The barrel for my 458x2" XP has shipped! Guess I get the other projects done so it can have its turn!

Aaron

Aaron what brand of barrel are you using? Contoured blank?

Jon

Aaron,

when you get it completed please post your range results. I have looked at this cartridge as a straight wall case option for the XP and am very interested in your results.

Thanks
Dave

This barrel is a McGowen. I like their blanks for SP builds. It is a #8 contour. Once I get it together I'll post pictures and range results


Aaron

Lots of neat bullets for that one....
Matt

A really cool round. I shot JD's XP in 1979 while visiting him. Did iron targets out to 200 yds. fairly easy. He had a iron mastodon at 500 yds. Even got it after a few shots. A proper break and stock make it reasonable to shoot, but it does get your attention.
I don't think it will be a proper mtn. goat round!

Should be a good bear hammer

Now I remember I was supposed to dig out a reamer for you

Planning on using it for bear. Should hit em hard.

Aaron

I believe BLASERMAN has one. Hopefully he'll see this and chime in.

Can anyone tell me what the difference is between the 458x2” and the 450 Marlin is ballisticaly? I know the belt on the Marlin is longer and I guess the case on the Marlin is .100 longer but other than that arn’t they basically the same? If that is the case is there a reason to pick one over the other?

Dave

When you're ready, I'll send you all the load data I collected for mine. 300's and 350's aren't bad, 400's start to get your attention.

I'll take you up on that! I've got a bunch of cast bullets in the 300gr weight range and some 400gr x's.

I picked the 458x2" because I found a cheap reamer. A buddy gave me a bunch of 458 brass and bullets. One reason to choose the 458 vs 450 is that any of the belted mag brass can be cut down and used. IF hornady were to quit making brass for the 450 you'd be up a creek.

One reason to pick the 450 is that a 458x2" supposedly could be chambered in a 300mag or 7mm mag. Wouldn't be good if the trigger were pulled then! I don't have a 7mm mag or 300 mag to see if one will fit in it.

Aaron

I was told the 450 Marlin dies could be used for the 458x2. This was AFTER I passed up a model 7 in 458x2.

I spent some time looking at the prints for both cartridges before deciding to buy 450 marlin dies. I'm pretty confident they'll work ok. May need a didn't crimp die though.


Aaron

Aaron did you move your lathe to AK or does someone up there have one you can use? Did you feel that earthquake where you are at.

Jon

He moved the Lathe up there and he drug the mill up there too, even though he didnt want to take the mill.

Didn't feel the quake. We're a long ways from the center of it. Have a buddy who was right in it.

I did move the tools. Pretty darn spendy getting them here. There aren't many on the island so I doubt I could borrow one.

Thought you might have left them with Adam for safe keeping.

Jon

He made it clear he doesn't have the patience for it..... It would have made the move a lot better!

Aaron

What length barrel did you decide on?

It's 18" right now. I think I'm gonna cut it to 14" plus the brake.

Aaron

In for the build.... Love the big 45's in SP's.... I know U gonna rock it from start to finish...

Got the barrel in. Just gotta clear the slate first before I start on this one.

Aaron

Finally sent the data, should be 10 pages, enjoy!
Rog

Thanks!

Aaron

Look at some of the last few builds on here and give those smiths a call, send a message to the owners and ask about the overall service and work done. We have a lot of talented gunsmiths on this sight.

Glenn

Like I said above, I shot JD's personal .458X2 XP years ago. Excellent gun. Might want to check with SSK.

OK where we at on this project?
