I can't answer this stupid question for myself till next week. I currently have a BSA sweet 22 6-18 all zeroed in and mounted in the Zees. I'm upgrading to a T-36 and I'm wondering if the tube will just 'drop in' to the pre-set rings and be close to the bull.

I guess my real question is whether there is enough similarity between tube alignment between manufacturers? Will the new reticle be near the bull OR will I have to start over with the zee shims from zero-zero.

I know, I know - dumb question. Well - it is raining!!! sigh . . . . .

P.S. The BSA windage and elevation were centered while I went through the Zee shimming process. Only the final zeroing was accomplished with the turrents. This scope had to be shimmed 6-1/2" (@25 yds) to 10:00 to move POI to POA. That's 26" @ 100 yds!!

For an idea of where I am in my rookiedom, see this post from RFC:

I'm currently in the process of putting a $400 (T-36) scope on a $200 rifle (Marlin 925). I'm in the early phase of getting serious about benchrest shooting.

Here are the steps I've been through; I shoot at a good state run range with SOLID covered benches. Built a pvc target stand and bought a box of USBR green monster targets. Bought a good Caldwell Rock front rest and a leather Protektor rear bag. Shooting a $50 BSA 'sweet 22' 6-18x40AO scope. Tested all ammos and settled on Wolf MT for this gun. Added a shim between front of forearm and barrel. I had a pretty good first year and decided to test the accuracy limits of this gun. I had a single wind flag that first year.

Year two; I bought two more wind flags and installed a Rifle Basix trigger. I use a bubble level to ensure the target and Rock are level. Shooting carefully at 25 yards, I'm starting to get the idea of wind flag shooting. Without the flags I never really knew what was happening. After agonizing through the decision, I've decided that this inexpensive gun is a good enough shooter to justify the $400 scope. It'll never be a 40X BUT it will shoot. The Weaver will now put the ball in my court - in other words - it will all be up to my performance.

Where I go from here - who knows? I'll post scores (btw, buy a scoring plug) here at RFC and I'll choose a class where the 36x is allowed. If I decide to get out of it, I can always get the $400 back by selling it online.

I think that by equipping as I have, I can have some fun, learn through experience and enjoy what will probably be a great challenge. btw - I've always suspected that you could get a cheap gun to shoot well if you got serious enough. We'll see . . . .

P.S. Buy the wind flags or save the scope cash.
 
My bet is that you will have to fiddle the inserts again. It's likely not the tube alignment that will cause any differences. It's more likely to be the build of the internals.

But, hey, that's what inserts are for.

Put scope on rest and shoot with your BSA mounted till you hit point of aim. Carefully remove scope without moving the rifle too much and mount Weaver scope using zero degree inserts. This should put you right on target at least on paper.

Sounds like your afraid to click the scope but don't be skeered. A trick is to fire a shot at the bullseye then aim the rifle back at the bullzeye and then move the scope knobs till the crosshairs are aiming at your bullet hole. Re-aim rifle at the bull and the next shot will hit your aimpoint. To not get mixed up doing this backwards in the heat of battle I call this "clicking to the hole" (vs. not clicking to the bull) and it works great if your not good with math like me doing mills and minutes quickly and it allows you to get sighted in iwith just a couple shots total as long as you can see your first impact..

As far as wind flags your really wasting ammo and not learning anything shooting rimfire without them and even a couple pieces of surveyors ribbon tied on a stick will teach volumes and show you wind you never knew you had and explain why shots are going out when you thought it was calm. Shooting what you thought was a calm can be the most dangerous shot and it's easier to shoot when you can feel a breeze and keep track of it and shoot it as calms are hard to read and prety rare.

Try it with the inserts as is. Will your scopes parallax adjustments allow them to focus down to 25 yd. with the target in sharp focus, and parallax free?
