BSA Sweet Scope Questions

[sornjs]

I have planned to purchase a BSA 22-619X40AO scope.
I have found a "New-In-The-Box" BSA 17618X40AO at an incredible price.

Since I don't give a hoot about the adjustment for various 22 projectile weights should I get the same performance from the 17--- as for the 22---?

Thanks for any help.

No! Each scope is calibrated for the given round. I have three of them that I use for silhouette and I like them. You can still get a great bargain some places for the old scope in the 3-9 power ($39+). The new models cost more but the adjustments are more fool proof.

As I understant it, most scopes are not callibrated for any particular round.
These scopes seem to be calibrated for 22, 17, 223 and other round choices, one caliber choice for each particualr model .
Does the callibration do anything except adjust for the various projectile weights listed on the turret drums without requireing a new zero adjustment procedure?

I have two of the older models and one of the newer models. The older models have three turret heads that you change with a small allen wrench. There is very little difference in the three. On my CZ that I use most of the time for silhouettes up to 100 yards, I set it for a zero at 50 yards and I set it at 90 yards for a zero at 75 and I set it for 107 yards for a zero at 100 yards. You can see that it is not perfect but different numbers are not that hard to remember. I am shooting standard velocity and it would work different if I were using hi velocity. The differences in scope height will be a factor.

The newer models are lighter weight and shorter and have three adjustment knobs. The new one has some improvements but the old ones are good for what they are made for. The older ones are the best buy for the money.
