I think the problem was that I was trying to load 75-77 gr RL22into a 300 WM and seat the bullet (180 gr AB)to the standard 3.34 inch COL. Then I purchased a StoneyPoint COL gauge and measured the length. I don't remember what it came up with but it was a lot more than 3.4. So I loaded a few to fit my chamber only to find out that they would not fit in my magazine well. Actually the tip of the bullet caught on the front of the receiver when trying to eject the full round. So I measured the length that my mag well would accept and found that to be 3.495. Now I need to load a few rounds at 3.495 and see how that works.

I think this might work OK for 180s. I would like to load 200 Nosler Partitions also. Since they are somewhat shorter that the ABs, maybe it will be OK.

After using a Stoney Point gauge, I don't see how a reloader gets by without one.
