Can you make a .25-06 AI perform like a .257 Wby ???

I had been looking for load information on the .25-06 AI ever since I changed bullets and went to the Berger VLD 115 Match bullet. I had been using Retumbo but just was not getting all that great of performance from in from a Velocity standpoint. I happened to do some searching on the Reloaders nest and came up with the below info. This was not the top load listed with this bullet powder combination but looked like something I would like to check out. If this load does what this guys says it will it still has 935 Ft/lb of energy at 1000 yards and is moving at 1913.9 fps according to my ballistic program That is incredible. Drops with it sighted in at 200 gives me a 1.05 rise at 100 and 5.1" drop at 300.
At 1000 yds it has a 18.2 MOA drop
Wind drift at 1000 yds in a 10 MPH full value wind is 5.3 MOA or 60.54"s
IF all this is true I might of found my long range Antelope/Deer loading.
Big question I would really like to know is just how much pressure is this and what kind of barrel life would a person get. I like my .25-06 AI too much to burn it up too fast.

Comment Action trued and blue printed. This load was not max in my gun. Very fast and two rounds were through one hole the other honestly I think I pulled.

60 grains of RL-22 in my 25-06AI produced 3480 with 115gr BT's and I have a 28" tube. Started getting more pressure than I was comfortable with there. Over 3600 is optimistic I think.

I would not trust data from reloadersnest. It is anecdotal and I never see pressure measurements that were done. The 25-06AI is a neat round that can offer a decent gain of around 100 fps over the standard 25-06 but a 257 Weatherby it aint. If you run it in a 28" tube like the previous post you can close the gap a little on the Weatherby out of a 26" tube but I wouldn't use that load in my rifle. You might not hurt the rifle any but I'm betting your brass would be trash after the second firing.

Its too bad their isn't much loading information out there for the .25-06AI. So far I think the cartridge is fantastic but I never intended on it being a .257 Wby or I would of built one in the first place. But finding loads for it is like BUTTS. Everyone has one, no two are alike, some are great and some you want to shy away from. This might be one a person wants to shy away from. I just wish there was some data on it for pressures and such as when I built the gun I had it built with a tight neck. Between having to turn the necks prior to fire forming and then the case forming it can be a bit tedious but I do have fun with it. Haven't found anything it won't shoot well so far though. It really likes to have the cases annealed each time its reloaded though or the neck tension goes array and accuracy with it. Just plain shoots so well I hate to burn it up but I did find this load intriguing.

Not sure on the heavier bullets, but when I had mine it would push a 85gr Nosler BT just south of 3800 FPS in a 25" gain twist barrel. I used the 90gr X bullet as my hunting load in the low to mid 3700 FPS. Took a WT buck at 418 yards & it did the trick no problem. Loved the rifle, then I discovered this.

That's what happens when you try to friction fit a standard thread into a metric Sako TRG-S receiver.

Be sure you know your gunsmith is up to the task. This guy ain't no gunsmith I discovered. A lesson learned that could have been much worse.

Had intentions of building another one, but got a few other rifles after this episode & never got around to it. Good caliber IMO.

BillR, In a word, NO! I have shot and reloaded for my .257 WBY for over 40 years and I would have to push it VERY hard to shoot that bullet at that velocity. It you chronographed that load there, I Think I would have the chrony checked.
