Welcome cgdavid.
I don’t have a benchrest background, but it is my preferred shooting style. I wound up with a Crown 600mm .30 cal, and my range has 30 and 75 yard backstops.
My first 75y group was .47 c to c x 9 shots 1 flyer.
That gun is crazy accurate and because I’m plinking and not punching paper, it’s not real challenging at 75y to hit the smallest targets. It is also overpowered for the range, damaging the steel store bought targets. So I wound up shooting a high end springer that fills the bill.
I haven’t grouped it at 75y yet, because it hasn’t yet been consistently accurate. That is my challenge with it. 75 yards is long range for this guy and I throw shots right and left because of “can’t”. I can’t see a level, and the plum-bob at the backstop is only reliable for close proximity targets, so I bought a “Send It” level, and a pack of bench rest targets to try out. The targets are 50y targets shooting at 75y though. It’s kind of nice not to have to charge the springer up just cock, load and shoot. The Crown gets three mags a charge, and they go quick.
View attachment 498400 I guess where I’m going here is are you considering air gun benchrest competition, because that rifle may be overkill for a backyard range.
I look forward to reading your posts.
All the best!
