Re: expensive .22 scope?
Many considerations aside, I think the option of a high end scope depends on your application.
To my narrow little mind, the words 'trainer' and 'high-end' tend to be mutually exclusive terms.
A trainer, IMHO, is supposed to be more of a generic, high usage, familier-to-the hand tool. While high end components may be something to treasure, they add little to the central task.
Kinda like lipstick on a pig. Pigs is useful, but lipstick?
I would rather have several identical cheaper generic scopes onhand, ready to be swapped out if some questions or concerns arise; and reserve something far more impeccable for a more precision rifle dedicated to a more precision application, like competion, etc.
This is my approach, and time after time, every time I thought I had a scope problem it actually turned out to be a 'me problem'.
I guess it comes down to a personal preference of mine for a simpler, more affordable modularity in a basic, heavily used implement.
Sorta like my Father's axe that he brought over with him from Sweden in the early 1900's. From time to time a handle or a head would need to be replaced, but it's still my Father's old axe and he used the heck out of it. Even when abused, it could be easily restored to a highly functional state. Actually possible he got it from his Dad. Always dependable, often imitated, seldom surpassed.
