7mm Sickness

Recommended Posts

I have a sickness. I can't leave a load alone, always having to try new things to pass the time.

 

After the AZGFD shoot this weekend, I picked up a box of the 7mm 168 Barnes LRX to try out. I would have grabbed some 6.5mm 127 LRX too, but Sportsman's was out.

 

So I figured another thread on load development was due. To chronical my sickness for my wife to use against in the divorce proceedings if I don't knock off the spending....

 

I had 22 pieces of brass that were out of spec from my original brass buy that have just been sitting in a plastic box. So I figured I would use them for this round only, and keep them separate from the rest of the 228 pieces of brass I already have loaded.

 

I figured the 168 LRX would make a good high velocity close range (out to 500-600 yards or so) round, to be used on elk and deer. I have used Barnes before in a number of cartridges with good results. I shot the .308 175 LRX in my .300RUM @ 3350fps, the .257 100 TTSX in my .25-06 Ackley @ 3580fps and took a big muley at 488 yards, and shot the 100 TSX in my .250 Ackley Imp. and my older daughter took a muley at about 200 yards. We also used the 150 XFB in my old .270 and it took a couple elk, and a couple deer very cleanly.

 

This is the bullet seated to the lands in my rifle.

These bullets are really long. This is next to the 183 SMK that I have loaded with a .0600" jump. Barnes has a 1 in 8" recommended twist. But the 183 SMK states the same thing, and they shoot lights out in my rifle. I also ran the numbers through the Berger twist rate calculator, and they are right on the edge of marginal/comfortable stability @ 1.65 if I push them to 3050fps which might be doable, and at 40 degrees and 6000ft. AMSL.

My data book with the bullet and cartridge info for reference

I resized and threw the 22 extra cases in the tumbler since all the rest of my brass is already loaded.

 

I know some of you may have heard the term, "A watched pot boils no faster." I think the same can be said for a tumbler when you want to start loading a ladder test....

Don't worry Lance, she would never divorce you. Half of nothing left to spend is still nothing!

I will take whatever you don't need. Thanks John. And you can grab that scope when you are there too.

Man do I love when you post something new. Look forward to seeing the results. After you posted the results of the g&f shooting test I sure liked the way that copper bullet mushroomed. thanks for posting.

I took down all the bullet info in my book.

And loaded up a ladder test.

I always mark my loads with different markings for the charge weights during testing. My brother dropped a box with the rounds in order that were not marked, and we had to pull them all apart and weigh the charge weights again and reload. What a PITA.

This is seated .0500" off the lands per Barnes direction.

Hopefully shooting some tomorrow, because I had to work today. We will see.

Hey lance, you ever work up loads for other people or just your own stuff? Ive got a .308 I bought a couple years ago that I wanted to build something out of, but really dont have the time to mess with it. Ive got decent glass on it and dropped it into a hogue overmolded stock with the pillar bedding, and bought a timney trigger that I havent gotten around to install yet. Im not opposed to changing barrels if necessary, but would prefer to see how well the original can do first.

 

Something you might be interested in? Theres absolutely no hurry or timeline either. Just a thought.

Lance did a full load work up for me. That load is amazing!

He does great work and is a great guy.

As you can see, I do load development for quite a few people.

 

It just so happens I have a set of .308 Win dies already too. I worked up a load for another guy in that cartridge.

 

I only do one load development at a time though. It allows me to concentrate on that specific rifle, while not consuming every minute of my free time. Usually takes me 4-6 weeks to do full load workup.

That sounds really good, and like I said, there is absolutely no urgency at all. I only punch paper with it anyway, and the last year has been so busy it's been a safe queen.

I'm heading out for a two week road trip with the family at the end of the month, so I'll get in touch with you when we get back & we can work out an arrangement.

Thanks.

Matt

I got out early Sunday while shooting another ladder test for a .300WM I am working on to shoot my own ladder test. Looking at the target, you can tell I had really calm winds for the first 5 shots. Similar to the .300WM target in the other thread. Then the winds kicked up a bit around 6:00AM.

I will be concentrating on the 5/6/7/8 shot node. I had some pressure signs on the high node of 11/12/13. But the speeds should be plenty for shots out to 500-600. The velocities surprised me a bit with the powder charges. But I know the chrono was on, as my 6.5 SLR rounds were right on the money, and I shot it a couple times throughout the testing.

So now I just have to get some rounds loaded up for this weekend of shooting for groups.
