I use the Sinclair OAL gage, but the type of tool is not as important as safe accurate loads. I develop new loads with the bullet seated as close to the lands as the particular rifle's recorded history has indicates. If I've not been successful at .005 and always end up at .010 to .015 with my favorite quarter bore then I start at .010. No use to waste time at .005.Originally posted by Injunear:
Well, I've got the OAL gauge. What's the best distance to seat off the lands for the best accuracy?
