PacNor and Mcgowen makes 8 twist 270 caliber barrels.I would consider the 270 AI or 270 Sherman now simply because of the new 170 gr. Berger EOL, but it takes a 1/8" twist in a custom barrel to make it work. The 257 and 270 bullets haven't received much development in a high B.C. configuration until recently. I doubt it will crimp the sales of 7mm bullets, barrels etc. just by the market presence of everything 7mm.
I typed up a response to this that was a bit condescending, so I just wiped it out and decided to be grown up. Like i said, That's how I feel about this issue. I still don't see the need to create some wildcat that is basically the same as something already available......but if that floats your boat....don't let me be the one pulling the plug on it. I see arguing over which is better, 300 wm 300 rum 300 Weatherby 300 wsm and the list goes on every other post. From what I see here.....Whatever you have is the best and everyone else is an idiot for even thinking of owning one of the others. I am not looking for a fight over this. It doesn't mean that much to me. I think the 300 rum is a good round. It's just not for me. Same as many of the other latest and greatest....ie 6.5 creedThen let's all return to black powder cartridges. Speed is what allows bullets to drop and drift less and carry more energy at extended ranges. Given the same bullet design and BC, I'll take a 300RUM over a 300 Savage any day in elk country.
After all, it is the constant quest for improved performance that brought us out of the black powder era and into LRH and beyond.
The P51 was a great plane for 1944, but how many would pilot it against today's jets?
Why a .280 when you run faster with a .270Why no love? Because why build a .270, when you could build a .280?
Because you have at least 5x the bullet selection with a 7mm than you do with a .270... Not to mention the greater ballistic coefficients.Why a .280 when you run faster with a .270

For LR those would be the picks, but we'd need them in the 160-175gr to really compete with the 7mm selection. And if Matrix isn't shipping to the US that leaves one bullet IMO, the 170gr EOL. That was my issue with going with the 270 AI. So IMO the reason to go with a 270 is the known bullet performance on game. There are hunters who have experience and trust their track record with the 270 Win on big game. So in that sense a 270 AI makes perfect sense IMO. They can gain some more velocity and cut down on trimming brass.What are those most commonly used LR bullets? Bergers? NAB/LR? ELDX/M?
