IMO, with the available bullets at the time, I don't think it got the best use of its case capacity because there wasn't the heavy for caliber bullets that they have now.
One of the downsides to using large sized cases with some of these smaller bores, is you really need to run barrels that are typically in the 28ish range to get the real performance out of them or they, often, just shoot slightly faster than some of the others with quite a bit less case capacity.
Also, often the accuracy loads are right around the same, give or take 100fps, as the stuff with the smaller cases, too.
I'm a big fan of the 6.5's and I looked into having a 6.5 built off a necked down 338 Lapua case. Talked with Kirby Allen, who loves making things go fast, about it and not even doing an improved shoulder, it still just didn't pencil out, at least with the bullets that are currently available, it didn't. Now, if Berger ever made a 180gr Hybrid 6.5 that could possible change things. :tup:

I get 3147 out of a 6.5x284 pushing 140 vlds. That 300 must be wicked fast one in 7 or 8 twist.?
And I think Travis w/RBros gets right at 3200fps out of the 140's with the 26in barrel 6.5-06 Ack Imp he builds. My dad has a 6.5-06AI that is long throated for the Berger 140's, not built by RBros, and he gets just under 3250 with Travis's Retumbo load but his also has a 28in tube, too.
I think I read they are getting just under 3400 fps with 140's in the 6.5-300Wby and 200fps is certainly nothing to sneeze at but it's also doing it with a case that has 30% more case capacity than a 6.5-06 AI, too. That's a huge increase in capacity for only 200fps.
I would have thought they learned something with the 30-378 but guess not.

Pretty much my thoughts, still a wicked round but for a working wage I make no way. Those 6.5-06 are pretty sweet rifles, just had a rifle built two years ago and it was between that and the traditional .280 Ackley which ended up what I had built.

What do you get out of the .280 Ackley?

Thats almost 300 fps faster than I'm getting :yike: what powder charge are you running? I do only have a 24 inch barrel, but still

With 140 berger haven't ran a load up to hot but accuracy wise its at the 3200 mark. 162 Amax chrono'ed about 3080 and my 168 Bergers are a little slower at 2850..I get 3147 out of a 6.5x284 pushing 140 vlds. That 300 must be wicked fast one in 7 or 8 twist.?

thirty inch pipe , with 52.5 grains of rl19 (i believe but i will check the powder ) 300 of the lands . ran 60 lappers through it on break in . thing clover leafs at 200.I get 3147 out of a 6.5x284 pushing 140 vlds. That 300 must be wicked fast one in 7 or 8 twist.?

How long of a tube are you running to get 3000 fps out of 160's? Mine likes 140 AB's pushed by a full dose of H4350 but It's only doing 3100 according to my chrono out of a 24" lilja.

25 inch bartlein pipe carbon wrapped with seekins brake. Using a pretty stiff load of h4831sc. The chrono'ed velocity is correct on the 162s but haven't shot at distance to see if the 140s velocity matches the dope chart yet

Everyone should have a Vectronix! Otherwise you're stuck shooting short range, like 1500 yards. :chuckle:

Yeah, sure, rub it in why don't you. :) You were one of the smart ones that bought a Terrapin, which is easily the best and most affordable range finder with capabilities to accurately range wellllll past 2000 meters, before Vectronix stopped making them. I'd reallllly like to say I did the same but I can't because I didn't. :bash:

The bullet choices then weren't as good as now as they had problems with the long range bullets not expanding.

That was dumb luck that I timed it so well!
Somebody needs to get the new Weatherby and then see how fast the 160 matrix bullet can go out of it.
