Is the .300 Savage the 7.62mm Creedmoor?

Similar to the logic of the 6.5mm Creedmoor, the .300 Savage or 7.62mm Creedmoor, allows long-length, high-BC projectiles to be loaded successfully while still maintaining the OAL requirements for 7.62mm NATO or .308 Winchester platforms. Advanced powders allow for full-velocity levels to be achieved.

True or not true?
 
If you want over-max length 30 caliber bullets in a 308 action, the 1.60 case length 300 Herrett is the way to go. It is a rimless version of the 30 Herrett, designed for the XP100 pistol.

Leave the classic 30 cal progenitor 300Savage as a classic! Though some wider ammo selection in normal times could stand to be boosted a bit.

Creedmoor this creedmoor that... Phooey! Lol

I believe you're looking for the .300 sav ai.
 
I've got a Savage Model 99 with a walnut stock, in 300 Savage, made about 1939/40, it hasn't been shot very much, and is extremely accurate with my handloads, however it isn't a Creedmoor, by any stretch of the imagination. Regardless of the projectile used, or the powder. It is however, a great woods rifle.
 
Creedmoor type rounds in general merely try to duplicate muzzle ballistics of an existing cartridge but magnify down range ballistics with heavy, long, high ballistic coefficient, and high sectional density bullets. This requires a new chamber design with a longer throat at least just to chamber such a round. Then, faster rifling must be specified to stabilize the longer bullets. Maybe then, tweak the cartridge case geometry slightly to burn powder more efficiently or some other whitchcraft. This necessitates a different rifle, or rebarrel an existing action to the new chamber/cartridge design and faster twist rifling.

Throw in some marketing to sell rifles and ammo and viola, nearly reinventing the wheel but adding a little bit of intrigue in the process.
 
No.

The 6.5 CM shoots 140-150 gr bullets with BC's in the mid .650's to low .700's to about 2700-2800 fps. To get a 30 caliber bullet with BC's that high you have to go to 210-225 gr bullets. And to shoot them to usable speeds requires one of the 30 caliber magnums. You can shoot those bullets in 300 Savage, 308, or even 30-06, but not fast enough to be much good.

If you start looking at trajectories bullets with similar BC's leaving the muzzle at similar speeds have similar trajectories. And similar penetration if used on game. There isn't anything magical about that, you can get that performance with any caliber. But anything smaller than 6.5MM and bullet weight becomes a little bit of an issue. Anything larger than 6.5mm and recoil becomes a factor to get enough usable speed. The 7mm's are a possibility, but to get a 175 gr bullet with similar BC"s to 2800 fps will require a magnum cartridge.

and all of a sudden, 6.5x55 Swedish became a frickin joke to people.

Nothing at all wrong with the 6.5X55 if you're a hand loader shooting a custom rifle. The advantage the 6.5 CM offers is factory ammo and off the shelf rifles at reasonable prices. The 6.5X55 was introduced in 1891 and designed to shoot 160 gr military ball ammo, not modern bullets at todays pressures.

30 herrett is based on the smaller diameter and thinner 30/30 case. There is one pictured in my profile pic next to a 357 herrett. Fun cartridge but is a big step down in power compared to a 300 savage or 30 TC. It can also be made in a rimless version using 30 remington or 6.8spc brass.

Read closer! I was referring to the 300 Herrett, based on the 308 case, made for the XP-100. Not the 30H. I own both the 30 and 357 Herretts. They shine in 8-10" barrels but are overpassed in a full length rifle by the 30-30 and 35 Rem respectively.
 
well...I've heard of many oddballs...not a 300 Herrett...I've heard of 308x1.5 Barnes, 7.62 Micro Whisper, 7.63 Mini Whisper and a few others...I have to admit that it does sound intriguing...if they made it similar to the dimensions of the 30 Remington that was designed for the Model 14 with a .422 dia rim...you could do something interesting with it...or have they? Heck they did...6.8 SPC and 224 Valkyrie...Remington tried to do a 30 Remington AR but it was based on a 284 Win case...throwing a 125 gr bullet down range at 2800 fps...the old 30 Remington was doing a 150 at 2500 fps advertised...

hmm...I think...a 30 WCF with the Ackley treatment...OR...even better...finding a nice 309 JDJ in an Encore would be even more fun.

Gotta love wildcats :)
 
I don't see a need to re-invent something that already exist. You already have the 308. I always wondered what the big deal is about the 6.5 PRC when we have the 6.5 Rem Mag and the 264 Win Mag. Same ballistics, just a shorter case. Just need to headspace the mags on the shoulder and not the belt. I don't buy into the shorter, stiffer action claim.
 
My LR and PR shooting friend says the .284 Win, either stock or as improved as you can get an already efficient shape, is a strong contender vs the cute little 6.X mms.
