While this may possibly ruffle a few feathers, it’s my personal, honest opinion.
I know that things like “pride of ownership” “bling factor“ and the “if it’s expensive, it must be better” effect, make some people find their shooting more enjoyable... So for them... Yes... A more expensive scope might be worth getting. And If you shoot in competition and you’ve spent lots of time perfecting your “soft hold” and you’ve already spent a lot of money having your gun tuned. A comparatively tiny increase in accuracy is well worth the extra cost.
On a springer, With a solidly clamped one piece mount, there’s little creep and consistency will be slightly improved, but all the shock goes through the scope and that’s not so good for it’s longevity. With two piece mounts, creep is more likely, and will reduce the shock by a fraction. But having the mount possibly moving around isn’t brilliant for consistency .
I’m quite happy to put my Sidewinder on any PCP with no worries. But on my TX200 I’ve got a £75 Mountmaster 3-9x50 AO on a one piece Sports Match mount, Because I don’t shoot it in competition, and at 40 yards, my groups are only a couple of millimetres larger than the ones I shot with my Sidewinder, while I was waiting for the Mountmaster to arrive by post.
I might have to replace the Mountmaster once, or twice over time if the gun shakes it to bits, and I might have to zero it more often, but I’m not going to risk losing a £400+ scope, when I don’t shoot in competition, and never shoot pests, or game beyond ethical 12FtLb range.
Like I said... It’s only my opinion... Others will differ... And even some who agree, will still use expensive scopes, because of peer pressure.
Where be your gibes now? Your songs? Your gambols? Miserable bugger!
