I'm finally getting my 416 Taylor project rolling. I would like to know what twist rate the other Taylor shooters are using on their rifles. Thanks.

A lot of guys use 1-14". I went with 1-12" based on some discussions here that indicated it might stabilize solids better for penetration on game. If I remember correctly, it isn't supposed to make a difference with expanding bullets.

If I am not mistaken the original one had 1-16" twist barrel.

I really don't think anyone would notice much practical difference between the 12 and 14" twist.

Mine gives good velocity and accuracy with 300 to 400 grain bullets using a 1 in 14" twist stainless Shilen barrel. I wanted to get an easy 2400 fps with 400 grainers, so chose 26" length. It worked.

The 1 in 12" twist is the only other twist I would consider, and might rather have it myself. It might give better penetration with solids, but the 416 never was weak on this.

The 14" twist is the standard for all the 416's IIRC.

I checked the A-Square reloading manual because it has more "interesting" data than the others. I also think it is A-Square's best product.

Here is what I found:

.416 Taylor 10"
.416 Rem 14"
.416 Hoffman 10"
.416 Rigby 16.5"
.416 Weatherby 14"

Ron,
Care to post your load info, There isn't a lot of it around and it would seem yours is about optimal.
Myself, I used a 1-14" twist rate, but intended to use mostly 350gr. bullets anyway. I haven't heard any complaints about 1-14" with any weights so far.

My Taylor is at the smith. I chose a Shilen match grade barrel 1 in 14 twist. This is the twist my gunsmith recommended. The finished barrel will be 26", my goal is to reach the 2400 fps with 400 gr bullets.

Ron how is the Quality Cartridge Brass working out?

HunterJim,
Art Alphin used 10" twist barrels on just about everything, one of his trademarks for A-Square rifles: fast twist, better penetration?

NBHunter,
I have neglected the 350 grainers in the Taylor so far, but would like to try one day.

My loads:
300 grain Barnes X-Bullet
*************************
Primer: F215
Cartridge case: Remington 458WinMag brass necked down (246.0 grain case weight average) interchangeable with Quality Cartridge 416 Taylor brass (244.5 grain ave.)
Powder: IMR 3031 @ 72.0 grains
26" Shilen velocity = 2671.5 fps

400 grain Hornady RNSP
**********************
Primer and case same as above, same 26" Shilen barrel.
Powder: RL15 @ 75.0 grains
Vel. = 2408.3 fps

Bigdog,
The Quality Cartridge Brass is good stuff. works fine, and has the proper headstamp.

I am still waiting on the first run of 470 Mbogo brass from QC.

Canuck,
I don't always recall correctly off the top of my head. 1 in 16" may well have been the original Rigby twist. I just recall that the 14" twist seems to be the most widely accepted nowadays for the .416 bores.

Another thought: The Winchester 458WinMag brass is lighter/has greater internal capacity. The above charges will give lower pressure and velocity in them. Or, one might use more powder and get greater velocity at the same pressures, but marginally so.

For the .416 the same arguments are valid as for the .458:
For a stable flight in air 1:14 or 1:16 gives high stablity factors even for the heavier bullets.
But for a stable travel in the target, the minimum is 1:14. For a DG rifle and shots at close distances 1:12 or even 1:10 is better.
See the experiments with the SuperPenetrator .
1:16 rifles (some Weatherby�s) got more bad reputation than necessary because of their bad stability and therefore penetration in game.
