Re-Barreling a Shilo

[Kurt]

Well Steve that Mega Mite is a brute for sure. Heck the handle is heavy enough. Just let it fall and it will get the job done. LOL
If you want to get the core right on the money with weight give it enough time to fully bleed out or pump the handle a couple timed and it will drop out right on.

I have equipment from both Corbins, Dave and Richard.

I just got an E-Mail from CPA letting me know that my Second .38-50 is done. so work will begin all over again.

OH! Will it ever end???????

Guys,
What’s the formula for bullet length?
Jim K gave me a mold and said “try this”. It worked! But according to what you’re saying, it’s too long for my 18 twist barrels at 1.435”.

That length will work right up to the time you start crowding 15 minutes windage. Then you'll start getting a ton of vertical. 1.4 keeps you in the safety zone.

Don, My bullet is in the 1.4" realm. With a 45-70 I think to shoot the best a faster twist is needed due to the slower speeds. I know 18 can get it done but, I am always looking to get it done better. lol. I think under stabilization is a bigger concern than under. A faster spin actually increase the bullets BC so it will fly even better. Brian Litz (The Chief Ballistician for Berger Bullets ) has a set off books out call Applied Ballistics (Also has a company by the same name). The books are very informative and he carries out tests to prove or disprove "what we know". He uses a Savage rifle with multiple barrels from both the same and different manufactures, varying twist rates. Really in depth testing. He ever tests chronographs. News flash on that one. Anyone of the current Laradar, Magnetospeed and Ohlers(sp?) are so close the difference is in consequential. His personal Chonograph has a ten foot sky screen spacing for the best/most accurate readings. Most of his stuff applies to the passing fad powders (smokeless), but some of the info does cross over to our stuff.

Kurt, We had been using pure lead bullets until recently. He read Perry's book and came to agree with me that some tin should be added. We are now using 1-16 which he found easier to get the weight spot on with. I told him it would have a more consistent flow of metal, plus it is nicer to cast. Congrats on the new rifle, a CPA is on my things to do list.

Steve I shoot a 16 twist 45-90, and the only real difference between the 525 .446 money bullet and the 535 is the 535 holds up a bit better when the winds above the flags are kicking around a bit.
16-1 is the alloy to go with greaser or patched when shooting long range
