    Sounds good from a 12.5" Barrel.

    Here is a bit of data for CFE BLK. All rounds fired from 1X7 twist 12.5in barrel 10ft from chrono. Five rounds of each fired for data.

    Mixed headstamp brass. S&B small rifle primer.

    150gr Federal Fusion. 9.8gr CFE BLK

    150gr round at 1050 fps = 367ft lbs


    Round is equal to a 9mm. Gutless at that velocity.

    No doubt. But nice and quiet.

    ya I don't see the attraction here..id rather have a 300 blk out..

    But for screwing around sure..

    I see the mdws guy has that other new one out. 6mm mongoose I believe shortened slightly and necked for .243 bullets..interesting and looks better for hunting..

    That's what I'm doing. Just screwing around. Playing with something a little different.

    For a dedicated suppressed gun and/or something that's to be used exclusively with subsonic I would think the 300 Blackout is the better choice. There are any number of 180-240 grain choices for bullets. The down side is these bullets are generally pretty darned expensive and, depending on which bullet you choose, rarely on sale. For comparison I just bought 1,500 pulled .277cal 150 grain round nose for nine cents each. Combined with less than 10gr of gunpowder that's some cheap shooting right there!

    Anyway, the 277's best use is probably with supersonic ammo. A 90gr Speer Gold Dot or Nosler bonded cruising along at around 2,400 fps from a 12" barrel ain't too shabby.

    A new article in Handloader Magazine by Richard Mann. The article starts on page thirty-two.

    Mad Dog Weapons has convinced Starline to make properly headstamped 277WLV brass. If the info on the MDWS forum is correct this brass should be available in three or four months. It should be 30-40 cents per case.

    Also, MDWS was able to convince Speer to sell the 90gr Gold Dot to JB's Firearms for use in commercially loaded ammo. Hopefully this will eventually lead to new (not pulldown) Gold Dot for the general public.

    Here's a bit of an update.

    I took the Wolverine to the 200 yard range this morning and put it on paper after getting it dialed in good at 100 yards.

    With 23.2gr of CFE BLK and a 90gr TNT I'm printing about an inch and a half high at 100. My thinking here is that should put me more or less dead on at 200 and about 12in low at 300. That's my hope anyway.

    So here is my 200 yard target with the 90gr load. This is two different groups of three rounds each. I fired the first three then walked down to check the target. I then fired another three rounds for a total of six.
