All things .308 Win

I can show you plenty of not very good groups from multiple 308 barrels. I can show you plenty of excellent groups across multiple powder charges from cartridges other than 308. While I don't dispute that those groups you showed are extremely precise, and your experience may be that your 308s do this and your other cartridges do not, your groups do not prove that 308 is somehow more inherently accurate/stable/less finnicky than other cartridges.
Until another of my chamberings does what I have shown some of my .308 barrels will do, I will continue to believe they are more eager to please than the other chamberings I shoot or have shot. What other chamberings of yours have done as well?

Got it. Pumping up the 6CM in the 308 thread allows 1/3 to equal damn near half. Made up numbers is all I was sayin’. And you confirmed with your very own spreadsheet.
Oh boy, good job, you got me. So it's only 1/2 the recoil for better ballistics from a shorter barrel. Owned!

I've found it really has more to do with the barrel than the cartridge, personally. Better barrels shoot everything better.

Simply called you out as a person who was using exaggerated numbers to bolster their point. You no longer deny that. And your amended position of 1/2, better, shorter checks out. Glad we got that sorted.
 
At the risk of reigniting the dumpster fire: Can do everything better? Incorrect, the 30-06 can't fit in an 84M action. Have had a couple of 84Ls in 30-06, but they're just not the rifle the 84M is and went down the road.
That is true but that half inch of action length, so pesky.
 
Let's get this thread back on track.

This is a 130ttsx recovered from a whitetail buck that a friend of mine shot with my 308. MV is 3100ish and shot was sub 80 yards. Surprised that I found the bullet. Small sample size but ive been happy with this bullet so far.

Man that thing is flat. Guess that's what 3k fps will do. What did the wounds look like?

Not to derail but would you please add this to :


Thanks!

What was the angle of the buck and shot?
 
I’ve long felt 308 is the most boring cartridge in the world. Capable but dull as dishwater. And that it’s only real home was in a battle rifle.

Then when I moved here I knew instead of having a safe full of options I likely need to make one rifle work for all my hunting for at least the next few years. I also would need to pay better attention to logistics because I wasn’t going to be able to load up the peculiar metric calibres that I liked for no other reason than I liked them. I’m unlikely to ever get a shot past 300yards and shots at 50 are a lot more common than shots at 200. Coupled with a lead ban for hunting coming in a few years. It was impossible to make a logical argument against 308.

As mentioned earlier barrel lasts forever. All my local shops have a variety of ammo options. And it will kill everything from a muntjac to a red stag with most of the ammo on the shelves

At least the rifles pretty.

The 43 and 43.3gr charges were still too hot, producing sticky bolt lift. The 43gr group wasn’t too bad at .999”, and with the 43.3gr charge, eight of the ten went into .538”, but two “flyers” opened the group to 1.423”. Had 15 rounds of prepped brass left in that box, so loaded up five rounds of 42.4gr and 10 rounds of 42.7gr. I wasn’t impressed with how the 174s were grouping thus far, so also loaded up some 168gr Tipped Matchkings, which my hunting rifle really likes, and for a 168, has a really good BC with a .535 G1. For the TMKs, I was more cautious and loaded up ten charges, .2gr between charges, starting with 42.7gr and ending with 44.5gr, the charge my hunting rifle likes. These were just to find max, to give me something to work around. Before this range session, I wasn’t happy with how I mounted the scope due to reticle cant, so remounted it, this time to my satisfaction. This range session, I started with the TMKs, using the first charge as a sighter then made all the adjustment my zero stop would allow before grouping the next nine. The next nine of 9 different charges went into .495”, though by 43.7gr, bolt lift was getting sticky again. I then fired the ELD-VTs. These grouped better than heavier charges, but nowhere near as good as the TMKs did. This rifle definitely prefers the 168gr Tipped Matchking over the 174gr ELD-VT and once I finish up with this box of 174s, I’ll not be pursuing them further.

So I got to thinking about this series of test and thought that I should not be getting heavy bolt lift with the charges I tried. I wondered if the bolt handle timing was off on the Solus and was not getting the primary extraction I should from it. So, I called Jon Beanland and talked to him about it. Told him the bolt would open easily part way then take quite a bit of effort to open the rest of the way, but no other obvious pressure signs. Primers were good and no ejector swipes. Jon asked me if I was using new brass and the light came on. I had had this happen once before when firing resized brass from another chamber in a new chamber. Sometimes a standard sizing die won’t squeeze down brass fired in another chamber far enough on the case walls to provide enough clearance for proper expansion, resulting in sticky extraction. I immediately went to the garage and resized three rounds with my small base body die, took them out back and fired them into the ground for a function check. Eureka! No sticky extraction. Now that I have sized that brass with a small base die and fired it in the new chamber, sizing with a standard die will be sufficient. Lesson learned…. Again…
