What do you think about the RPR22? [...] What about a tricked out 10-22?
Between the two, I'd bet on the RPRR over the 10/22. The Savage Mark II I shoot is about on par with the RPRR for performance and handling, and it easily outperforms my wife and I's 10/22's.
Equally, I've been chatting with a few other match directors lately which host monthly NRL22 and PRS Rimfire matches about how to design matches to bring in "gunowners who aren't competitive shooters," as I'm exploring range layout/design options to start hosting matches next season on one or two of my properties, as well as discussing how we can get more and more participation out of all of our matches. How to accommodate the common-man's 10/22 comes up in every conversation - because so many "gun owners who aren't competitive shooters" already own 10/22's (same with 3-9x SFP scopes). There is an unwavering consensus that matches would have to be redesigned to accommodate 10/22's, because the performance gap is too large. One of those match directors runs the largest NRL22 club in the country, and one of the ranges he uses also hosts centerfire PRS matches - and they even host specialized matches designed for AR-10/15's because they see the gap in performance on the centerfire side, AND recognize there are SO many "gunowners which aren't competitive shooters" which already own AR's, so they tap into that market. They do intentionally include a few "semi-auto friendly" stages in their extra stages beyond the monthly standard NRL22 matches, but it's only ~2 stages out of 10 where the playing field is kinda leveled. Maybe another way of explaining it - all of those guys which host these matches point to the fact: if we design matches so 10/22's can be successful, then either 1) dudes with Anschutz, RimX, or Vudoo rifles will clean the match, or 2) the game becomes a speed/action event, and totally diverges from what is Precision Rifle Competition. It's getting tougher and tougher for inexpensive bolt action 22's to keep up - Production Class is one option, but it excludes "tricked out 10/22's".
If you OWN a 10/22, come out and challenge your skills and your rifle, but calibrate that there will be shooters at that match with years of more experience and with $5000-10,000 purpose built rigs. If you're buying new, don't even consider a 10/22, let alone buying and customizing a 10/22 (at added cost).
One other consideration for using a 10/22 for PRS/NRL22 games - you have to be relatively selective with your ammo choices, or maybe better stated, you are more limited in ammo options - as many of the match quality 22 ammo is pretty heavily waxed, and will gum up a 10/22 within a few stages.
