I have only shot two 5R barreled rifles, and can't say they are easier to clean or shoot any better. The first rifle was a Remington target model 308 with a heavy 20" barrel. On the barrel it said the twist was 11-1/4", or something like that. It shot 168 grain Sierras like crazy, but the throat was so long shorter bullets didn't shoot well. The other rifle is a Savage Model 110 Hunter in 280 Ackley, It's a good shooter, but doesn't clean any easier than my other button-rifled Savage rifles.
