[QUOTE="sdeering, post: 377296, member: 10986"] A few points some already mentioned. Stay out of dougnut. Should have one bullet diameter in case- .308 bullet should be seated in .308 or more. What you can do is load a round that just fits the mag- make sure you have more than .308 depth in case. Take you calipers and set them to .307 slide the calipers down the ogive of bullet till they touch bullet, this is where your lands will start to contact the bullet. You can turn the bullet lightly, making a very light scratch mark on it. now measure from the end of you brass to the scrach. This will be your freebore distance. This will get you close to what you need. You can shorten the dimension some to alow for throat erosion. This may not give you the (optimum round) but will give you mag fit and touching the lands.
