[QUOTE="Bart B, post: 109742, member: 5302"] The rifling angle presented to a bullet in a 22 caliber 1:8 twist barrel is the same as a 30 caliber 1:11 twist; 5.047 degrees. I don't think it's a fast twist as far as the bullets are concerned. Bore condition may be the culprit if the bullet jackets are decent and thick enough not to crack from swaging in by the lands. Clean it good with stuff that'll dissolve/remove the powder and jacket fouling. Most any of the aggressive cleaners will do; Shooters' Choice, Sweets 7.62 or an old favorite is 28% ammonia mixed 50-50 with Hoppe's No. 9 bore solvent. One good thing is standard tooth paste mixed with light machine oil; dental pumice is the finest non-abrasive cleaning stuff there is. [/QUOTE]
