Who has 1 and what ya shooting -257 WBy

[Smokinyotes]

I bought a Tikka T3X and took it to KS Arms and had it rebarreled to a 10 twist 26" 257 weatherby. I bought some 110 accubonds and have done up some test loads with IMR 7828 and H1000. Looking forward to trying it out when it warms up a little. Just wondering what bullet/ powder combination you guys have found to work best.

[fps plus]

Your definitely on the right Track. The 257 wby is a candidate for the X bullets

[Smokinyotes]

I was going to try some ballistic tips until i saw max velocity 3200fps.

[Kurt505]

I used to use Barnes tsx with imr7828 with excellent results.

[farmer23]

I have had the best luck with 110 gr Accubonds and 72.0 gr RL-25 or 69.0 gr of IMR 7828SSC.

[hunter0968]

115 bergers, pushed by imr 4350

[STY181]

115 nosler partitions and R22

[Alta_Redneck]

I got a 257 last year and loaded 100gr ttsx bullets. I had terrible results with that bullet this year hunting. Zero expansion, this was on a hot load and a solid hit on a big whitetail buck at roughly 300 yards. I’m going to load the 110gr accubond for next year.

[Desert Eagle]

I run 115 partitions with a max load of IMR 7828.

It will group 3/8" if i do my part.

[Timothy]

Good results with 120 partions and rl22

[Big Lou]

115gr Bergers and H1000. Mine likes the 115gr BTs as well but you stated that’s a scratch already.

[MooseRiverTrapper]

Could run a 270win with 110ttsx and 3400fps. Out performs and cheaper then the weatherby.

Or I could run a 300 Win Mag with 130s at 3700 and out do it all. Why?

Goodness sakes.

The 270 with that load is comparable the 257 and is factory chambered from tikka

I've got/had both. The 270, albeit a fine cartridge, doesn't compare to the whiz bang of the 257 bee. There is something called ballistic coefficient that will not allow the 270 to keep up the speed.

Higher BC in the 110 .277 then the 100 .25 TTSX

[Beeman3]

I shoot a 25-06 AI and it is comparable to a 257 Weatherby. It will shoot 115 Bergers at 3350 fps with H1000. For a longer range rig I would look into this combo. The 25's are fun but really lack high BC bullets. This load will hold enough velocity to expand the berger out to 800 yds @ 1791.8 fps. Problem is the light bullet is out of energy at 800 yds, only has 819.8 ft lbs left. So for over 1000 ft lbs limit shots on deer size game to 650 yds.

[whitetail Junkie]

My Mark V 257 Weatherby is most accurate with 90 grain hornadys...

Well I'll be....

As already noted in this thread (not to mention thousands of others) the Barns bullets are totally unreliable. To buy a 270 for the reason of shooting the worst bullet on the market to try and make it into a 257wby silly. Trust me I know been there and done it.

Trust me I've been piling up big critters with it.

[ROA]

That's nice.

Or you could run the 110ttsx out of the 270wby at 3600fps.

Just sayin

[Krokitt]

Personally like the 110 accubond, some fragmentation and about 65% retention , the best of both worlds , also 3650 fps.

Barnes bullets are NOT!! unreliable they just need to be used in the right application. A common misconception with the ttsx is that it was made to open up at lower velocity then the standard tsx. However it’s quite the contrary they are designed for a minimum expansion velocity of 2000fps as opposed to the 1800fps required for the tsx. This was for high velocity close range shots where petals were falling off the regular tsx. I run strictly Barnes and Berger and the deciding factor on that is muzzle velocity. Barnes bullets are also very accurate and easier to reload with then the bergers. At the end of the day a guy still has to do his due diligence and know what he’s shooting and why.

Cheaper, certainly. Outperforms...... no, similar maybe, but not out performing.

Always the same old argument about velocity, even with a clear example in this very thread that is not always the case. Next someone will say than any bullet can fail yada yada yada. Funny how for 15? years now most of the time it's an X bullet of some generation . Blinders on straight ahead....

I do like using Barnes to make tiny holes in paper.

As far as hunting goes, rapid expansion and fragments just plain kill stuff better than tiny holes.

Everyone has their preferences, I choose not to use Barnes hunting anymore. However a laser beam like the 257 bee is one of the few cartridges I think works well with them.

No blinders here. Like I said I use exclusively Berger and Barnes because that’s what works for me. I’m not biased and everyone has their own opinions and experiences on bullets and I am not closed off to that. I just do not agree with your statement of “completely unreliable”. They work great for me as well as mooserivertrapper when used how I described.

[EZM]

Best results for me are with the 110-115 gr (heavier bullets) and have tried partitions and the TTSX ......... both were tack driving accurate and stopped everything I've shot at .... on the spot.

I've shot hand loads and factory ammo. The hand loads were near max pressure and were slightly tighter (but I alos tested in ideal conditions so maybe that makes a difference as well). I'm not a marksman but sub moa is very easy to achive in this cartridge (even with factory ammo) and even out of my novice hands.
