I'm working on a new bullet, Hornady 150gr SST Interlock for .270wsm
wanting to learn more about the COAL affect, this winter,
So, where do I start for the OAL with these stats in mind?
my rifle has a long throat, much longer than the Magazine so seating to the lands is a non issue,
The Max magazine length is 2.93,
the Book has a COAL of 2.785, which buries the bullet way deep, (.675 inside the neck)
total bullet length is 1.367
If I just go Max Mag length I have .53 of the bullet inside the case neck.
So where do you guys start with something like this, at the book recommended length, or somewhere in between?
Only reason I am not necessarily going Max Mag length is that I see the tips of other bullets slightly deformed by the recoil against the front of the Magazine when firing with full mag while hunting, so I am interested in going deeper, since I'm so far from the lands anyway and having no problems achieving good accuracy with "Jump to the lands," on many other bullets
Advice ? Thanks
These Interlocks do have a plastic (or polymer or something) tip so maybe they'll ride out at max mag fine?
