A new cartridge.

[Bill]

Yeah just imagine if we only had access to 303 s and 310 cadets.......

[Gamerancher]

Hell no! I think I'd give up shooting if they were the only options.
There are a bunch of great cartridges available based on the .222 head size.
I personally have .221 Fireball, .222, 5.6 x 50 magnum, and .300 Whisper.
Next project will be a .25/222 as a culling rifle. Just because I like my "1/4" bores and I have a bunch of 222 cases and .25 cal pills.
I also shot a .300 Apache ( .30/222 ) last year in the U.S, nice little round, knocked down 500m silhouette rams, so better retained energy than .243Win at that distance. Can't remember what the load was, but the son of the bloke who came up with the round wanted me to have a few shots out of his rifle.

A rimless straight walled case will have to heads pace on the case mouth - much like the 45acp - I can see problems making it from .223 cases - stretched to 357 cal the brass will be a bit thin to offer much to head space on. Like it has been said before it is so close to a rimless 357 maxi that there would be very little, if any difference,in terminal performance. The maxi is a case crying out for a lever gun to live in and it already has a home in single shot firearms, to wit the Thompson Center "Contender" carbine and pistol. I have barrels for both and and with the right loads they are great for slamming both steel rams (metallic silhouette) and the real thing (pigs,goats, deer) Sounds to me like another "come in sucker" marketing exercise by a major player in the firearms industry but I guess time will tell.
To see how good the 357 maxi is read the info at http://357maximum.net/

Gamerancher - you should check out the "Myra'" range of cartridges - all based on the .222 - developed in the late 1950"s by Broken Hill gunsmith Arthur Langsford
There was a 243 Myra, a 250 Myra, a 270Myra and a 300 Myra

GAME CHANGER!!

GAME CHANGER!!

[Gamerancher]

Yeah Ramslamer, I know about the Myra cartridges. Like most "new" cases that hit the market, it 'aint long before folks start necking them up and down.
Langsford was just doing what 100's of others around the world were doing with the case. He just never submitted them to SAAMI, so they go in the pile with all other blokes "wildcats".
Another very efficient case that has the same sort of history is the 250 Savage. It has been a favorite case of wildcatters since its release in 1915. The most popular of which was the necked down to .22 cal version that went on to be standardized by Remington and released as the .22-250, I couldn't count the number of devotees of that cartridge that are totally ignorant of that fact.

Especially for higher performance loads, what are the know issues with cartridges headspacing off the mouth? This is a question for any of you knowledgeable peeps actually..

Might make for some fun in a revolver

Having a bit of a quandary moment..

Have a Wedgetail WT 15 and am looking to make it more flexible by adding another upper.

Mainly used in timbered country in NT. Probably 300 meters max.

Looking at 350 legend over the usual offenders, being 300blk and 6.5 Grendel

Any thoughts?

[lister50]

Ask me in a week when I pick up mine

Was looking at another .308 as my son is joining me hunting deer in high country, and I just purchased a .350 Ruger American ranch carbine today.

I love the flexibility of the .308, but I wanted something in the smaller footprint, and I stalk on foot. I'm not into the long range gig or shooting hilltop to hilltop, so I think it's A great middle ground.

But the proof of the pudding as they say...

Looking at 350 legend

See if you can get an upper for 450 Bushmaster.

Good solid round, same OAL as the 223, takes readily available 45 cal projctiles, fair bit more punch than the re-invented 35 Remington.
