Twist rate on .257 barrels

Twist rate on .257 barrels
« on: March 29, 2018, 05:37:36 AM »
Good day Ladies and Gentlemen,
Does anyone have a definite date of when Weatherby changed the twist in the .257 Barrels?  I have been looking but seemed to keep coming up with descrepancies around when this took place.  I have seen dates as early as 62 then more definitive around 64 but some sources saying as late as 72, when the move to Japan happened ? Any help would be greatly appreciated. Thank you .

Regards,
Gary

I don't know the date but I bought a Japan made .257 in 1976 and it was 1 in 10 twist.

If you're trying to figure out the twist in a rifle you own, use a tight fitting patch on a jag and Mark your cleaning rod so you can track distance over a single rotation of the rod.

Thank you dubyam.  No sir I am looking at a couple of German 257's and I have owned a pre-bolt safety with four digit serial number in the past that was made in 59 or 60 and it had a 1-12 twist.  I could never get that gun to shoot anything but 75gr H.P's and I just don't want another one of those.  I have question the gentlemen about the guns but he didn't know twist on them and i was just curious if I might could figure it out by serial number and year made.

No firm date, but I have one withe a SN of 34898 from W. Germany that is a 1 in 12. Bullet length seems to be the issue with the 1 in 12 not necessarily the weight.

I am currently shooting the 80gr TTSX well, it also likes the 100gr Hornaday Spire point.  I have tried the heavier grained bullets from Barnes and talked with Weatherby at one point.  I tried a 120 something (can't exactly remember what it was) grain Barnes at one point that would not stabilize because of the twist rate, they told me it wasnt the weight but the length that is the problem.  Weatherby used to have a round nose cartridge they sold, which was for this very reason.  It gave the 1/12 rifles a heavy bullet option, but I dont think they sell it anymore.

It is the 117 grain round nose.It's BC is not good,but it packs a punch.Find a box of Weatherby loads on gunbroker and try them.They are still sold sometimes.They are in the old yellow and black animal picture boxes.Usually you can get them for around 35-40 bucks a box.
Sorry... Yesterday was the last and final day for any and all complaints whatsoever.
