    Nothing new under the sun!!

    I had a little chuckle yesterday. I was visiting with some buddies, one was absolutely jacked about his new target rifle. Shilen barrel, Fierce action, custom stock.
    Here's the cartridge:
    Start with virgin 220 Swift brass
    Fireformed to:
    2.35" case length
    0.401" shoulder
    Blown out to 6mm

    Firing a 117gr bullet at 2975fps +/-.

    This ringing any bells with anyone??!!!

    6mm Lee Navy. That's the chuckle part - the 220 Swift was created from the Lee Navy 80ish years ago.

    That's what I was thinking but the velocity and bullet weight threw me off- that's 25-06 territory .......

    You're not wrong! I have an old model 70 in 220 Swift with a shot out barrel. I've always had a hankerin' to rechamber to the Lee Navy just to see what it would do with modern powders and projectiles.

    That would be a good way to bring back that model 70. It would probably fall between the 6mm Creedmoor and .243 Winchester performance wise( that's a little window)

    It seems like Hornady and Nosler introduce a new cartridge weekly.......none that will do the Un- Done, though.

    Well Texas, my boys chose 35wcf, 401wsl, and 25 Remington for spring bear. My wife uses her 32rf for gophers, and I chose 25rf for around the house varmint control..... It's not necessarily about the destination.

    Did someone say 6mm Lee Navy?! Where did he get the 117 grain bullets?

    There was a 6mm Cobra, based on the .220 Swift around during the 50's/60's that pretty much died when the .243 Win/.244 Rem hit the market. Of course the 220 Swift was based on the 6mm Navy but the ^mm Navy has a very long neck and quite a bit of body taper compared to the Swift and Cobra. The 6mm Cobra does show up in some older books on wildcats.

    Easy to shorten a case. Would be interesting to hear how he stretched one an additional .15"

    You use flight line to do that, is my understanding. A little prop wash helps.

    I'm not sure about that? I asked for a fired case for my collection. I'll see him again this next week. I do plan on taking a 236 with me for his amusement!
