3B at 24" That ill get you there with the right stock/Chassis and optic and still have enough meat for a 5/8 thread
Thanks. I’m also willing to incur additional costs for some serious fluting if that is more of a rigidity and heat buffer advantage. Something like the chain length or hexagon pattern from LRI.
Been a while since I’ve loaded for 6.5cm. Looks like 24 or even 22 will work with the 147s and R26 (which I already have a ton of).
I’ve been trying to ask questions on their Facebook page but the admins won’t approve the posts. There are other obviously new potential shooters that are able to ask questions, so not sure what’s up with that. My FB is pretty sparse, may not like that.
Fluting on a 3B will save a miniscule amount of weight. Fluting and rigidity is a function of weight when comparing two barrels of the same length.
One of those forum tales that has never gone away...
I was thinking a more heavier starting profile fluted down to about the weight of a 3b
Right, yeah the argument is that all things being equal the fluted barrel will have less deflection that a non fluted barrel of equal weight... Gun smiths as well as barrel makers are split on this subject.
The rabbit hole is strong with this one. Some people lean on the I Beam effect and corrugated geometry of the "correct fluting".
Geometry (Spiral, straight (would make the most sense to me), 3 flutes vs 6, Hex pattern...ect and then depths and radius on all of the above, how much stock you end up with between your flutes and the bore wall... the list of variables goes on and on.
Others on the against school lean on mechanical elastic modulus of material removal. I think this is one of those no right approach deals where there is no straight answer.
Going back to the actual question, if the end goal is to have a NRL hunter legal gun under 12# i dont think fluting will make that much of a difference. Ive shot a handful of these and most guys are running 3Bs and light/medium palmas when not running Carbon wrapped.
22"-24" will get you over the 380K points for power factor with a 140 in 6.5 or 135 in 25. and almost no one runs shorter than 22" on the short cartridges
I just got a 24" Sendero contour Hawkhill barrel spun up in 6.5 Creed for NRL Hunter. On a Rem 700 (actually my hunting rifle, haha) in a MDT HNT26 with folder, topped with a Vortex Razor LHT 4.5-22 in a Spuhr hunting unimount and with a lightweight double-pull Ckyepod it's just under 12lbs. If I throw on my Razor Gen 3 6-36 in a MDT One Piece mount and swap the lightweight double-pull for a triple pull, it's just under 16lbs.
