Ive got another friend getting +3500fps with 110 TSSXs (isnt that the white tipped bullet?) in a standard 2506 with 28" McGowen. I didnt beleive him till he shot it over my chrono. He's wanting to use my reamer to punch it out to AI but we havent gotten to it yet.

Running a 26" pipe... and it shouldn't shoot an equal weight bullet faster than the 7mm Rem... same brass, smaller bore... means same bullet weight should be a bit slower if pressures are equal. I like the .264... but truth be told, if it requires anything bigger than a .25-06... I'll step all the way up to the 7mm Rem.

The 110 white tipped bullet is the Nosler Accubond... I could get one of those to tickle 3500 in my .25-06AIs... but lost brass everytime I did it. Running a 110 at 3500 in a standard .25-06 is pretty impressive... don't think I'd want to be pulling the trigger though.

I will say that slooooow powders do wonders in the bigger quarterbores... Retumbo, Magnum, H1000... I'm even thinking of trying a case full of US869 and a magnum primer behind the 115s... I'm thinking if you can get enough in there you should be able to push 3300 with a 115 safely. I'd think it would work wonders in the Roy if you could pack about 75-80 grains of it in a case.

That's a misconception about these cartridges. You don't have to "fireform" AI brass. You work up an accurate load as with any other cartridge. Then shoot it as you would any other cartridge and get a formed case while doing it.

Barrel is 29" Hart, 12" twist, RL22 powder, PMC brass which is very strong. And what really makes a huge difference is the chamber. Accuracy is around 1/4" with all three Sierra 100gr bullets.
 
cz, once again not enough info. What do you plan to hunt on these out of state excursions and where are you going to hunt. I would recommend the .257 for most western hunting with proper bullets but a .257 in the deep woods of the east is a waste of money in my opinion. You already have an awesome coyote rifle in the 22-250 so I don't see the need for another. Again what and where are you going to hunt with this new rifle? dedogs
 
yeah 4010 FPs with a 100 grain pill from a .257 wby is a pile of you know what...


My 115 Bergeres are mopin' around at about 3300, but ask the Coues at 571 yards I killed... dead as a door nail

This gun is just for rockchucks......a trued long single shot Savage action w/Sharpshooters stock and trigger. It shoots flat and makes a nice whop, really demolishes a chuck. Ackleyman owns the reamer. He did a few guns with it that were shooting 100's at 3850 through a 26" barrel.

Think whatever you like. Doesn't matter.

The 257 Weatherby's closest comparison would be the 25-06 Ackley Improved. Both will be a more than you need for coyotes. Ammo for the 257 WBM can be hard to find in most areas. If you don't reload consider the 25-06 for availability of ammo.
 
Yah the 257 WBY is fast and flat, and its technically "king" of the quarterbores, but really, it has its limits. It doesn't outdo the 25-06 by enough to make a big difference IMO. If you want to shoot deer further then a 25-06 or 257 WBY will go, you need to step up in bullet diameter to either 6.5mm or 7mm where the BC on teh bullets is in the high .5's and low .6's, better then .400-.450 like with .257 cals...

Thats the chitty part about .25 cal is there BC's, plain and simple...Aint no way around that one. It falls right in the middle of 6mm and 6.5mm, dont see how they can have such good BC's and the .25 cal dont...??

I always wanted a 257 WBY, but when your 14 years old, its kinda out of reality...My 25-06 served me very very well for 10 years out to 600 yards on several whitetails and mulies. A 257 WBY wouldn't have killed them any deader or faster...Now that I"ve grown up a bit and know whats what, there is a lot better choices out there for LR hunting then any .257 cal.

264 WM is a helluva round. 10x the round the 257 WBY will ever be. Run the numbers and you'll see why, and which wins out at LR...

BTW-257 WBY for a coyote rifle is ridiculous...If you want it for a dual purpose gun antelope/deer, yah I can see that, but for strictly coyotes?? Really??

OK, What velocity are you getting with the 264 WM ?
I wanna do the math.
This is my load data from my 2506AI velocities
A .257cal 100 gr nosler at 3900fps and 300yd zero drops 166" at 1000yds.
A .257cal 115 gr nosler at 3600fps and 300yd zero drops 177" at 1000yds.
What velocities are you getting out of your 264's?

