Both rifles are accurate and have tested at 1/2" benchrest groups (5-shots) at 20 yards, many times.
As far as I know that is not super-accuracy for a springers. Top spring rifles (let's say HW97, TX200...) can do something like 1/4" in the same conditions. My RWS 34 was doing 1/2" groups at 30m (~33 yards).
And, in my experience, the hold it not always shifts the point of impact. More often it alters the size of a group.
I guess I should have explained the Optimus a bit more. The cost for this budget priced Chinese springer rifle is only $89.00 USd with a 4X scope and mount included. It's not a field target rifle to be compared to a TX200 or HW97.
When I test for group size I typically shoot 5 to 10 groups and repeat the process on several different shooting days. This way I know if a small group is typical. The Optimus has shot 1/4" for 5 shots at 20 yards but that is not typical.
I still consider 1/2" at 20 yards to be accurate for a sandbagged cheapo rifle with a cheapo scope and 53 year old eyes steering the gismo. I did not use the adjective "super" to describe the accuracy. Younger eyes, a better rest and better scope with high magnification might squeeze things down a bit more.
Your RWS/Diana 34 is a great shooter! My HW30S would only average 5/8"ctc at 30 yards and I thought that was acceptable ( .58, .70, .60, .79, .56 - ave = .65” ctc). The same rifle averaged .16"ctc at 10 metres, although the best group for the 10 groups at 10m was .09"ctc. Your RWS/Diana-34 must consistently do tiny little ragged holes at 10 metres. That rifle is a keeper for sure.
Here are some actual test results for my Optimus.
5-shot ctc groups @10 metres
JSB Exact (8.44gr) – .26, .26, .31, .20, .19, .32, .16, .18, .19, .22 = .23” ctc ave
5-shot ctc groups @20 yards
JSB Exact (8.44gr) – .44, .63, .26, .60, .57 = .50” ctc ave
JSB Exact (8.44gr) – .47, .50, .38, .62, .42, .61, .53, .49, .66, .63 = .53” ctc ave
You may have missed my point in comparing the rifles. The purpose was to show how a light-weight, budget priced, high power springer can be more sensitive than the same rifle that is set to a low power. I was not trying to prove that the $89 rifle was a match quality rifle. Sorry if I created some confusion.
