250- 290 tez

Can't help answer your question directly, since I have a bolt gun but the 250 tez do shoot well with a straight charge of 4198 out of my mcgowen. A lot of people don't have much luck with obturation and Barnes over a straight charge, doesn't seem to be a issue with my mcgowen?

I have a Douglas barrel on an H&R recv'r. I had trouble with the TEZ's but I'm almost positive that I didn't have them sized right and I also think they'd do better out of this barrel with a little duplex'ing. I know some do well with singles. Like a dummy I gave up on them before I could round up some decent booster, I mean some fast stuff like Blue Dot and hotter. I've got some Unique also.

I sold the TEZ's to Richard so you can expect him to chime in any minute now....to gloat on such a good deal I gave him....LOL

They really need a booster powder to perform well They DO NOT actually obturate. I have 2 250gr TEZ's that were shot back to back into water filled milk jugs at 2800 FPS. They both penetrated 7 jugs and stopped in the eigth. There is no groove from the lands, only a dark line. I believe they swell a couple of tenths when hit by the boosted charge but return to their normal diameter after leaving the barrel. I will bring them to the shoot

25" Savage centerfire short action with Pacnor 25" barrel. Smooth sized only. I never knurl after sizing. I doubt that you could get them down the barrel if knurled after smooth sizing. My barrel is .4505 ID and they almost fit unsized but they fit well after running thru the smooth die on a low setting. The 290 TEZ is a couple of tenths smaller and it will take them unsized.

I have shot them in my H&R Ultrahunter but they weren't super accurate like the lead jacketed bullets it shoots well.

I have a black/blue H&R 45-70 conversion with williams fire sights that I use for woods hunting and I shoot the 250 TEZ in it unsized over a boosted load and a wool wad at around 2600 FPS.

BTW, most have found that they tend to shoot better smooth sized. Some guns just don't like them and others love them.

I use 10gr of imr sr4759 as the booster and 50 or 55 gr of H4198 depending on outdoor temps

You could try UNDER sizing them......then knurl up slightly. This would give a better shot at getting into the rifling a little. (if you OVER knurl, then just size back down to what you need?) I have not had any luck with a single charge on the TEZ's but have shot some dynamite groups using a 10/60----Clays/H-4198 duplex. I shot them at the Kentucky Challenge last year and managed to place third with a lot of hard competition.
As far as GLOATING over the ALLEGED deal on those bullets from Mr. Steve Rambler, "Not my fault he could not figure out how to make them shoot?"

Yeah, Yeah, Yeah......LOL     

I have shot the 250 gr TEZs out of my Apex SML.

They go down my barrel without any sizing (lucky).

With a duplex load 10/48-50 of 4759/4198 this load is shooting MOA at 100 yds for me.

Took a buck with it this year quartering away at about 60 yds, hit just in front of diaphragm/behind near shoulder came out offside, base of neck.

Knocked him right off his feet, DRT.

I'm happy with this set up.



Also, the TEZs have performed pretty well for me & my hunting partner out of our "regular" ML's using BH209. 4 bucks between us in the last 2 years, 1 went 100 yds with a lung shot, the others dropped within 30 yds. Recovered 2 bullets and they were perfect mushrooms/flowers.

So far we haven't have any significant meat damage because most shots were front quarter shoulder/lungs.

The buck I shot with the Apex/TEZ this year had a .45-.50 cal entry wound and about a 3/4-1" exit hole. It went through and out, not recovered.

Upon field dressing is was easy to see significant internal damage and huge blood loss. If the deer had managed to run off, it wasn't going far.

With his TC Encore & BH209 & 250 TEZ my partner shot a buck at 100 yds through the onside shoulder and the bullet lodged in the off shoulder. Recovered bullet and it was a picture perfect mushroom and dropped the deer in his tracks.

Granted, the velocity wasn't what a SML will be, but for hunting, I've been pretty happy with the TEZ's so far.

I've got good kills, decent blood trails, minimal meat damage and good accuracy.

If I had to hunt with 250 gr TEZs the rest of my life, I'd be happy.

With that said, I'll still continue to look at other bullets like the Parker MH, the Pittman Accumax and the BOMB. as it is our nature to always look for something better.

Some other bullets show better paper accuracy, but my experience with the TEZ's is that they have PLENTY of hunting accuracy inside 250 yds.
