Home Forums Hunting & Shooting Long Range Hunting 257 Weatherby 80 grain TTSX

Yeah, I have had the 100 Hornadys shoot very well in two .257 Roys, 1/2 to 3/4 inch groups at 3500+. They also work on deer very well, at least from 200 yards out, which is as close as I've seen them used.

I had a custom 257 Weatherby with zero freebore with a 26" three groove pac nor super match barrel on it.

I shot a load of AA3100 with the 85g NOsler combined technology bullet at 4130 fps that just folded up deer, buddy and I never had a deer run off or lost one.

The 85g Nosler CT bullet is one tough son of a gun

Ruger270man, in the factory chamber, the 100g Hornady Flat base with 71.5-72.5g of Alliant Reloader 22 with a Fed mag primer is lethal medicine on white tails.

Shot an honest 1/2" group with the factory wby 80gr ttsx saturday with a standard vanguard 24". The gun has had the trigger and crown done but is otherwise out of the box (not sub moa model). Barrel seems to have a copper fouling problem, but that is more of a cleaning issue. Started with a clean bore, fowling shot, then 3 shot group. Only about 75 degrees and gave the barrel a little time between shots.

just bought the rem 700 lss in 257wtby. anyone have this gun?does it shoot as goods as the vanguards?factory loads?

You guys are getting me all excited!
I have a Krieger 26" heavy barrel in 257 Wby that is going to get fluted by Kampfeld and screwed on to an action hopefully by January or so. Too late for deer hunting this year but ought to have her up and running for next season. I have a bunch of 110 gr Accubonds so hopefully they will shoot but just looked at the factory ballistics for the 80 gr TSX. Dang! 3900 fps. Should be no hold over out to 400 yards.

THINK ABOUT THE WIND!! I would shoot 100gr Swift Sciroccos.. An unbelievable BC...

721 tomahawk:

are those legit BCs or are they exaggerated?

does any body know?

thanks

Brett, I am positive they are damn close if not exact... SU35 dotes on them for long range killin..

Good to know, I'm looking at getting a 25-06 and running them out of it.

Thanks

Looking at at a 110gr AB and a 100gr SSII that are sitting on my desk, the 110 looks to be about .1" longer (by ruler). Bearing surfaces are very similar, with nose lengths and shapes being a bit different. The SSII can't be far off from .400 BC.

Ballistic Coefficient .429

That's what they claim, but BC for the 110AB is actually lower, per Nosler. Where reality is concerned, it likely matters little, as both should have very good BC's for .257 hunting bullets. I'm gonna go shoot some more of each this afternoon.

Three words...Ultra Bore Coat

+1 on the UBC.

I recently have been trying .25-caliber 100 Tipped TSX's in several of my rifles that like standard 100-grain TSX's. So far all have shot very similarly, including a .257 Weatherby NULA Model 28 that averages about 1-1/2" with 75.0 grains of Ramshot Magnum and the little TTSX--at 200 meters (about 220 yards).

as usual you guys obviously get to shoot a lot more than me. i figured a 1/2" group was pretty good from a stock non-sub-moa rifle. Is the UBC to help the copper fouling?

Here's a 150 yard exit wound on a Pronghorn from an 80gr TTSX launched at 3700fps:

I have 2 of the blued SUB MOA's and the first one really likes 100 gr. TSX's. It will pretty much cut a ragged hole @ 100 yds. I havent even fired the second SUB MOA yet, but the target sent with that one is even better.
