ahhh! une pas pire sur le site de Krieger: a propos du ''5R rifling''
-l'information: ''Thanks to approval by Boots Obermeyer, Krieger Barrels, Inc. is now offering the true Obermeyer 5-R
rifling pattern as an option on limited calibers with our barrels.''
Ok, on a hate de comprendre a quoi sa sert?
-La suite: ''The Obermeyer 5-R
style rifling is simply a different style of rifling that has a 'ramped' or angled transition from the groove to the land and back down from the land to the next groove. Our conventional 4 groove rifling has a nearly straight side to the land
Ok.... on est pas trop avancé, mais on espere toujours....
-La conclusion (yesssss on va enfin savoir!): ''We have honestly seen no significant diferences between the two styles of rifling when comparing our barrels. ......We do not expect any accuracy, barrel life, velocity, or other performance differences from our 5-R
rifling than we do from our conventional 4 groove barrels.''
Finalement, a part prendre 30$ de plus, le 5R riffling sa sert a rien , si j'ai bien lu....
