    MIHEC 432640 Lyman Devastator RERUN

    Greetings Casting Brethren,

    I am on a quest to find a true cast, coat, size and shoot Plain Base 44 magnum bullet that shoots a true 1.5 inch 100 yard group from a rifle with H110, Lil Gun or 300 MP at 1600-1700 FPS and light enough to be pushed close to 1000 with HS6 or Unique in a 4 inch Smith.

    At the moment my most accurate load is a 280 WFN that can cloverleaf at 75 yards but turns into 2 inches and rip the ten ring out at 100 yards. I want a slightly lighter and faster load.

    Would anyone else be interested in a 432640 Lyman Devastator in the 260-270 range as a solid and a 240-250 as a HP? Seems to be near the specs of the 2011 run.

    Thanks,

    Phaesler,

    You old guys had it figured out. Us new guys come late to the party want out molds immediately. This buy took over a year to complete.

    Do you still have your mold? How does it shoot?

    While I like my Mihec 434640 in my Marlin 1894 I doubt it will shoot into 1 1/2" at 100 yards... at least from my Marlin. It is a terrific boolit though and of course a terrific mould as are all Mihec moulds.

    And not to deter you but there is a group buy on right now for a Mihec 250 gr. WFN that might fill the bill for you:

    LB,

    What load are you shooting in your Marlin?

    I have had excellent 50-75yd performance, bang flop, and sub 1" groups, good load of 2400 and let if fly. I wouldn't expect cloverleafs from any straight wall pistol case at 100yds.
    The Mihec style was nice, but the NOE run was better feeding IMO.

    I'd have to look it up. I generally use IMR4227 as it is useful other cartridges I've loaded as well.

    I can't recall the charge gr. weight I used for the 270 gr. Mihec 434640 but it will be 20+ grs. I know that 24 grs. of IMR4227 under a 245 gr. boolit is a fairly warm load.

    I did some comparison shooting for accuracy using the Mihec H&G #503 (258 gr.) and the Mihec 434640. The H&G #503 clone was slightly more accurate in that test but not by a lot. it would take a better shooter and more controlled testing to be sure though.

    I had wanted to use 300 gr. boolits in the Marlin but found that the styles I tried did not stabilize from my 1:38" twist barrel. They shot reasonably well to 50 yards but much beyond accuracy fell apart badly with some keyholing at 100 yards.

    265/270 gr. seems to be about the longest boolit I've had long range success with... not that the Marlin in .44 mag is a long range gun in the true sense. I've settled on the Mihec 434640 as my heavy boolit.

    If I didn't have so many moulds for the .44 now I'd be tempted to get one of those Mihec WFN moulds though!

    I’d be down for a 434–640 4 cavity plain base. The two cav I have is getting tired.

    Something you might want to consider is velocity and rifling twist if you go as heavy as 280 grs.

    It just occurred to me that I have not tried downloading those Mihec 434640's. They have been at or near max loads every time I have shot them and so were all the boolits I tried all the way to 300 grs.

    Your story is similar to mine in that I had decent accuracy to 50 yards but by 100 yards heavy boolits were keyholing. I had made an adjustable weight mould so reduced weight from 300 grs. down about 10 grains at a time until I got stable boolits out to 200 yards. 265/270 grs. was the weight that did it but pushed pretty hard. I did not reduce loads to see if the boolit still remained stable at longer ranges.

    My Mihec 434640 casts beautiful boolits and shoots pretty well but so far my H&G #503 outshot it to 50 yards. Not by a lot but better groups. I have not done that comparison to 100 yards yet and I have not down loaded either boolit.
