Henry Big Boy 41 Mag: review and test

Blued Steel Frame and 20" (Rifle) Barrel (1:18.75 twist).

Like and dislikes:
I like the stock fit and "cut" checkering.
I'm not crazy about the bead blasted finish of the receiver and I'm not crazy about the unpolished barrel with machining lines and matching mag tube.
I do like the mag tube loading, as opposed to marlin's feed gate in receiver.

Last night, I attempted to cycle some ammo I had previously loaded for the Marlin and my pistols. The Ammo loaded for the marlin had a OAL a bit too long for the Henry, The Henry appears to have a tighter chamber or a shorter chamber (that appears to be almost 0.100" shorter?), but that longer ammo would cycle, but it took more force than I like, to close the bolt. None of my pistol ammo would successfully cycle 100% of the time...about 25% or so would jam (FTF)...(three different cast bullet ammo and 3 different jacketed bullet ammo).

So, today, I set out to load some ammo to test it, I hope to go to the range tomorrow (it's suppose to be a beautiful sunny day, should be 46º and little or no breeze). I had some Saeco 411 SWC 232gr. that were cast/sized/lubed from 2013 (sized .411 -Tamarack lube). They were cast from an Alloy I guessed to be COWW from a couple homemade boat anchors that I melted. The BHN measured 11 in 2013, but today I it measured at 16.6, I did several samples, to be sure. My notes from 2013 indicated that I added one ingot of a zinc contaminated alloy to the 3/4 full Lee pot, a common practice of mine, to use up the contaminated alloy. My best guess is that Zinc content couldn't be more than 2%. The bullets do have a bit of a galvanized finish, LOL.

Anyway, I set out to make some dummy rounds to find a OAL that'd work, I made 4 of each.
what I found:
1.715 was too long, and would jam on the way up from the Mag tube. I started here because this was a good length to be seated to allow crimping into crimp groove.
1.700 worked
1.680 worked (almost 100% of the time)
1.665 failed part of the time
1.630 failed much of the time (this OAL had the case mouth about lined up with the front of the driving band)

First, I should add that initially I had problems cycling all of the SWC dummy rounds, til I cycled the action a few hundred times. I'm not sure if the action just needed to be broke-in, or I needed to develop a nice smooth movement to open and close the action...because that seemed to help...Obviously I was always holding the gun, in shooting position, sites up.

I was cycling these dummy rounds for hours...The conclusion: the cartridges with a shorter OAL seemed to "flop around" in the receiver, causing more chances for misalignment. Usually what would happen, is the ejection pin would push the rear of the cartridge sideways (outward of the ejection port), which would move the cartridge so the position of the primer are centered on the extractor, which then would push the nose of the bullet the opposite way, into the side of the chamber entry. JAM !

I hope this gun doesn't end up as finicky as it seems right now.

So, Once I seemingly figured out the OAL (1.695), I loaded up a box of 50 with standard Win primers and 11.7gr of vintage (Hercules) Blue Dot. Lyman says it should be moving about 1025 fps and around 20Kcup.

I'll take some photos when I get out to the range, tomorrow is the plan.
:cool:

The rim should be guided by the lifter up between the ejector and extractor, not be pushed over in front of the extractor. Something is up with the ejector, like it's bent outward too far at the tip. The tip of my .45 Colt ejector is parallel to the bore line when the bolt is all the way back, and the bottom side of the tip is beveled so the case rim can push up beside it with just a little tension and be captured between the ejector and extractor until the bolt is moved forward enough to push the extractor back out of the way.

Looking at that closer, The ejector looks as you discribe. But...I see that the bolt face (when all the way back), is about 1/4" farther back, than the back "ledge" (stop) of the lifter. So when the cartridge is lifted, it is well in front of the extractor (I was using one of my shorter OAL dummy cartridges), as the bolt comes forward, if I move the lever slowly and smooth and steady, the cartridge snaps into the extractor and against the bolt face. But when I cycle the action faster (especially if I do so in a herky jerky fashion), that short OAL cartridge flops and hops and does as I mention in the OP...NOT everytime, about 1 in 4.

I didn't double check the longer OAL, that was working earlier today as I mention in the OP...But the gun will get a workout tomorrow.

also, I didn't specify in the OP, but the Ranch Dog 255gr RF boolit cycled flawlessly, but the only rounds I had, were too long of a OAL. I would have loaded some of those, but don't have any laying around...and I wanted to use this SWC, my Marlin doesn't cycle a SWC very well and someone on the other forum said his Henry cycled SWC real well...which makes me want to try a SWC in the Henry.

Greetings
Our Marlin CCL is very picky about which cast loads it will cycle. Round nose is OK . Truncated generally OK. But SWC is a big issue. LBT flats are impossible.
Our Henry did real well with all but the LBT Wide FN.

