.257, .264 or .284 caliber bullets with good BC and expansion for PD?

If the Dogs Are not fly'en...I'm dying!!!

Heavy recoiling rifles are not fun for me. If you can't see your impacts, you will not how to correct for elevation and windage. My 243AI's weigh 28 lbs and have muzzle breaks...I see all the action.

I Too have the 257 Weatherby with zero freebore, 100's going 3800-3850 in a 26" barrel with Vias break. This is a deer rifle and I see the bullet impact the deer.

If you want to build a really fun and super accurate rifle, then the 6mm Ai with zero freebore in a 12 twist shooting the 75g V Max at 3800+ or the 70g Blitz king at 4100 is your answer. P. dogs just simply vaporize or shoot 30' straight up or sideways! Ever kill a p. dog with another p. dog? Just put a little English on them! If you see 6-8 p.dogs on one mound, shoot the very top of a couple's heads off, plugging up the hole. Then get the rest of them, starting with the ones on the outside edges and work your way in. If this does not sound like fun to you, stay home and shoot targets! P.dogs are pests to the ranchers that are infested with them.

To heck with saving a gun barrel, they make new gun barrels every day! How often do you get to make some memories on a dog town?
 
Artist,
I don't have a Sierra book, but my Hornady book lists a max load for your 100gr soft point 257 Weatherby as 3400FPS. I don't know what you're doing to get an extra 500-550fps over that, but yes, at that velocity it is superior down range to most anything anybody's 204 or 224 could ever deliver. Sounds like fun.....and quick barrel replacement too.

With the right setup a .257Wby will shoot 100's very fast, very accurately. Mine has the same 0 freebore chamber as Keith's and 100's are doing 4010 through a 29" Hart barrel. The key is 0 freebore with a close fitting neck, and PMC brass which is stronger than anything else made for this cartridge. This thing would surely vaporize a prairie dog but I can't see using a 100gr bullet and more than 70gr of powder on a creature that size. The gun is used strictly for rockchucks.

About the other stuff, Keith's right. Lots more fun when you can see exactly what's going on. Nitpick over chambering and everyone will have their own favorite, but gun weight and a muzzle brake raise the fun factor with pd's. Even my .223s are braked and the 6mm's all weigh over 20lbs, they go bang and just sit there.....at 32X you can see the whole show. I've shot them with a 85/87's at 3650-3750 from a 257AI and that gets the job done fine. You can endlessly compare numbers on paper. But actually being out there shooting and dealing with all the real life factors, it's hard to beat a 6mm with 70's or a 22-250AI and 50's at 4200+.
 
Right now I have a 22x47Lapua varmint rifle in the works that was built strictly in mind to use the .435BC and .453BC Hornady 75 & 80 grain Amax bullets. This aprox 22-250 sized brass case shooting either the 75 or 80 grain Amax will make the performance of a 25-06 or .264-06 cartridge look really inferior......and needless.

Watch out for vaporizing bulleting out of the 2247L at somewhat low velocity if your twist isn't just right.
