[QUOTE="BoatTail, post: 1801876, member: 74670"] VA SILENT ARSENAL, On my freebore, I used an interpretation of a method taught to me by Dave. Using it I come up with 0.202 freebore and COAL of 3.040 for the Nosler 142 ABLR. On the Hornady 143 ELD-X, because it has a shorter boat tail, it can stick out farther from the case and still be at or below the boat tail/neck junction. The limiting factor on the ELD-X is the COAL allowed for from the Magazine. With a 3.110 magazine, if I was to hold COAL to 3.09 it gives me a freebore of 0.252 using the method given me. What was not clear to me is if I add to the calculated freebore a 0.020 for bullet jump because I'm measuring where the bullet will hit the lands (I believe). I have an email into Dave to clarify. Holding FB to 0.220 will give the 0.020 jump for the ABLRs, with the shoulder and boattail inline and a COAL of ~3.03. With the ELD-X's and that same 0.220 FB the BT will be below the bottom of the neck and hold the COAL down to ~3.05. Again if I did not have the magazine box as a limiter I believe I could have a COAL of ~3.11 for the ELD-X's. This would put the top for the BT and the bottom of the neck at their intersection. But of course I have a 3.11 magazine limit, need to add clearance for feeding and would like to have more than one bullet option. Thus the current thought of a 0.220 FB. How does my FB compare to yours? When you recommended way over 0.200 I was thinking 0.220 was good. How do my measurements compare with you are seeing for the ELD-X on the 6.5 WSM? [/QUOTE]