I didn't mention this earlier, but while I thought the Ranchdog ammo (I assembled a while back for my Marlin) had a long OAL for the Henry, I also suspected the nose/driving band of the Ranchdog bullet was unsized and larger that .411 (those were sized in a Lyman 45).

The boolits I cast on Monday, and sized last night, before I sized them, the base measured .411 and the nose or driving band in front of the TL area measures .413 I was kind of surprised.
But I set up the Star, and applied GC's and sized them...so these will be .411 all the way.

Sidenote:
I had to "double pump" the Star to completely fill in The TL area. I've never had to do that before? ...I don't think it's a larger amount of lube, but the more resistance the TL area creates. Anyone else ever run into that?

I'm not overly familiar with the boolit.
but the bands might be right against the holes or covering half a hole or have a band on each side of the hole.
your adjustment could be like 1/8th turn on the punch.

If my thinker is remembering right that RD bullet was designed with a fat nose to better fill the fat throat Marlin was reaming the 41 mags to. That bullet has no issues in our 41 CCL but needs nose sized for our Contender barrels, the DW revolver and the JES Rebore we have in 414 Supermag.

Lamar,
I did try changing the depth, a few times. My Star die has 4 rows of staggered holes (3 on each depth). The top row is plugged, and the bottom row is plugged.
The TL grooves of the Ranch Dog, do touch the die, just barely, I guess that is probably why the resistance...I do hear a squeak/squirt type of noise during the second pump, LOL :rolleyes:

I could open up all the holes, but then I'd just have to plug them for single groove SWC bullets :confused:

OK, good to know. I was worried the measurements indicated a goofed up mold.

the second pump is breaking the lube around the bands it sounds like.
I'd probably just go with 2 grooves filled anyway.
 

JonB

Halcyon member
the first pump gets the middle 3 TL grooves of the 6 or 7 bands.
a few years ago, when I sized/lubed this bullet for the Marlin, in a Lyman sizer, I lubed the bottom three only(but it was a different lube, my homemade modified version of speed green), and from tes shooting some, it seemingly didn't have enough lube, so then rolled those remaining ones in BLL...problem solved.
Anyway, I felt compelled to fill these up with SL68B.

I thought I'd wake up this thread.

I've had this Henry to the range several times since March. I'm still having some issues. I believe I finally found a Bullet that solved some of the feeding issues (NOE 412-238 WFN), but I still have the occasional FTF/FTE jam. I sent Henry the email shown below, last Saturday and heard back from them, they said, "Send it in". They are mailing me a prepaid UPS label.

Hi,
I bought my first Henry, a Big Boy H012M41 (41 Mag) in Feb 2017. I love the rifle and it's accurate.

BUT, it has had FTF (fail to feed) and FTE (fail to eject) issues since I bought it. I didn't contact Henry right away, because I wanted to give the rifle a good workout and try different ammo. I have shot about 500 rounds through it so far...and still does the same thing.

The problem I am about to describe only happens about 10% of the time, the other 90% of the time, the rifle functions as it should. Also, when I get a FTF or FTE, it doesn't matter how full or empty the magazine tube is, the issue seems random.

About one round in every magazine full will not feed into the chamber, The jam seems to be NOT be happening with the round that is suppose to go into the chamber, but the next round (from the mag tube) is either pushed back into the tube, or it gets pushed to far backward in the rear of the lower receiver area.

I believe the issue is with something in the action that is suppose to hold the next round (from the mag tube) in place during firing, I am assuming it's suppose to be halfway out of the mag tube, but I guess I'm not 100% sure of that, as this is the only Henry I've ever owned, but when the rifle is in that condition when I cycle the action to chamber a round, then it functions as it should. I'm thinking the recoil moves that next round, because when I cycle dummy rounds, I can't recreate the problem.

Also, I own a Marlin 1894 (also 41 Mag), The action parts, specifically the carrier (or lifter?) does NOT have any 'play'. The Henry action parts, specifically the carrier (or lifter?) does have 'play' and seems loose for my tastes. Is the Henry design suppose to be loose and have some play?

Lastly, I did buy this Rifle New, from a Henry Gold Dealer.

Thanks in advance
Jon

Nice to know they didn't quibble and just said send it to us. Would be nice if they also let you know what the issue may be so that the rest of could know. I was eye balling Henry's in the store yesterday but I got lucky, no 41, 44 or 45 Colt or my wallet would no doubt be lighter & slimmer, they sure is pretty. They had 22's. a 357 and a 30-30 & that's it.

Don’t have a Henry, but my Marlin likes Lyman 41028, which is a semi -flat round nose (not a scientific term). I did finally get it to feed some SWC boolits after I radiused the mouth of the chamber ever so slightly.

I do like your continuation of this thread and am anxious to know how Henry addresses your issue.

Jon, that cartridge popping halfway under the lifter sounds a lot like the dreaded "Marlin jam".
