[QUOTE="MMarshall, post: 571285, member: 38541"] I've used the system with repeatable results in 19 rifles to date. However, with my 300 RUM a few days ago while measuring a 180gr E-Tip I ran into a very frustrating condition. Due to the shape of the bullet and where it contacted the lands or throat I was getting huge variables. It was the first time I've ran into this problem. I tried other bullets to make sure I wasn't doing something wrong. Only the E-Tip would give inconsistent readings when compared to Accubonds, Partitions and VLD's. I could feel the bullet touching but continuing a little deeper with every attempt. That resulted in a different reading with every check. Other bullet shapes would come to a repeatable stop every time. On a bright note, I did develop a great shooting load with 98gr of Retumbo, Nosler brass and CCI 250's shooting 3340fps and putting three shots inside of a 1/2" at 100 yards. I went with max magazine length minus .015 and gave up on the OAL tool with this bullet design. I'm around .200 off the lands give or take .025 [/QUOTE]
