sabotloader, both of my renegades are between 543 and 544.
Pioneer2, In my opinion the best twist for conicals is around 1-32 my 1-38 does a good job with them also the 1-48 will do a decent job with both PRB and conical it will even shoot a decent group with the shorter bullets and sabots but if you go past what the individual gun does to the rule of thumb for heavy hunting loads as I see it the 1-70 for PRB the 1-32 -to 1-38 for conicals and short bullets in sabots and the 1-28 for heavier bullet and conicals especally with 70 to 90 gr loads that dont kick you into next week.
