Went to the range today with my huntin buddy, his REM 30-06 and my .308. We were there to test AA4064 and was an absolute success. Neither one of us is a genius when it comes to reloading metallic cartridges we just follow published load data and look for pressure signs. The data he had for the 06 stated a COAL of 3.340 with a 150gr speer hot core with a length of 1.049. As close as I can tell there's only about .120 of bullet in the neck of the cartridge! Is this the norm? We both shot excellent groups and no feed issues for him at all. Any opinions on seating depth greatly appreciated.

My old Speer Manual reads 3.130 - 3.25 depending on projectile. Manual #13 didn’t list a hot core. Each bullet has a different COL. How far off the lands is the bullet?  |

We were going to go through his notes but it started rainin like hell. He did however show me the data and I believe he has the latest Speer manual. For myself I figured the bullet should be deeper in the neck? There is no canelure groove on the HOT CORES and all my manuals put me at or near the groove but I'm limited to mag length in my Saure 308. He did shoot a .320 with 51.5grs of AA4064, not to shabby!

Normally I test loads close to what manufacturer recommends for that bullet. If that isn’t working I find where the bullet is on the lands then I work certain distances from the lands. I’m betting if your friend loads a dummy round then chambers that round it will come out a different length then when it went in.

UPDATE! After further investigation my buddy told me what he was up to. He told me that he wanted to try .020 off the lands but did not want to go passed max COAL witch is 3.340 per the SPEER manual. I told him I did'nt think that a SPEER 150gr HOT CORE was the bullet of choice for that kind of experiment! I told him this stuff is all about the details and he agreed only after reminding how well the set up worked. Some folks ya just cant take any where!
