Home Forums Hunting & Shooting Hunting Rifles .270

Why is it 270 bullets on average have lower BC's than 6.5 or 7mm? I know 270s are traditionally twisted slower but even when bullets seem proportionally similar and of similar design the 6.5s and 7mms tend to have better BCs. Compare say a berger 6.5 140g vld to a berger 270 150g vld and then to a 7mm 168 vld.

Even on nosler able bullets the 270 bcs seem to be a little lower proportionally. The 168g 7mm and the 165 270 are about the same but I'd guess the 175g 7mm is proportionally more in line with the 175g 7mm.

At least there are finally some heavier higher bc 270 bullets available these days. It just seems that if bullets were designed the same and sized proportion to their diameters there should be much difference in bc.

I always wonder why the military keeps leaning towards .277 or 6.8 when there seems to be better options at 6.5 and 7mm. Maybe mathman has the answer. What weight would a 270 bullet be if it was built proportional to a 140g 6.5mm?

Besides the perceived advantage I've had for 6.5 and 7mms the main reason I've never been a 270 guy is much more primal. Growing up my step brother and his uncle both shot 270s and would never stop talking about how much better they were than anything else. And my step brother was such a douche in general I could almost always bet that if it was his favorite it wasn't the best.

They always gave me a hard time for shooting a 6mm. One day when i was 14 or so the uncle emptied his mag at a doe across a canyon, reloaded and was on about his 8 th shot as I came over the hill and saw the deer. I sat down, put my elbows on knees, elevated my little 2-7 vxII about 2 feet over the deers back and dropped the deer he'd been shooting at with my first round.

He was so pissed he never took me hunting with them again. I ironically was the only one with a tag and didn't want him shooting my deer so of course I shot at "his deer". All the way home he was swearing and huffing and puffing. I just kept saying worrying, I figured if a 270 couldn't drop one at that far there's no way my little 6mm could.

It was years before I'd consider owning a 270. I've had a few now and then and some shot quite well. In actuality the cartridge that is becoming my favorite all around big game round these days is a plain old 280 which is so close to a 270. I'm currently using some 280 AIs and a 7 prc but I'm planning an ultimate last rifle and I'm leaning hard towards an 8 twist light sporter 22" plain 280 on a rem or clone. I've been eyeballing a kelbly nanook and wondering if brux will do a 22" #2 in 7mm.

I tried to do my ultimate traveling rifle in 30-06 a few years back. It never shot quite like I wanted but I loved the way it fed and functioned and stacked in a rem mag box. I still regret selling my stainless 700 KS 280.

Had the .280/7mm Express been factory loaded to 65K, probably would have settled on the 160 gr. in that cartridge and never looked back.

That said, the .270/150 gr. has been outstanding.

Rather have my 308's.

Never a .270 fan. Never will be.

The .308's strong suit was to produce M2 ball ballistics in an automatic rifle.

Take that 150 gr. ball round, at that same velocity, and give it the Sectional Density and Ballistic Coefficient of a 180 gr. .308, in a hunting bullet?

You get the .270 Winchester.

Out to 400 yards... it is still one of (if not the) Best in the field.

The .270 Winchester is one of those cartridges where today I probably would not go out and build a custom rifle for it. No need, I already have an exceptional Ruger #1B in the same, and it is very, very accurate. More than once put 3 in the same hole at 100 yards. Think it's 8 for 8 on bang flops for deer & hogs. It also has really nice wood, and is semi-collectible being made in 1976. Obviously, this is one of the ones that got an exceptional barrel, and if I found another one close to the same serial number range, I'd grab it without hesitation.

On the bucket list for it is trying 130s with Reloader 26 - which some have discouraged. With the Ruger's 26" barrel I have seen 130's go in the high 3100s, with Reloader 22. Work up, these are not light loads.

It probably would be the last centerfire rifle I'd sell.

Yes, the 6.5CM ammo is usually available here if any of my other picks are. I didn't list it because I'm not sure if that will be the case 10 years for now and the other 3 have that extra track record.

I do load my own ammo, but it is still handy to be able to pick up some ammo sometimes without loading it. I tend to horde my components to make my most accurate loads. I don't need the most accurate loads every time I go hunting or shooting. No need to load if the corn pile is only 80 yards away and your longest possible shot is under 100 yards.

Isn't that 'tard on the left the one that Bogart'd the trophy Mulie last year from some young lady in Utah and then lost his job over it?

No. That's his brother. I guess they're twins

Won't disagree. However, pair the 308 with the 155 Scenar and you have a lightning bolt in your hands.

Ha, ha, that is a great joke.
