Thks Dr Mike ! I appreciate the info ! and GUY your right its going to be fast ! :grin: A guy on CGN uses 76 grs - if thats true its over 4000 fps ! YIKES ! :shock:

Cheers RJ

 

[Rem Jim]

Any one loading the 80 gr Barnes TTSX in a 257 WBee - if so what are you loading behind it ? Thks

Cheers RJ

 

[Dwh7271]

RJ,
Not the 80 (sorry) but I load the Barnes 100 with RL22 (71 gr) and it is moving right along.
Right at 3350-3400.

Guy was right, that is smokin'!

 

[Rem Jim]

Thkls for the added info Dr Mike ! :grin:

Cheers RJ

 

[Guy Miner]

I saw the load info on the Barnes website for that 80 grainer a couple of years ago... Wow! :shock:

With the mono-metal construction, a guy really doesn't need to worry about using the traditional 100 gr minimum for a medium game bullet. The 80 will likely work superbly on deer sized game, and frankly it would likely do for black bear as well.

Several years ago I tried the 100 gr Barnes TSX at 3340 fps on a couple of mule deer. Dropped 'em fast and bored right on through like a carbide drill bit. One I wasn't sure if it expanded, but it was a brain shot, so I guess it really didn't matter. The other expanded for sure. Made the heart look like an open phone book, the way it was laid out. I think the 80 grainer from either a .25-06 or a .257 Wby could be fearsome... Nearly 4,000 fps from the Weatherby... Sweet!

Dr Mike could you PLEASE run me quickLoad Data for a 257 WBee with the 100 gr Swift Scirocco 11's i just picked up ? I would appreciate it ! :grin: Thks

Wow, that is blazing fast, no matter how you cut it. I actually wonder how well the Barne's petals will hold up to that sorta speed. When Guy mentions it being a drill bit, I bet he isn't far off the mark!

That 100 grain Scirocco would be fearsome I believe. I have folded those inside out but man, they still hold onto at least 70% and a good frontal area..

Also, I believe, unless Dewey has found the magic, there is a little extra speed in there as QL doesn't account for the freebore in the chamber... Either way, it's danged fast!

 

[Dwh7271]

Nope, no magic yet. Bummer.
Just what I need, my Weatherby to go faster. :lol:
Would be a hoot though.
Did notice that Dr Mike and I have differing case capacities.
I agree though. There probably is a little wiggle room in there.

 

[SJB358]

Yeah, fast is fast. Even at the projected QL numbers, I can't see the little left on the table being a bad thing. I had ALOT of fun developing a load for my little brothers Vanguard. I REALLY was thinking of making an old 7mm Rem Mag into a 257....

 

[Dwh7271]

Sounds like a cool project.
As you figured out playing, errrr, shooting one over the holidays, it is a seriously fun caliber.
MRP really makes the Accubonds hum too.

 

[Rem Jim]

Thk you Sir ! I like the IMR 7828 SSC with F215 primers in my BEE ! :grin: RJ

I do have some NORMA MRP i could try too !

 

[boomer68]

Might have to try some 80gr TTSX in mine. Has anyone run these over a chrono yet?

 

[HOGWILD338-378]

Friend of mine has run them over his and it was just over 4000 fps! Custom Vanguard with Mark V barrel basically ! He worked up to that really slow and not sure if he backed it down any as he probably has not!
