I've got a 22" 30 BR barrel that I finally installed after owning it for almost 12 years.
The freebore on it is very, very short, but I don't have any idea what reamer was used. I bought the barrel used. It's a Krieger 17tw.
Ogive touch point on 125 TNT and 110 V-Max is very close to the case mouth, so I'd reckon it could be a 0 freebore.
Anyway, my question revolves around the 125 NBT because I'd like to use them for some hog hunting.
So far, I've used Benchmark and LT-30. Both shoot very well, but the velocity with the LT-30 is considerably higher.
The issue is, even using an 8" drop tube, the load is severly compressed and it causes seating depth to vary by quite a bit.
What other powder would get me back over 2800fps and have enough room for this longer projectile?
Will an extruded powder do it, or should I be looking at ball powders like AA-1680, 2200, 2230 or CFE 223?
Or, since it's a hunting load, should I just suck it up and live with the occasional bullet not touching the group the others are in?
Lastly, Barnes makes a 110gr TTSX.
Would that possibly stabilize in the 17tw? If it does, then I could forget about the Nosler and just use it.
Thoughts?