Thats according to point blank and using published BCs at 500' elevation.
 
outlaw u aren't being fair as your AI has such a long pipe compared to what others have which is why your fps is so inflated

now I will admit I would have built an AI if either brass were available to buy or I were retired &nd had more time to spend fireforming


and when u compare trajectory in the 25s the 100 grainer wins out no matter which case it is fired from it carries so much better than the 85s or 75s

Ive gotten the same load to 3920fps in a 30" barrel.

I guess someone will have to build a 30" piped .264 Winny to find out... or, we could just acknowledge the laws of physics and internal ballistics.


Look... I could put a NoS bottle on my wifes Dodge Caravan, hit it with a 60 shot and it would haul much azz. Then go and say the Z06 sucks because my "mini van" could run with it. But, would that make either the Caravan a legit "supercar", or taint the reputation of the Z06? No... neither of those are likely. What's more likely is that I blow-up the wife's ride in a short period of time... and I'd still get lauged at by everyone in a remotely fast car.

I love the .25's... but they have their limitations. All of a sudden the .25-06AI is capable of super-human speeds at the expense of 30 years worth of data (and common sense) to the contrary simply because a couple guys on an internet forum post some herculean feats accomplished with rifles using city watermains as barrels? Really?

Outlaw and I have gone the rounds before... and I truly believe the guy gets what he says he does out of rifle rounds... but does that make his numbers a valid comparison to existing data for similar rounds? Me thinks not....
 
uuummmm
You said.
".....264 WM is a helluva round. 10x the round the 257 WBY will ever be. Run the numbers and you'll see why, and which wins out at LR..."
OK
The 257WBY will out do the 2506AI so using my 2506AI data was fair in my opinion.
What makes you say the 264 is a 10X times better round?
Im asking because if I can see the numbers and like them. I'll build one of them next(but I'd likely go with the STW instead).

WHAT VELOCITIES ARE YOU GETTING!!! This is the third time Ive asked in this thread.

Do you want me to run the numbers using my 26" barrel data? Im cool with that.

2506AI 26" shilen barrel 100gr nosler at 3700fps = 188" drop at 1000yds.
115gr nosler at 3400fps =195" drop at 1000yds.
Both data is calculated using published BCs at 500" elivation and 300yd zero.
Surely the 257WBY can get those velocities.
What are the numbers, I wanna do the math.

I dont think the quarter bore is super human but Ive taken elk and buffalo with mine. I done really see the need for anything bigger unless Im after bear.
 
I've take elk with mine too... with 100 NBTs... but that don't make it the end-all be-all of rifle rounds. And... we both know that drop ain't where it's at on a LR gun. Any monkey can run a rangefinder and spin a turret... it's wind drift that makes all the difference.

I could get 3600-3700 out of a 100 in the .264... and 3450 with a 120... I could also get 3200 with a 140... all using a 26" Lilja pipe on a Rem. 700.

Put 3200, 140, .640 BC in your ballistics calculating pipe and smoke that... let us know how it compares to a 100 NBT at 3700 and 115 at 3400... NOT JUST DROP... BUT WIND DRIFT and ENERGY ALSO.

I never said it was 10x the round... remmy did. I said it whoops the .257 Roys azz... and the numbers won't lie.
 
Not bad, 4" difference in drop but 20" difference in windage with 10mph wind. Perty good. When compared to the 2506AI.

What happens when compared to the roy though...LOL
 
What's the energy? I find it convenient that you left that out. I've run the numbers too... just waiting to see if you come clean or not.
 
100 NBT @ 3700fps via Magic .25-06AI (or everyone else's .257 Roy)@ 1000 yards:
Drop (from 300 yd Zero... as per above) = -188.5"
Velocity = 1550fps
Energy = 539 ft/lbs
Wind Drift = 79.25"

140 VLD @ 3200 via .264 Winny @ 1000 yards:
Drop (from 300 yd Zero... as per above) = -185"
Velocity = 1900fps or 22% FASTER
Energy = 1100 ft/lbs or 85% MORE
Wind Drift = 50.75" or 40% LESS

Soooooooo, lets see.... over 20% faster, hits 85 % harder, and has 40% less drift... all for about a 10-15% increase in powder and staying within sane pressures...sounds like an azz whoopin' to me...

Running the 115 Berger will get you closer to 10%, 35%, and 15%... but you still give up a lot... like 30% more mass, and the obvious increase in pressure... Don't know that constututes full on azz whoopin' designation... but it's a substantial victory for the .264 to say the least.
