I picked up some 55 grain Nosler SHOTS bullets for the 243's. These are only 0.595" long. Don't have a chance to get to the range yet. Thought I would try and get some others' experiences with them. My concern is the free bore. With 1 caliber neck retention the free bore on the 4 rifles is 0.578", 0.295", 0.292" & 0.351". Pushing the bullet out some wouldn't have any significant affect on that kind of free bore. What has your experience been with extended (won't say excessive) free bore with these tiny pills? Thanks.
