Well, wait a minute. You say these were fired in your own rifle, right? So, is the photo before resizing, or after? If they look like that after firing in your rifle, then I would suggest you need to take a good look at your chamber. If they look normal after firing, but take on these dents...
One thing's for sure....they are curiously uniform in shape. And that one at the bottom sure looks like SOMETHING is either in the sizing die or the chamber, whatever the case may be.
Cartridge : .30-06 Spring. (SAAMI)
Bullet : .308, 180, Nosler PART PP 25396
Useable Case Capaci: 61.912 grain H2O = 4.020 cm³
Cartridge O.A.L. L6: 3.340 inch = 84.84 mm
Barrel Length : 23.9 inch = 607.1 mm
Predicted Data for Indicated Charges of the Following Powders...
As I understand it, if you're doing this for OBT purposes just close the bolt on an empty chamber then stick your cleaning rod down the bore and put a mark on the rod right at the muzzle. Measure the rod from the end to the mark, and that's your barrel length.
Okay, that actually gave you a bit more headroom, I think. Here's what QL thinks:
Cartridge : .375 Win.
Bullet : .375, 200, Sierra SPFN 2900
Useable Case Capaci: 40.665 grain H2O = 2.640 cm³
Cartridge O.A.L. L6: 2.560 inch = 65.02 mm
Barrel Length : 20.0 inch = 508.0...
I agree with Scotty wholeheartedly.
I've read through this thread and did not see any mention of an actual water capacity measurement. It can make all the difference in the world. Case in point: that slick new 70 Super Grade I snagged a couple of months ago? My load for the older .280 pushed a...
Right place at the right time, good for you.
I've got one that was made in 1946 and belonged to my dad's brother-in-law who dropped dead at the ripe old age of 39. My dad kept it in a closet with his old Remington 17, and when we had to place him in assisted living they became mine. I think I'd...
I can attest to that, I've held one and did not need to fire it to come to the same conclusion. The freekin cylinder is as big as a frozen orange juice can!
Thought I saw, but didn't...and NOW I see exactly what you're looking at. Strike TWO!
I'll just take the walk to first and make no assumptions. Maybe someone can give a real answer.
I see what you're saying now. I don't have a Nosler manual, but in the online data it appears that they list the very same charges for .223 and 5.56. I would assume that the data is all 55000 psi since they would not list .223 loads above SAAMI pressures.
I have seen other manuals,though, where...
I think I have most of what I want, and way more than I need. I'm still dazzled by the M70 Super Grade in .280 I snagged a few weeks back and just haven't been wanting anything...but I am prone to sudden attack of gottahavititis. One rifle that might induce such an attack is an H&R 317 Ultra in...
There seems to be a lot of conflicting info out there.
I've done a lot of searching and reading on the subject, and based on what I've been exposed to, here are the "facts" pertaining to M192 and M855 ammo:
- if you see NATO specs, pressure is given as 62000 psi
- NATO pressure testing is...
I've been playing with Re17 and 180s in my own .30-06 the last couple of months. I found that 2900 fps is no problem out of my 24-inch barreled M70. I saw the possibility of good accuracy near 2900 and bypassed a node (or what looked like a node) at about 2830. Further testing has shown that the...
If you think about it, a lot of the 6.5s were born in a time when heavier bullets were the norm and faster rates of twist were in their DNA. The opposite is true of the .27s and .25s---look at why the .250-3000 was bequeathed the 87-grain bullet and the rate of twist it received. The popular...
Sometimes they won't be offering what you want when you want it, but a little forethought can go a long ways. I started laying in components back around 2002 or so, with the thought of acquiring a lifetime supply of what i like. Swapping rifles around tends to blow up the scheme, though.
I have...
