Improving the 308 Win performance

[Farmerbrown32]

I improved mine by sticking a 215 hybrid in it. Getting 2425 fps out of a 16" tube in my dt covert a2

LOL looks like someone talked stuff to the wrong person LOL!

Nah- just have other things happening in life and don't have all day to follow up on every comment. And obviously struck a nerve with a bunch of fudds for having the audacity to question their obsession with a seventy year old machine gun cartridge, so was going to give them a break before getting reported to admins for veering too far off the main topic of the thread.

Your fuddery is probably due to your ignorance of not knowing the shooting disciplines (F-TR).
Not talking about hunting here...Most guys who are mentioning a 30" 308 are probably using it for F-Class comps.
F-TR only allows 2 cartridges to be used...223 Remington and the 308 Winchester. For 600 and under the 223 is used quite often for obvious reasons. Most use the 308 for 6-1K though.
They are heavy rifles, but they cannot weigh much over 18 pounds, including the Bi-Pod. You cannot use a front rest.

I'm familiar with F-Class (non-open). I find it to be a bit archaic, like shooting a longbow. I assumed this was focused on hunting, where you don't have arbitrary limitations requiring you to use specific casings.

Elk at 900 with a 308 is a crap shoot. Idc what load.

and that is what pings your snake oil detector...

Looks like things have changed quite a bit since I hunted in Texas.

One of my Fuddery 3-O-Wait's
Since you were not pleased with 30 inch 308 Winchester's, here's my sub 16 inch.
Last spring while I was doing drop confirmations. The steel on the left is 10 inch, and yes that's my first shot at 500 yards.
Impact velocity is 1764 ft./s at 500 yards. That makes this little, specialty pistol (Remington XP-100) capable to kill cleanly with the bullet I am using just shy of 500 yards. Not bad for a 3-O-Late

Dan was doing some load development, getting ready for the Southwest nationals a few years ago. Sebastian was going to be shooting and we were changing bullets. This is a five shot group at 600 yards. Those are 1 inch squares. On one of the shots, Dan called that he made a bad touch on the trigger at the shot.

This is what foolhardy fuddery looks like at 600 yards. Four shots right at an inch at 600 yards, then the pulled shot, still makes it a fairly decent group. Add to that, it was 14° below zero not counting the windchill when he was doing this, so this is what foolhardy fuddery looks like at 600 yards. Four shots right at an inch at 600 yards, then with the pulled shot, still makes it a fairly decent group. Add to that, it was 14° below zero not counting the windchill, when he was doing this, so I might be willing to give Dan a break for not having a perfect trigger squeeze each time.
Dan even dressed up for the occasion

That's some impressive shooting, no doubt. My questions/critiques on .3sl0w8 aren't related to accuracy. We've had 6PPC, Shehane, etc. putting single holes in paper for a very long time and modern machining seems to have proven that you can build a custom rifle to cover up shortcomings in virtually any cartridge (example: .300WinMag free bore).

I am glad you are familiar with F-Class...Different strokes for different folks.
What some people consider archaic, is another person's passion-Either is fine with me.
Do people intentionally build a LR hunting rig, with fixed position shooting in mind? You bet they do!
Would a heavy rifle with a 30" 308 Win work quite well for that? Yes, depending on the max distance they intend to kill at. Are there better cartridge in my opinion? Yes.
The thinking that just because a cartridge had a original design purpose(s), it is not capable of other things is a interesting mindset.
Personally, I have never considered the 308 to be a LR hunting cartridge for big game for my uses. For me it is a mid-range hunting cartridge 600-700 yards. Can it go and kill pretty good further out? Seems to be some evidence for that with some specific set-ups.
I typically go with a larger 7mm case, if I want to stretch things out (Including elk in this picture).
Would I use a big 6.5 case or 30 cal cartridge? Sure.

Agree with distance here Ernie. We've killed 5 Whitetail bucks at 3500' elevation and over 500 yards with the 308 and 24" barrel, longest was shot by my father when he was 76, 691 yards and DRT. 168 Amax over 45 grains of Varget and Lapua SRP brass. High shoulder shot dropped that buck after 2 steps. He never knew what hit him.

Would I shoot an Elk at 691 with it, NOPE. Would I at 400-500, probably if all the conditions were there.

Cfe 223. And it shoots sub half. Will shoot one hole if u do ur part.

Solid numbers there.

The Amax popped into my mind. Frangible round would have better odds with terminal performance at long distance.

Nice.

If the Elk's not moving and you're a god with math, lean on em!!
