[QUOTE="elkaholic, post: 1460833, member: 13833"] The std. Reamer for the sst runs the 147 at just over 2.8" and the bullet is into the body a ways. I did this intentionally so most bullets could be run through just about any mag. It actually works out so that the much longer smk with a more aggressive nose, will work pretty well. We didn't have the150 smk when I set it up so I don't know exactly what the coal is, but it would be moved ahead considerably and be positioned better in the neck. Doing some math, using the 2 designs, the smk should be .020-.030" into the neck at the body/boat tail jct and have a coal to the lands just over 2.9".In a round about way, the neck length does have a bearing on throat length design, provided the neck/shoulder jct is the reference point. I.e. .020" longer neck means .020" shorter freebore, all else equal. Also, the longer neck does give more lee way to move bullets around and still have adequate bearing surface grip. [/QUOTE]
