For those who wonder how a factory RPR might stack up to a custom gun (like a Surgeon Scalpel):
"Over all the 150+ groups fired, the custom rifle only had a 2% better mean radius than the 100% stock Ruger Precision Rifle! What?! If you aren’t shocked by that, consider that the custom Surgeon Scalpel rifle has a price tag that is around $5,000, compared to the $1,300 I bought the Ruger Precision for off GunBroker.com. That shows the kind of impressive performance you can now get from factory rifles! Ruger, I tip my cap to you! The hard data I collected over 760 rounds shows the RPR delivers a ton of precision for the price."
This was from results in comparing various factory 6.5CM ammo.
