I am building a new long range elk rifle and I need some advice from the wise folks on this forum. First off, I'm 100% committed to using my Thunderbeast Ultra 7 can on this build. I shoot supressed on all my rifles and just can't go back to shooting without a can.
That constraint creates some issues when you consider I want to use 215 or 230 grain hybrids. Additionally, I am trying to keep the barrel (with the can) under 30" so the complete package isn't too unwieldy in the field. That forces me into a 23" or shorter barrel. I realize this hampers the 300's capability a bit, but I am curious what I can expect going to a shorter fast twist barrel and a slightly faster powder then say h1000. Possibly 4831, etc.....I will primarily use this for elk hunting, but I will shoot over 1000 yards on steel year round.
This is what I have in mind for the build, so please tell me what you think....by the way I have all these parts. The only thing I haven't done is cut, chamber, thread and crown the barrel.
Stiller predator action
McMillan edge gamescout stock
HS precision bottle metal with 3.7" mag box. Can run 215-230s at 3.6" COL
Bartlein 8 twist .308 barrel. Light Palma contour, currently uncut
Timney trigger
4-16x42 f1 NF ATACR
20moa rail
TB Ultra 7 can
Do you think I can get to 2850ish FPS with 215 berger hybrids and still have a supressed gun that is reasonably maneuverable in the field? I am 6'4", so I am more comfortable with slightly longer rifles, but a supressed 26" barrel is just too much of a good thing in my open opinion. Therefore, an 8 twist 22" tube seems to scratch the itch, but I have no experience with this combination. What do you all think?
Regards,
Ted
