[QUOTE="tim_w, post: 1460797, member: 11132"] Check with Rich to confirm this..........but I think when you setup for the 150 smk the same freebore works well enough for the elds and hybrid as well. This is where there are is another benefit to the longer neck Rich leaves on these cases but not not taken to an extreme. It allows you to setup on the 150 and yet can still get good bullet base/BT placement in the case for most of the top high BC heavier bullets. Actually out of the various new sierra TMKs only the 224 cal does not follow the same general design format. All the others get these long necks standard body and longer BT. The 224 gets a small increase in neck basically none in the BT but a much longer body bearing surface. Because of this you need much more freebore than say the 90 VLD and SMK used for ideal base placement in the neck and makes it hard to setup for both. Not a concern here. Issue is Sierra not publishing any dimensions specs for any of the new TMK other than G1 and OAL. I love Berger for how they handle and always give you detailed dimensions. Unless you had a long COAL your receiver / mag box handle and really maxed out the freebore for the 150 in that scenario like 3.1+ you could then have an issue but with the typical 2.9 sub 3.0 I think the freebore for those works out well with the SS/SST neck length. Again best to hear from Rich on this to confirm it. [/QUOTE]
