I think this thread will get some traction. There are enough folks around here that think a bit outside the box that may well go for this "open architecture" approach.
I don't have the patience to wait for those such as Berger and others to fill a niche that needs to be filled.
Kirby Allen has also done some work with SMKs and Alum tips. He also discovered that a little wobble made little difference in accuracy.
I started my efforts in 270 cal to attempt to fill a gap there.
My thought was to come up with a way that the typical hand loader could do his own repointing if he had access to decent tips.
Corbin's tips are way too large for a 270 cal size bullet. Too much weight is lost.
Thus I came up with a tip design that worked well using brass.
Learned a ton about machining doing this. Also learned that I'm not very good at sharpening cutting tools. Too get the points just right the cutter had to be just right. Frustrating.
As I selfishly have sufficient high bc LR 277 bullets I'll switch to the 375 cal efforts in an attempt to get more weight and higher bc with more consistent terminal performance.
I'll still work with brass tips as the Corbin tips seem too easy.:roll eyes:
Here is a pic resulting from some terminal testing. These were Nosler 270 Ballistic Tips converted to 160 grains with a calculated bc of 0.658. Calculations were done by Eaglet.
The shot well enough to hit the media entrance opening @ 300 yards.
