The seater with the collet neck sizer will not crimp. Not that I would want to crimp anyway. It's their so called dead length model. When I've gotten good ones of those I've found them useful for finish seating bullets in well compressed loads when the bullets have been started straight in a more precise die that doesn't do well with powder compression.

I don't crimp with seaters, anyway.

I have a factory crimp die if I want a crimp. Sometimes if I have light seating with mild bullet/neck tension, I may add some crimp. Good thing about the Collet die, you can cut some off the mandrel to increase bullet/neck tension.

Chuck the mandrel in a drill and cut it down with sandpaper, measuring pretty often, so you don't have to buy another one and start over... shocked

Never had to do that... cool

As a follow up on the Lee FL die, I took my Dremel and with a small grinder, enlarged the die neck to clear the case neck. It's now a body die with decapping/expander stem removed.

I checked sized cases. Some are pretty concentric, some aren't. With a very tight neck and hard pulling expander, cases thinner on one side ended up crooked, those with more concentric construction remained straight. That's the only explanation I can come up with, as they were all handled exactly the same. Not much difference, Rem. vs. W/W.

I'll load the crooked ones and straighten them as much as possible with the Tru Tool. Once fired, the Collet Neck sizer should keep them concentric.

Follow up on the Roberts project.

I took gunner's advice regarding the 100 gr. TTSX. He suggested loading for meat, not paper. He said to use Hybrid 100V and run that bullet at 3,200 fps.

Well, sometimes you can have your cake and eat it, too... cool

46 gr. 3,188 fps., .70" at a hundred (three shots).
47 gr. 3,266 fps., .438".
48 gr. 3,328 fsp., 1.7" and getting warm. Bolt lift was OK, case head with some bright spots from the bolt, primer OK.

It appears that the 100 TTSX at 3,200 fps ahead of 47 gr. Hybrid 100V is a great load, super accurate. This gun has done well with the 115 NBT, but the TTSX shot the best group so far. 100 and 115 gr. NPT's and the 117 SST's were pretty good, a few stand out loads, the TTSX is the winner.

I think I can settle of gunner's load and go kill stuff.

BTW, here are photos of a high classed shooting range. Note the magnetic gun rack stuck to the Z-71. I shoot three shots with big guns, five with smaller ones, let the hot ones cool in the rack with open bolts while I shoot a cool one. I can keep five or more guns going without any getting too hot and without losing time. This morning, I started early while it was sorta cool and shot until 11:30. I shot two batches of 10 targets in the far left distance, each target with two bulls.

Hell Yes!!!!! congratulations DF, glad you gave that little buzzsaw load a chance, now all you have to do is get some hair in that scope, then look for a bullet to recover for examination.

I haven't found one yet. cry laugh

Would a Redneck shooting set up like this work in OK?

Yeah, I'm going to start the WT season with this gun and that bullet.

Thanks for the load, it works just like you said, even at the speed you quoted.

Yessir, I'm a mid to high shoulder puncher, you'll lose a handful of fajita meat at most shooting them there with this setup.

The 100 and 80 Gr TTSX are my favorites in all of my 25 cal's. What COL are you loading to? Factory??

Thanks for the loads, BTW.

Longer than factory but with .050" jump. I'll check for more precise info this afternoon. With the LA 700, COAL isn't an issue.

I'm fortunate that this gun, even with the long action, is one of the slickest feeding bolt guns I own. No matter how the rounds are positioned, it feeds smooth as silk.

Wrong info. I was going to jump it .050" but went with .030" becaue of the grooves. I could crimp in the second groove this way.

I know, I know, crimp's not necessary. But, it looks good... smile

And, I get to use my Factory Crimp die... cool

With this round, I used the Collet Neck sizer, then had to bump the shoulder with my improvised body die for easy bolt closure. These loads were pretty warm. At least this batch is very concentric, this is a Nosler +P case. The Lee FL die was terrible, but made a good body die... wink

Here's the target. As you see, this COAL wouldn't work in a SA box mag.

I made the comment, no telling how good this gun would shoot off the aluminum tail gate of a new F-150. But, I just realized, my magnetic gun rack won't stick to aluminum.

Guess I'll have to stay with trucks made of iron...

It probably isn't a factor in your country, but in one of my tests H100V lost more velocity in cold weather than any other powder I've tested, 186 fps from 70 to zero. Now, this was with 165-grain bullets in a .30-06, and temp-sensitivity is to a certain extent dependent on the specific application, so it might not lose as much in your .257, and as I noted it may not be a factor in your hunting.

Thanks, JB.

I had read that before. I think you wrote that powders with tightly specific performance niches tend to be more temp sensitive. I hope I said that right.

I can clock this load when it's cold, say 30*, and report any difference from 80* or so. You guys get into sub zero weather and I can appreciate the need for the least temp sensitivity possible.

The way this powder performs in the Roberts, I could put up with some of that. This is not going to be a LR gun, mostly under 250 yds. I don't think I'll have a problem.

I have other guns for extended ranges, like the 26 Nos.

This is how I turned the Lee FL into a body die. I'm pleased with the result.

DF,

Yep, you read that right.

I've had excellent results in the .257 at "normal" temperatures with H100V.

I need to make a correction. I posted that the 100 TTSX/46 gr. H100V load shot the tightest group. Actually that honor goes to the 115 NBT/44 gr. H-4350 load which shot three into .357". Statistically there's not enough difference with only three bullets each to declare a winner.

I guess I was excited about the performance of the TTSX running at 3,200+ fps. that I sorta forgot about the other load.

I haven't clocked the 115 NBT load, but it should be in the 2,900+ range out of the 24" Brux. It should also be a good WT/hog load. Next time I go to the range, I'll clock it and report. Fair is fair... grin

Believe me, the 115 at 2900+ kills very well.

Ya'll are reminding me I have a .257 Kimber that needs blooding.

I have one lb of Hybrid 100v, plus a few bullets I used last year developing a load for Dad's old .25-06. Real interested in trying some Big Game in the Bob.
