Well Marshals articles indicate the really heavy slugs aren't stablized by the 1:38 twist. It would seem I have a 1:38 twist and was thinking of rebarreling. I know Marlin uses 1:20 in some of their guns and it seems to work ok. I have also heard that the faster twist reduces velocity. How much velocity am I going to loose at say 1:25 or 1:18?  Just how much twist is needed for the 350+ weight slugs?

FA18CUB,

Actually, the 1:38 twist will stabilize the heavier bullets fine IF velocities are kept at the top end of the envelope!  I've not really had problems with anything stabilizing except for the .432"-405g WLNGC bullet, and that only at velocities below max possible.  Albeit I have experienced more tack driving accurracy from the 325-330 grain bullet weights.... but you don't need MOA precision with the 405's anyhow.... unless they are some awfully tought prarie dogs!

I wouldn't waste your coin on rebarrelling that gun!  The truth is, that I've had two reported bullets recovered from game when customers were using the .444.  One was from a fellow in Bethel Alaska, and using the .444 in a T/C Contender, and he recovered a .325g WLNGC pill after extensive moose penetration, and the other from an elderly gentleman in Medford, Oregon removed from a 6x7 bull elk after lengthwise penetration by a nose-annealled .432"-325g WLNGC.... the bull was running away when he popped it, and the bullet penetrated full length and rested under the hide of the brisket, the annealled nose expanded to just about the size of a quarter, and stopped expansion where the hard bullet shank remained.

The point of all this?  Once you get over the 300 grain mark in bullet weight, I sincerely doubt that you'll find much in North America that will stop one of these hard-cast pills.  The two incidents described above are the only reports of recovered bullets relayed to us by our customers when using our bullets in the .444 Marlin, in over 11 years of business!  Load that new smokeless pole up with some 325's, 330's or 355's and go hunting!

FWIW!

God Bless,

Marshall

Pac-Nor just called. More expensive then I thought, they said it was a lot of hand work to fit and finish the new barrel to the M-94. The prices are $570 for the new barrel. $700 for a new barrel with a muzzel brake. I guess I will carry my .45-70 Guide Gun when I want more then 355 grs! I hope the Coastal Browns are still impressed with the .444 in 355 gr loading!  <!--emo&;)--><img src="http://beartoothbullets.com/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'><!--endemo-->

Marshall.... that's a TERRIBLE failure rate... only TWO bullets have worked correctly in 11 years?  You know what those gunwriters say, if it doesn't stay in the animal then it doesn't expend all it's energy and the critter will be LOST!!!!!!!!

Wonder what ever happened to the other 99,998 critters that have been shot with your 444 bullets?<!--emo&???--><img src="http://beartoothbullets.com/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'><!--endemo-->  They could start leaping out of people's freezers any minute and cause general mayhem....

One interesting thing about theories & formulae is that about the time you think you have an infallible one, Ma Nature raises up & blows it away.
Hey, if it was all black & white & read all over, what would we have to argue about.
Any how if I can get the file attached , the "Greenhill Formula" is an old one that has been used to estimate required rifling twist.
