Has anyone shot any deer with the 257 Weatherby and factory 115gr Ballistic tips? They shoot great out of my Vangaurd but I have only made two kills with the combo and I was surprised that either buck could move after impact but both did. One went 20 yards and the other went 45. Both were boiler room shots , one at 90 yrds and one at 165. I am not really complaining about the performance, but more wondering about others experiences. I previously shot 120 Partitions but I was having problems with the tips deforming in the mag and it was effecting accuracy. Thanks in advance.

barnes triple shock is what i shoot. cannot go wrong with em.....

Are you shooting 100gr? as far as I know, that is the only factory round in triple shock. I could be wrong though. I prefer a larger bullet but let me know if there is something else out there.

yes 100 grn. tunaman.

It seems that 1 going 20 yards & another going 40 is not bad. How much terminal damage was there?

Tunaman · « **Reply #5 on:** December 16, 2007, 12:17:17 PM »

The Meat damage was not bod on either. the one that went 20 was a pass through and clipped both lungs deflating both. The One that went 40 I hit 1 lung and imploded the heart but the bullet failed to exit. I am heading to the camp for the next week and I plan to shoot this gun most of the time. We have some colder weather and the rut is really getting going so, I hope to have a few shots. I will keep you informed.

Sounds good & I appreciate the info. Concerning the TSX, we used the 100 & 115 in WY on Mule Deer, Antelope & Arkansas Whitetails. Both bullets worked, but the 100gr. did not have the quick kills we liked at long range, some Mule Deer ran a little further than what you experienced with the 115BT. The 115TSX killed as quick as about anything, but the BC is not that great & they dropped more than we liked. Both will give pass throughs. The 120NP did good on all counts! The Wildcat 125's fly better than all, but I am not sure yet about close range shoulder shots.

How much do these Caribou that you are shooting weigh?

Sorry about the time gap, I have been doing a lot of hunting and some fishing and I haven't had the computer with me much. I took 2 more deer with the 115 ballistic tip right before Christmas and both were clean kills as well. one on a 195 pound 8 pt that was chasing a doe and fell drt and one on a 125 pound doe that also fell drt. I feel pretty good about this load. After those two I retired the 257 for the season and have been hunting with my 7mill and 50 ml. Both have made kills including a very nice 10 pt with the ML. Thanks for all of the help.

Hey Tunaman
Sorry I did'nt get back to you before since I work offshore Louisiana on a supply boat. We used to fish out of Orange Beach Alabama.
I have a beautiful 257wby and it shoots the 100 gr. Hornady spire point pretty good. It does'nt like the boat tails very much, but I hear the Barnes is the cat's meow for that 257 and I will probably try them. Hope this helps.

Thanks 31,
I have a buddy that is shooting 100gr triple shock and they have been great for him as well. I hope that you are on a 220 as that weather has been really bad. I have only fished 3 times this year and we have serious weather coming in tonight. Good luck,

I'm on a 288 footer and I wish you was out there with me about 2 weeks ago, Tuna all around our boat, a flying fish flew on deck and I throwed him back over and was imediately devoured by a hungry yellowfin. Our company does'nt allow fishing. That kinda sucks.

Yeah, I have shot whitetails with the 115 ballistic tip factory ammo. Did not take a step, but every animal is different. These will shoot 3/4" groups, but the 100 grain sp factory ammo shoots less than 1/4" so that is what I am shooting now.

I shot a fat body mule deer with a 115 BT out of a 257 roberts once. He went about 20 yards and fell over. I would think out of the wby, it would be at least as good, if not better?

The 115 BT is my bullet of choice for my 257 wby mag.

Never owned a .257 but have shot many deer with a 25-06. Have had similar experiences. Does not always put a deer down, and some will run a ways. Same results with .243. Moving up to 7mm-08 and other .284 loadings, they don't usually take a step.

There is no absolute guarantee with any caliber. A drt shot might not result in a drt. I blame the whitetails.

Kinda late seeing this.

Hate to break it to ya but you need to find a new excuse for lack of accuracy with the PTs. The nose of the bullet has almost zero affect on accuracy. That ain't what caused your problem.

