I read that article by Simpson, most of it is bunk. Layne is trying to sell people on the 7mm STW and .257 STW cartridges. The .264 Win Mag is a direct "competitor" for these two cartridges, sot to speak, so Layne is trying to eliminate some competition here.
I measured some of my .264...
1-pointer,
Yup. The way I do it is to screw the die in so that it touches the empty shellholder, then back it out about three turns. Now place a fired case into the shellholder, and run it up into the die. Inspect the case neck, you should be able to tell how far down the neck the die has...
WD,
I don't think there's any right or wrong way to do it, as long as one understands (and you do) about full length sizing working the brass more, and accept shortened case life.
1_pointer,
Full length resizing every time does two things:
1. It forms the case back to standard dimensions...
Just kind of curious how some of the "powderheads" (we called the car guys in high school "motorheads", so I made up my own term for reloaders) on this board size their brass.
Full length resizzing will definitely shorten case life, I learned that when I first started reloading. I'm curious...
Honestly, Dan, I don't really know at what position on the clock face a rifle shoots most consistently, but I read long ago some guy stating that 12 o'clock was the most desireable. The theory was that at 12, there was less chance of the barrel contacting the stock due to the barrel heating up...
Here's a system I use to find a good load for about any suitable powder/bullet combo:
I load up "pressure testers", one cartridge for each load, starting at what I think will be 10% below max, and work my way up to, and a grain or two past estimated max, in .5 grain increments. They are al...
One thing to be VERY careful of on digital scales is their tendency to rezero themselves if you are trickling powder onto them. What happens, and I know from both my experiences, and those of others, is that the scale is constantly adjusting itself for slight discrepencies in atmospheric...
I think the stories are beginning to "grow" about that lot of powder. I have some, and called Alliant about it. They had some questions about my experiences, and said that they'd had mixed reports about it from people. I am happy with it, so I then went out and bought the other four canisters...
I haven't used MRP, but a powder that gets you in the same ballpark is Re 25, which is manufactured by Norma then private labeled for Alliant. I don't know if it actually is MRP, but if not, it's very close.
78 grains of it will send a 200 grain Partition out of my Ruger .300 Win Mag at 2,920...
Dan, I agree with you 100% about the RUM cartridges. Unfortunately, lots of people evidently have bought the whole marketing thing, because I see tons of the .300 and .338 RUM chambered rifles on dealers' shelves, and they tell me that they are selling well.
Sooo...I think that the powder...
90 - 100 grains of powder per shot? For a 7mm? Mama-Mia, I should have invested in powder companies before Remington announced their RUM cartridges! :eek:
Whitedeer,
I think you mean 7,000 grains to a pound.
437.5 x 16 = 7,000.
When I'm loading up my .338, the powder does seem to disappear quickly, but not THAT quickly. ;)
Only living thing I've shot with them so far is one unlucky jackrabbit who was in the wrong place at the wrong time.
At about 150 yards, he was torn into little pieces.
130 grain SSTs are the most accurate bullets in my .270. I've measured three, three shot groups that average .485", and a ten shot group that measures .708". All ranges were 100 yards.
I like 'em! :cool:
I have a .264 Win Mag that loves 140 grain Barrnes XLC Bullets. I'll be using that rifle/bullet combo over bait this fall.
All of my bears so far I have shot with 180 grain Speer Grand Slams out of a .308. They all exited, and every shot was through at least one shoulder.
Thought I'd try...
Bullet stabilization has many different factors affecting it. Obviously length of the bullet vs. twist rate, but others are also involved, such as concentricty of form, fore and aft point center of mass, bearing surface length of bullet, etc.
When a bullet is spinning in it's flight, the point...
How many groups have you shot? I don't put much faith in one three or five shot group. I prefer to shoot either four three shot groups, and average them to get an idea of a load's accuracy, or I'll shoot one ten shot group, allowing proper barrel cooling between shots.
I have found that a 10...
Yes, like everybody says, it's reloadable. HOWEVER, I acquired some W-W Super nickel plated .338 Win Mag brass, and experienced some pressure problems with tried and true loads. Upon further investigation, I found that the necks were abnormally thick, and had to be turned down with an outside...
OK Swift, you've piqued my curiosity. Let's hear the reasons behind your choices of dies.
I'm dying to know, especially since my favorite dies weren't on your list. (The OTHER green ones)
