Welcome to WBY Nation Woodsman!

I have 2 .257 Weatherbys and I run the 110 Accubonds in both of them. They are amazingly devastating on deers and hogs. Iíve put a couple of 280+ pigs on the ground with them easily. Like turning out a light. Almost every deer I shoot with them are bang-flop, DRT kills. You will not be disappointed with the 110 Nosler Accubond coming out of a .257 Weatherby.

I agree with you about the quality of  glass in Vortex Diamondbacks, especially for the money. I use a lot of Vortex products and have 2 diamondback rifle scopes and a spotting scope. Not a complaint about any of them.

sorry to hear about your wife Doug, that's terrible. I just got married last Saturday so I can't even imagine. 
 yes I have been very pleased with the quality of vortex optics. eventually I imagine I'll upgrade to.vipers on these 2 rifles, but I bought my 1st house this spring so settled with diamond backs for starters.  you guys are correct on the accubond weight, the bullets I was shooting were spires. accubond was just in my mind because that's what my grand father told me he shot out of the gun. gonna order some in the morning and give them a try. thanks everyone for the welcomes, seem like a great group of guys. anyone able to date my gun off a few pictures?

Post your serial with the last three numbers XXX'd out, and I can review a serial reference and give you a rough idea.

Dubyam,They changed the twist rate while still making them in Germany.They started making them in 1 in 10 in the 257 around 1967 or 1968.Before that they were 1 in 12.
Sorry... Yesterday was the last and final day for any and all complaints whatsoever.

Weatherby recognized that people were going heavy for cal earlier than this,and refused to change the twist rate earlier.He stuck to his guns,no pun intended,on speed kills.With light bullets,being pushed hard,you just didn't need the faster twist rate.People forget that he was pushing the envelope for speed with .224 bullets way before he developed the 270 Weatherby.

I have seen 257's with 1 in 10 twist barrels with serial numbers in the P23,000 range.I'm sure yours in 1 in 10.

Along with Weatherby was Savage. The 250-3000 was designed for light bullet weight and high speed for its day. It also had a slow twist rate

Okay so I ordered a box of 110g nosler accubonds, finally got out to shoot this week and they at least "group" but not good at all. I'd say they were about 4 inches at 100 yards.  Is there another type of ammo I should look at or should Into sending my rifle in for someone to have a look at it?  The far right shot was with a clean bore, so I expected that to be off. Shot about 20 shells, and cleaned the bore  twice during shooting with hoppes copper fouling solvent

I would try another scope first, with groups that bad I doubt if it is a barrel problem.

Welcome to the Nation Woodsman. Did you switch scopes, or is the Vortex Diamondback the same scope you had on the rifle when you sighted it in with the 100 gr. accubonds originally?

Also (and I don't know if this was mentioned earlier) is everything tight? Action screws included

Same scope, had fairly low round count on the scope, but I can try that.  No I haven't checked all that,  what would the torque specs be on that

35 inch pounds (not foot pounds) on the trigger guard screws. Torque the rear first to 20 inch lbs then the front and then torque the rear to 35 followed by the front.

Scope bases and rings should be 15-17 inch lbs.


Having looked closer at your targets and re-reading the entire thread, the bullet is key holeing on you. Even with the 1-12 twist that you have the bullet should stabilize before 100 yards. I'm now suspicious of the barrel condition and would recommend having it inspected with a bore scope. That may tell you what your next steps are. I would be hesitant to recommend hunting with a rifle that's keyholing. The bullet may not expand correctly and may cause a lot of damage without a kill. Ultimately that's your call.

Make sure you clean the barrel and when you think your done clean it again.  The Barnes bullets WILL copper foul youíre barrel like crazy, especially after you have shot a different bullet previously.  One of the reasons I will not use them.  Unless your hunting elk any non varrmint bullet will kill thin skinned game.  Pick the one that gives you the best accuracy.  On your guns accuracy,  a shot out barrel doesnít happen over night.  It gets progressively worse, so I doubt thatís your problem.  Clean the barrel with some good copper solvent, itís cheap and easy to do,..... and I bet it fixes your problem.  If it doesnít, take your Vortex back and get another one.  I personally wonít buy anymore Vortex products  no matter how cheap they are or how good their warranty is.
