I have a couple Ultra Varmint .243's that came with heavy 24" barrels... they did not group particularly well... about 2.5" at 100 yards with pretty regular "fliers"... so I cut the barrels to 20", threaded them back to 9/16" X 24 TPI, recrowned, and added Ross Schuler muzzle brakes... they now group consistently under 1.5" and the only fliers are an occaisional cold barrel flier, right after a barrel cleaning... I can now put 10 shots into that 1.5" group... that is a significant improvement! As a bonus, they handle and look better too!
