[QUOTE="tim_w, post: 2625841, member: 11132"] The only way I have seen it work is using 5r lands which is easier on the jackets incombination with a slight ¾ gain twist 8>7.25 or 7.75>7 etc to further easy the stress on the jacket allowing it to not blow up downrange from the heat of the higher rpms. Longer barrels "seems" to worsen the effect. Not sure if it's the rpm with increased vel or the longer time/distance under the severe stress of the lands/bore engraving. [/QUOTE]
