Anyone interested in posting loads up for their 416T's?
You bet, max load in my BRNO action 416 Taylor:
Necked down WW 458 WM brass [heresy] lol
400gr Hornady or partition
77.5gr CFE-223
Fed-215 or CCI-250
3.320" COL
Vel 2407 fps
Start at 70gr and work up with a chronograph please.
That would be nicely fast for a 24" barrel.
Noted, for future reference.
My 26" barrel might add 50 fps to that.
With Shilen No. 5 Sporter, 1:14" twist, Ruger Mk II in factory Tupperware, rifle weighs 8# 2 oz as here:
My old .416 Taylor (circa 1999) liked 75.0 grains of Reloder-15
with the 400-gr Hornady RNSN of yore.
R-P .458 WM brass necked down, forgive me,
F-215 primer, 3.320" COL, crimped in factory cannelure,
80*F
26" barrel: 2417 fps mean for 5-yard chrono
Nowadays I would substitute Varget for the RL-15 and work up a grain or two higher.
Or use CFE-223 like gunner500 says.
The .416 Taylor started off as the .416/.450 Watts Short in the 1950s, according to James Watts.
He gave some dummy cartridges to Jack O'Connor who showed them to Robert Chatfield-Taylor.
Then about 1973 Bob had a Winchester M70 so chambered, the first ".416 Taylor."
He did 2400 fps with 400-grainers in a 22" barrel using IMR-3031.
About 1974, Sturm Ruger made up an M77 .416 Taylor with 24" barrel and loaned it to Ken Waters.
Ken claimed 2447 fps with 400-grainer and IMR-4320, from the 24" barrel.
Bob Hagel also independently developed a .416/.338 Winchester Magnum Wildcat,
though he also used necked-down .458 WinMag brass for that,
about same time as Taylor.
A different chamber reamer and reloading dies exist for that one, close to the .416 Taylor, but no cigar.
