    I found that information and was ready to come back and report but phone died if it can handle the 375 H&H it should handle the 404 Jeffery. It would require opening bolt face and extractor slightly. I’m thinking maybe the magazine would need some work but not a whole lot. In my standard 98 I had to widen the magazine.06 on each side if I did it again I would probably copy the original Jeffery trick of using the wood of the stock to make sides of magazine.

    Hoss,
    Yes mate it can handle the .404 easily. I made one on a 602 over 10 years ago and it's still going strong. Other than the bolt face everything else stayed the same.
    My preference would be a standard length 98 modified to fit the .404 though.

    Bos , here is my concept of a dream gun . I dream someday of having a rifle built in the caliber 11.2 × 72 mm Schuler . It's an old German .440 Caliber with a rebated rim which used a 401 grain bullet . I will use 401 grain woodleigh bullets and turned down .404 Jeffery Brass cases and want the gun built on a BRNO ZKK-602 action. Is a BRNO ZKK - 602 action appropriate for the 11.2 Schuler ?

    Hoss,
    I like how people keep these sort of almost obscure calibers alive. The 602 will be just fine, it might be a bit tricky to get it to feed being a rebated rim and all.

    Getting it to feed and extract may be a mission even for a very good gunsmith. The bolt head is also to big and would need welding up, machining and then hardening again. The standard 602 extractor may also be too big for the rebated rim. It might be easier to stick with the original design parameters and use a standard length 98 and make the mods others have made to get the likes of .404's and .416's to feed.

    Whoa ! I didn't see that coming. I'm probably better off finding a vintage rifle in that caliber :(

    Hey Shawn,

    I hope things are going well for you.
    One question I have, is how did you ensure your front sight was perfectly at 12 o'clock?

    I clamped the action to a level table and made a level that clamped to sight to get it level.

    That is far too straight forward!

    Ok finally got some time in behind the 404 and then some time looking at my sights good news is it held a decent group bad news is the group is 9” low at 50 yards. Recalculated my figures and wondering now where I got my original numbers from with Back sight sitting in its highest position I’m almost.200” lower than front sight. Guess it’s back to the drawing board. Going to make a new temp that I can adjust way more than needed until I get her shooting right then I’ll make a permanent sight for a finished rifle.

    Shawn54, how tall is your front sight? I can measure mine if you like?

    Front sight is really tall but my choice of stock require it to be so. When I ordered the stock it was my plan to scope the rifle but then I decided to go with open sights. Most rifles with open sights down low give me trouble lining up (read that large head and no neck).
    Now thinking back I was originally making a blade front sight when I started then I got the Lyman Globe sight after I had made rear sight and did not change back to match. (This forgetfulness is getting worse). Know that the high sights don’t look great but they are right there where they should be when I raise the rifle.

    Shawn, just a thought that may be wrong. The rear sight height will come into play when you shoulder the rifle. Agreed, with no question or reservation. However the front sight doesn't come into play until the muzzle end of the rifle is elevated. Lowering the front sight height will raise your point of impact. If I'm wrong all you have to do is make a new blade. Thoughts / comments? Have you already done this? https://www.brownells.com/aspx/lear...3186&msclkid=22d9cfc1dc0c126d9a299214e8b2c2e3
