High End Intermediate Cartridge Showdown

These are rounds that are basically intermediate between like the 6.5mm Creedmoor and 7.62mm NATO/.308 Winchester in power and performance.

First is the .280 British (7x43mm) designed for the Enfield EM-2 rifle and Taden LMG. Killed off when the .308 was adopted as the 7.62mm NATO

Second is the .276 Pedersen (noted either as 7x51mm or 7x52mm) designed for prototype versions of what would become the M1 Garand and Pedersen semi-auto rifles, but what abandoned when General Douglas MacArthur recommended retaining the .30-06 Springfield.

Third is the 7.35x52mm (also called 7.35x51mm) Carcano developed in the 1930s to replace the 6.5x52mm Carcano, and based on the same shell casing necked up to take a 7.35mm (.298) bullet.

All three rounds have similar ballastic performance, and can be described as high powered intermediate rounds that were much more powerful than say a 5.56mm NATO or 7.62x39mm, but not as powerful as say a .308 Win. or .30-06 class round.

History and specs here for the .280:

.276:

7.35:

Which would be your choice?

As I've been shooting .308 since 1979, I'm not going to change.

The gee-whiz 6mm and 7mm bullets get through the wind just a bit better than 7.62.

Thatís all.

Points are precious in precision shooting games.

For hit/miss events the metric is more pass/fail than 100-6x vs. 98-7x

Basically what I'm looking for is opinions on these rounds vs like say 6.5mm Creedmoor and such, and that a round intermediate between like a .30 Remington/.30-30 Winchester and a .308 Winchester/.30-06 Springfield might be better than most "intermediate" rounds today for most uses.

Thing is, these rounds existed, but mostly as experiments in the end, and only the 7.35 Carcano saw issue, but only in the very early days of Italy's direct involvement in World War II. Most 7.35mm Carcano rifles got issued to second line units, though a lot got sent to Finland and used to an extent as substitute standard issue rifles. However, the Finns favored their Mosin-Nagant adapations, captured Russian Mosin-Nagants and Tokarev SVT-40s.

IMO, all those rounds do represent missed opportunities, as 7.35 Carcano seemed to be pretty effective at most ranges that targets could be accurately engaged with iron sights at the time, and .280 British simply was a short case powerhouse.

For killing, anything 5mm to 12.7mm seems to do the trick if you put it inside the 8-ring.

I've seen whitetail deer killed with 4.5 mm.

The 6.5 Creedmore is the latest flavor of the month cartridge. No telling how long it will stand up to what will come along next.
I think it is an excellent cartridge, but somewhat specialized. It was built as a long range target round for heavy bullets in 6.5mm and a tight target type chambered rifle.
These rifles are already showing up on the used gun rack in my area. No surprise to me in the heavily forested environment where I live. Long range shots here are not the norm.

The 6.5 Creed rifles I'm seeing are all heavy long barreled 12lb affairs.
I like less weight, more portability.
My preference is the Sporter Weight rifles with standard barrels shooting normal weight bullets, a 260 Rem or 7mm/08 is the calibers I would choose.

I don't have either of those, but a 6.5X55 and 7X57 Mauser fills that need adequately. .308 Winchesters and 30-06's are also favorites.

I'd consider a 6.5 Creedmore if it came in Sporter weight configuration and had a twist rate that handled 130~140 grain bullets accurately.

I ordered a 300 BO pistol kit on Valentine's Day.

Palmetto is the love I love to hate.

In an "intermediate" sort of way..

I mean really, who can't love a "handgun" that is accurate to 100 yards.

I makes sense in a doesn't-make-sense sort of way.

Which in this climate makes sense to me.

More shit to move I guess.

Stop making sense!