Tunaman · « **Reply #17 on:** January 07, 2009, 01:15:35 PM »

I don't doubt your wisdom but how is it that a deformed bullet not effect accuracy? I have actually switched to a hand load 110 acubond this year, so it really is a moot point, but I am interested to know why it wouldn't change anything. Thanks in advance.

I too am hoping to find a proper load for my .257 Whby. with the 110 AB but am also going to try the 115 and 120 PTs as well.

In a recent magazine article they did about as extreme a test as I've seen on the impact of bullet nose deformation on accuracy. I found out long years ago nose shape has about zero to do with accuracy.

In the magazine article they used snips to cut off the nose of bullets and some the ground off an an angle not even always the same angle and I think took pliers and mashed some others. There were several different methods used. The bottom line result was that none of them had any real affect on accuracy but even a small nick placed on the base of the bullet had a major change in acccuracy causing them to go all over the place. It is but the latest of many tests showing same result I've seen written up and yeah I've done my own tests many years ago showing the same.

Tunaman · « **Reply #19 on:** January 08, 2009, 03:52:31 AM »

That is very interesting and I never would have thought that. That is one of the neat things in life, if you are doing it right, you should learn something new each day.

I am loading 63.2gr of 4350 under a 110ab if that helps. I am just unser 3300 but i can't find my notes as to the exact speed. I have tried a few powders and this is the one that worked best for me. Good luck in finding your load.

GB is right, I've seen similar tests published numerous times in the past 30 years with the same results at the test range. However, that result is in reality only partly true. Differences is accuracy at 100 yards may be meaningless, but at longer range the widely different BCs of the randomly modified bullets would have much more effect on where the bullet lands on the target. I'd expect 500+ yard groups to be considerably larger due to the inevitable vertical stringing....if that matters.

Graybeard · « **Reply #21 on:** January 08, 2009, 07:25:49 PM »

I'd certainly agree with that logic for the bullets mangled in the tests but not really so much so for those more slightly mangled by recoil in the magazine. Quite honestly I've never been able to find a difference with them at any range I've shot out to. Many folks seem to think the exposed lead tip actually melts off anyway soon after leaving the barrel and I've seen a couple photos taken at super high speed that seem to back up that theory.

Lone Star · « **Reply #22 on:** January 09, 2009, 10:05:15 AM »

Not only might the lead tips 'melt', but the brutal acceleration can cause tip deformation by lead slump, blunting the tip before the bullet exits the muzzle. But the effect on group size should be minimal since the slump would be identical from bullet to bullet. The POI would not be the same as that predicted by the tables since the actual BC of the bullets would be lower due to the blunt tip. All in all, not something to worry too much about IMO.

The article that I remember they used a very accurate bench gun in 6.5x55 cal. They showed pics of the bullets as they gradually filed the tip off to one side and shot them into one hole @ 100 yds. Even with a large slant on the bullet tip it was still going into the same hole but when they made a slight cut on the base that destroyed the accuracy. Long range you'll see more drop from a flat point but otherwise not much difference.

I am a bit confused - we start out discussing Nosler bullets and then jump to Barnes. BT's are no match to Barnes IMO in caliber above .224 IMO to be used on midsize or larger game.

My experience with the 257 Weatherby and 25:06 is similar - for ranges over 350 yards they want to go fast with a sleek bullet; short range accuracy for predator control is OK at 85% of full throttle with something like a Vmax bullet. H4350 and Norma brass. For hunting the Barnes or Hornady bullets perform well on less than perfect shots.

Projectile performance is really is rocket science - bottom line is as Graybeard points out: bullet tip deformation is mostly immaterial to bullet accuracy in particular as contrasted with the effects of the bullet base. Here is a quick read on the subject - http://www.stormingmedia.us/32/3217/A321714.html if you want to go into details. It may help to picture it as an airflow issue such as with an airplane, rocket or arrow - they don't put rudders, fins or vanes on the front of the projectiles for a good reason. You can glue a thin rubber strip made from an inner tube patch in your magazine if you have enough room to cure the deformation problems.
