Looking to build a smaller caliber long range hunting rifle. I have debated on the long versus short action. I'd like some food for thought on the two calibers from ballistics, availability of quality HUNTING bullets, and first hand experiences. I need to *hit or get off the pot.
Thanks in advance [img]/ubbthreads/images/graemlins/wink.gif[/img]
These are two very different rounds that you are comparing. The 6.5mm-284 makes its living with long barrel life, easy loading and pushing high BC bullets to moderate but solid velocities.
The 257 Wby, with traditional bullets uses a bit more raw horsepower to muscle bullets from 100 to 120 gr out at high to hyper velocity. Barrel life is shorter but it properly cared for, nothing to worry much about.
If your going with a custom rifle, here is another twist on the 257 front. Richard Graves has designed several different heavy for caliber 257 bullets that are performing extremely well. They range from the standard 100-120 gr bullets up to the 130, 142, 145 and the huge 156 gr ULD RBBTs.
FOr your needs the 120 and 130s may be the best options. I only bring this up because these bullets bring the 1/4 rounds up where they should be in performance with the 6.5mm bullets.
If your looking for an easy to load round though I would look at the 25-284 or the 6.5-284. Both are basically ballistic twins when using bullets of equal BC value.
I would personally go with a 25-284 or a 25 WSM before the Wby but that is just me personally.

I have heard reports that the 130 gr FBHP bullets are working well in the 25-06. The 100 to 120 gr will work fine in most 1-10 twist barrels. Some of course will not like the longer bullets. Richard makes two versions, one on a J-4 Jacket and one on a heavier jacket designed for the big 257s like my Allen Mag, I would say the lighter jacket would perform best in the 25-06.
That said, Richard has been having some problems with the J-4 Jackets here lately so I do not know the status of that jacket option. Seems they are making the jackets to hard which causes some serious problems inthe forming process.
About 6 weeks ago I tested and chronographed Richard's 130 BCFBHP and 142 grain ULD in my custom 25/06AI, which has a Sako L61R action, and Shilen SS 24 inch 1 in 10 twist barrel.
The 130 grain Wildcat achieved many sub 0.5 moa 3 shot groups, at velocities ranging from 2850 to 3150 fps. The best group measured .185 moa using 65.0/H870, and on first showing, these bullets seemed to deliver similar accuracy to the Nosler 115 BT.
The 142 grain ULD achieved 3050 fps, but failed to stabilise, which was no surprise to me considering their length of 1.365 inches, although Richard has one client who surprisingly reported they shot well in his 25/06.
I have since ordered some more 130 grain bullets, and any of my future 25 cal rifles will have at least a 1 in 8 twist barrel, so that I have the flexibility to use bullets of 130 grains or more.
Over the coming months I hope to use the 130 grain BCFBHP's in the field (in Oz), and will report back then how they performed. Hope the above helps. Brian.
I have recently returned from a successful bear hunt and while I was making the 18 hour drive home I was thinking of my next hunt. I have had a really bad itch to shoot an antelope. With that said, I am looking for a weak excuse to acquire another rifle. [img]/ubbthreads/images/graemlins/wink.gif[/img] (Like my .270, 7mm WSM, or .300 Ultra wouldn't do the job)
I have 2 Rem 700 rifles that I could use as donor rifles for the action but they really aren't the best choice. The LA is a Rem Titanium chambered in .270 win and the other SA is a Rem 700 Light Varmint chambered in .22-250. Both have blind magazines.
Maybe I made a terrible assumption that I could use the SA .22-250 action and rebarrel for the 6.5-284. The case diameter is the same @.473". Now the OAL is a big difference at 1.912" .22-250 versus 2.170" 6.5-284.
While I am an avid shooter and hunter of your standard caliber, this rebarreling and such is fairly new to me.
