107 vs 110SMK vs 115 DTAC RBT base to Ogive

[FatBoy]

Can someone take a measurement from a couple 107SMKs and a couple 110SMK, base to ogive for me please? If you have any of the new 115RBTs and could post that, it would save me some time and cash.

I appreciate the help,


Chris

All are approximate
107 .520”
110 .540”
115 .575”

Now measured with my comparator it which measures the ojive at .233” to base things change dramatically.
Including the length of the camparator.

107 2.047”
110 2.045”
115 2.145”

The 115RBT really fills in the throat fast.

Have all three, I'll see what I come up with, but it depends on what you use for a comparator, you'll get different measurements

I always have mine throated long for the 115's. Tim Claunch will chime in.

Thanks, Guys. I throated a barrel .025" deeper than I expected and am a little concerned with errosion. I always jump my SMKs, so I don't think its going to hurt much (if at all) for the shooting.

I consider the Norma Dasher a touch on the small side for the 115s, but if I can get them to 2900 (30" 7.5 twist) and they hold the same accuracy as the 107s and 105s do, these may be the ticket to just running with it until it's time to pull the tube.
