Thanks Cole........................ Dang, get that dust off  OK, so I got 100 of those 250 Barnes TEZ's today from Carlos--ordered on Thursday and received today  I had mentioned the other day the diameter of the 290's I had gotten from Luke which measured at .4500 to .4501" as checked on a number of bullets with my Starrett micrometer. One member mentioned that that was just the right size to fit his bore. (Rambler if I recall?) Today I mic'ed the 250's from Carlos and they went from .4503 to .4507" which would probably not go down the same bore except with a hammer. This illustrates the need for an adjustable sizing die. Besides getting the bullets to the correct size, it also uniforms them for consistent seating pressure. While I was at it, I also checked the bearing surface on these two Barnes bullets as measured not from the base (as here is a bevel which does not bear on the lands) but from whee you can actually see the scuff from the die up to where the the ojive begins or the scuff mark stops. I also checked the same bearing surface on both the 250 and 300 gr. FTX to compare. 250 TEZ----.520" 250 FTX----.389" .131" more bearing surface on the Barnes 290 TEZ----.660" 300 FTX----.569" .091" more bearing surface on the BArnes So, could this be the reason the TEZ's (at least the 290's since I have not shot the 250's yet) are shooting so well? My guess is YES! Richard |

My guess is YES! Richard I noticed on each bullet there was a little bit of the plastic sticking out. I wonder if shaving it off with a razor blade would be acceptable. Don't know if that would affect accuracy or not.  |

I hope the name sticks then we can just shorten it up when the time comes |

I always clean the plastic up on mine, razor blade would work good, I use a small pocket knife. I like a clean surface free from any possible extra drag or acting like a control surface.

I personally do not believe it would cause any problem what so ever in our ML'er operation? If they were custom benchrest match bullets........Yeah maybe? It conforms too well to the ojive of the bullet and is too thin to matter. But hey, if you think it is important?......take and shoot five with and five without at the same time --same wind conditions, same barrel temperature and fouling (not different days) and report on you findings?

What is the overall length of the 290 Barnes I am guessing 1.230?
Midway shows the 250 as being 1.090 long and the difference between your shank measurements that should be ballpark ??

I shoot thousands of 290 Barnes BT and FB, flat based are the way to go IMHO, never cleaned them in my rifle I sized them to .450.5.
Used it to kill many dimes....and Moose.

I hate to sound like a broken record, but I can't stress enough that the 250 or 290 TEZs are the most effective deer bullets I know of. I admit my deer kills were all with the Spitfire version, but they are all similar and made of solid copper. I know it's been tried but I might try to pop off the tops of some 290s to see if I can anneal them. After putting the tops back on, you would want to be confident that the tops are not tweaked by the process.

Phil.......its been indicated that they have been annealed from the factory and they knurl and size with no problem?

They may be somewhat annealed from the factory but there's room for improvement. Probably not noticeable if you are FFing after knurling up though.
I FFd some .458 barnes a few years back, some as they came and some I annealed first. Those I annealed easily required about half the effort to FF than the factory annealed.
I have also pried the ballistic tips of of the TEZs, annealed them then reinserted the tips. Take your time and it's no problem.

I just annealed some Spitfires and full formed both annealed and un-annealed. Adjustments on the .451 die were ".4" and ".8" respectively. The annealed bullets went through like butter while the others required effort. So I would say that "half the effort" is right on the money.  |

Just what does annealing do to a bullet? If it changes the structure would that not change the expansion cariturelistics for hunting?

The damage done in that photo is typical of what you'll see using a TEZ.... They'll shoot through every time and do major damage doing it....My favorite hunting bullet for a long time Zen |

My hope is that the annealed TEZ would be almost as soft as the Parker BE, which is to date the champion of accurate bullets. If the BE is so accurate because it obturates so well, the theory might work with the TEZ. The TEZ is like a giant Banrnes 195 gr all copper that we shot/or still shoot, in the light blue sabots and which everyone thinks is a good deer bullet. Ohioguy: That is a cool photo of an annealed TEZ kill . I just don't recall what the deer looked like after I shot them with the 250 gr Spitfire, but they all went down immediately when shot across a 300 yd canyon. Those Axis deer are tough and even some little buggers get up and run after being shot by other "normal" muzzleloader bullets. I once watched a guy shoot a medium buck. It made that funny jump so I thought it might be hit. The buck ran about 3/4 mile and disappeared in a small grove of trees. The man went looking around about 200 yards from where he hit the deer, not realizing it was able to run a long ways. Later that day we went to the trees and found the buck dead. It had been shot through the lungs and the bullet ended up just under the skin on the far side. The bullet looked like a regular jacketed bullet of some sort, but it hadn't expanded much at all. I have no idea what kind of gun it was shot from, but it was certainly a lame gun in our view. Compare that with the shock and devastation of the all-copper Barnes TEZ, which is basically a hollow point, going over 2500 fps. Not much runs from that, even if the hit is a bit too far back. I don't think you can get an all-copper bullet to be too soft, so if annealing works and it improves accuracy, I think we can assume it would also expand better and therefore be more deadly. I've now seen some .416 CEB annealed bullets hit and kill about 5 deer, and luckily they were shots that were deadly. But I also saw a little deer get hit with two .416 CEB 340 gr all-copper bullets and then run around for a good long while. The bullet placement was too far back, which was my brother's doing. I never shoot like that. I feel the 250 gr Spitfire would not have allowed that deer to run around. I think the .416 bullets would be better on elk or bigger critters, but they may not expand quite enough on some smaller deer unless you get good placement. I think a 290 TEZ, especially one that is annealed, will put any deer down just so it hits in the main body mass.

Thats a picture of a .400 240gr Cutting Edge annealed not a TEZ. Shot placement is key. Can't blame the bullet for hits too far back.
