    310 grs. in .44Magnum

    I just brewed, lubed & gas-checked my first batch of Lee 310 grs._ they are cast for a .444 Marlin, but I would be interested trying them in .44 magnum sixgun_
    in .44 magnum they will be tested on a 9.5" Ruger SRH, and my intention is to work with the powders that I have at hand: Vihtavuori N 120, N110, N320_ also N 310 available_ I'm considering starting from levels of heavy .44spl upwards, since the fun here will be purely against the paper_
    If anyone has direct experience with this, I will be very interested_
    thanks to all

    This is a Lee 310 over 15 grs of 2400, I shot this just a few weeks ago out of the Henry.

    ...Do you feel it particularly stout/punishing in your rifle?

    Lyman Cast Handbook 50th edition has some data for this 310 LEE bullet in 44 magnum.

    In my Ruger SBH 7.5" (Loaded to the REAR crimp groove -- i.e. LONGEST assembled length) I find it gives ~ 1200-1300 fps with WC820, W296, Alliant 2400 & Power Pro 300 MP with good accuracy.
    My velocities exceeded those printed in the Lyman manual.
    WC820 at 21 gr for 1300 fps was tested in a friends pressure rig -- 31,800 psi -- I MUST stress: Loaded to the REAR crimp groove -- i.e. LONGEST assembled length.


    Didn't work well on deer for me, and I found it did not give that good of cavitation cavity in wet newsprint either, compared to some other bullet designs (Lee seems to round the nose slightly for release purposes). It did however seem to give better newsprint cavitation (and penetration) than 30-06 165 gr Hornady SST at 15 yards (of course, this distance could have greatly disadvantaged the 30 cal jacketed).

    Accuracy of the bullet in my gun was good, but not best of the varieties I have tried.

    Overall, I would say good bullet in 44, but I have found better.

    Not at all, but the Henry with the octagon barrel is a little heavier than a Marlin or Rossi.
    It sure smacks the big gong in the backyard, it's 50 yds from the porch.

    My 9.5" SRH loves this boolit (310 Lee) but heck, it shoots everything I've fed it great. My 4" S&W 629 shoots this big boolit better than any other, using H110 but the recoil in that gun HURTS. Sorry, but I don't have the powders you mentioned. I have used the rear crimp groove and the 1 thing I have against this mold is the shallow crimp groove. If I was a dedicated 300gr+ shooter, I would order a custom mold with a deeper crimp groove but I am a 255 gr guy. That long barrel on your gun will get you some good velocity out of lower loads. For instance- my 4" 629 gets about 1050fps from 16.6gr of Alliant 2400 and my Ruger SRH 9.5" gets 1225fps out of the same load. You will hear a lot of people stating that the SRH us an ugly duckling but IMHO it is the most accurate revolver made.

    I have that 310 mold and removed the gas check by drilling to the lube groove with a .436 =7/16 bit and resizing to .432. My mold dropped at .429 and too small for my cylinder and does fine without the gas check and saves .08 cents a pop. It shoots good but a lot higher using 2400 powder. I have a SRH that likes it but haven't shot through my Marlin yet. I plan to shortly at 100 yards. The bullet has plenty of kick. I have a 788 Remington 44 mag also but never shot lead through it. My shooting buddy has a Freedom Arms that shoots them very accurate. So for I am testing with starting loads. The LEE book has lots of info for this boolit. <For the Freedom Arms I have to size .430>

    Thanks for the many inputs.
    somehow I can carefully extrapolate and convert the data with the VV N110_.
    for me it is important to get something that is reasonably manageable without hunting needs.
    btw I got my best satisfaction on the 29s with gas checked Lee 240 grs HP, but I think that was mainly due to the fact that they came from a single-cavity mold_

    thank you, sir: I will search on both my Lee manuals, if that's what you mean by Lee book, with more attention_

    Caution about downloading slow burning magnum powders, some you can to a certain extent, others like W296/H110 don't go below published starting weight for the load you are building.

    With heavy for caliber boolits like the Lee C430-310-RF I have good luck with 2400 and LilGun in a 7 1/2" SBH right at 1180-1200fps. I wouldn't try for the fastest powder, you generally can't make magnum power before you run out of pressure headroom with heavy boolit and faster powders.

    The other thing about the 310 is that it REQUIRES SPIN to stabilize! You HAVE to drive it. It's not a target boolit by any means. The slower twist in the barrel, the faster you have to push it if you hope to build an accurate load. By the way, the hunting load will likely be the most accurate.

    N110, H110 and LilGun are real close in burn rate according to Hodgdon, they are grouped together on the burn rate chart, with N110 being the faster one of the three, but I don't think you can interchange charge weights with N110 and H110, they are different powders.
    Got a .22 .30 .32 .357 .38 .40 .41 .44 .45 .480 or .500 S&W cylinder that needs throats honed? 9mm, 10mm/40S&W, 45 ACP pistol barrel that won't "plunk" your handloads? 480 Ruger or 475 Linebaugh cylinder that needs the "step" reamed to 6 30min chamfer?

    ...thanks about all above.
    personally I have always perceived the N110 to be faster than stated, but maybe it's me, and it's a purely empirical perception.
    I'm still curious about the possible use of N120, but it's really entering some no man's land, in this case_

    wilecoyote, I have a 310 Lee that drops at .431 but like 45Dude said, they are famous for dropping skinny boolits. I don't know whether you can get molds from the US but Accurate has a 43-310G mold that has a double crimp groove. My Lee has a seriously shallow crimp groove and with a boolit that heavy, you need some really good crimp.

    45 Dude, you should give the Lyman 429421 a ride in that 788. I had one that shot that boolit into less than an inch at 100yds with 2400. Of course ,like the gun swapping fool that I am, I traded it off.

    murf205--I have that mold also. I used it in my 29-2 on the low side. I have the gas check version also. I like 2400--What powder were you using with the 1'' group?

    2400. It has always been a good performer for me. I believe it was 21 grs with that boolit.

    murf205 and 45DUDE, if apparently I don't interfere in the discussion it's because I'm hidden here, absorbing what comes out of it: btw I bought a 429421 a few months ago and I have yet to try it, and from what I see it would seem that the N110 powder I have in hand is just a little slower than the Alliant 2400, but on the safe side, on my book .
    now I have the 310s on the bench hand which I can't wait to test in SRH without fear of stressing the 29s_
    about some serious crimping, DougGuy posted something that I have yet to try but it seems of extreme interest to me:
    https://castboolits.gunloads.com/sho...=1#post2239315 _
    now more than a tread it seems like brainstorming to me , but I am very pleased that the stars are aligning, even in unexpected ways, with the contribution of all of you.

    I never shot the 310 out of my S&W and sold it for a good price 3 years ago. I had it since 1982 and didn't wont to stress it out with heavy loads. My shooting buddy has a Freedom Arms 44 mag with a 1 in 20 twist and a waste of time shooting against him with my SRH. I shoot his gun very well. He uses H110 and W296 but my boolits group in his gun wit 2400. The range is under a remodel for another week. Maybe I can post a 100 yard target with the 429241 mold in the next couple of weeks from his gun on the bench and the 310s also. I do all the boolit casting and prefer a hard boolit. DoughGuy and Larry Gibson seem to have the better answers with testing.

    just to make you understand the diversity of our market/availability conditions, I don't know that an FA in .44magnum has ever been imported here. _
    from here on, including molds and powders, you can have an idea, even though I am among the lucky ones around here, with about twenty years collecting reloading equipment, manuals, molds, etc. inherent to the few calibers with which I have fun.
    you can therefore imagine how much interest I can read and hopefully learn from your various answers...
