A .41 Magnum kinda thing

I know that I'm talking about the loadings.
Defend your post, but don't miss that people compromise to lose a round to a smaller gun and also typically don't care to carry an N-frame or one of similar size in order to maintain a six round capacity. Six 41 Specials fit in a GP100, a medium size, .357 Mag platform. It appears that 41 Magnum potential pressure levels are judged to safely require a heavier cylinder and frame without reducing round count.
 
I just took these pics in response to a PM. I have almost finished the sight painting (I need to trim the excess and sand it to a matte finish). But I thought I'd share these with you guys.

There is quite a bit of load data available online, I have someone's compiled spreadsheet on it, I can scan it and send it to you, just PM me. I downloaded it mostly for the cast bullet data, but it has a lot of everything. Even Hodgdon's online data has data for bullet weights up to 265grn... so it's out there.

Another good powder for the .41 is Unique... but you probably already knew that.

I appreciate that Charlie! I think I'm going to stick to 210-220gr bullets, at least for now, so I can set and forget the sights. But I'll try to remember that you have that heavy bullet data, just in case. Though honestly, the .44 mags might see that as their territory. ;)

Ok. I like th .41 mag. The n frame is not that big compared to an L frame or GP size platform so the loadings to me were what really killed it.
 
Don’t overlook IMR4227 with the Hornady 210gr XTP.

That was the Golden Nugget I discovered about 2 years ago... IMR4227 in the .41! Even under a commercial cast 215grn SWC, it shot extremely well... with a little more reach than my normal Unique load (9.0grn) and a lot less blast than a charge of H110/W296. I was shooting the IMR4227/215grn combo out of my 4" Smith and hitting steel at 500yds easy-peasy.

I to have found IMR a real pleasure to shoot. I’ve never shot at 500 yards with my pistol. Are you shooting at large steel silhouette targets?

We were shooting at hanging steel pipe. The target at 500yds was probably 3'x3' squareish. With the Smith, I started close and worked my way out, adjusting my holdover. After about 2 cylinders I was getting 6 of 6 on the 500yd pretty easily.

Wow, that’s impressive. My club doesn’t have a 500 yard range, but I do have a 200 yard facility. I think I’ll start there and see what happens. Thanks for your input.
 
My notes tell me it was 19.5grn IMR4227 under a 215grn commercial cast SWC.

1060 out of my 4" Smith, 1210fps out of my 6" Dan Wesson, 1475fps out of my 20" 1894

A lot of similarity in our 4227 loads. I’m loading 19gr IMR4227 with a 210gr Hornady XTP. For my plinking rounds I’m loading 8 gr of Unique with a plated FPRN. Accuracy out of my Ruger Super Blackhawk Hunter / 7-1/2” barrel is excellent with both. There is a pretty big gap in point of impact. I don’t have a chrony so I can say what my speed is.
 
RANGE REPORT:

Today I loaded up 50 new Starline cartridges with 210gr XTPs over 15.0grs of 2400 and CCI 300 Large Pistol primers. 16.0gr is the suggested starting load, but I know 2400 has a wide safe range of use as far as pressure goes, and I assumed I needed to zero the sights. I also loaded 50 rounds of Acme coated 215gr LSWC with the same brass, primers and powder, also at 15.0grs.

I shot the XTPs first so I could check for leading with the Acme bullets. I had a minor issue with the coating when seating the bullets. But I will address that in the ."41 Magnum Association" thread.

I set the target out at 10yds and fired a few XTPs, then did some sight adjustments. Lather, rinse, repeat. Then out a little further to 15yds and did the same a little more.

Side Note: I was sitting, benched, with a rubber rest. But was still not feeling confident in my abilities to rest any part of the gun on the rest directly, which has not worked out well in the past. So instead I lay my dominant forearm on the rest, and use a two handed grip. This is not entirely stable, but usually yields more consistent results than anything else I've tried so far.

Then, with 20 rounds left, I shot 4 groups on 4 targets at 25yds, whilst adjusting the sights between each group. The groups were all 5 shots. Although the other 3 weren't too much worse, this is the best one of the session. At 2-1/8" including the one at bottom left:

I know. Just dancing around that bullseye!

I then tried the same shooting with the lead. I may have been tired by that point, but the groups were not nearly as good. So I used most of that batch for off-hand and "rapid" fire, which was much more fun anyway! :D

I had a great time! Everything fired first time, despite my concerns about the reduced power 18# main spring. The gun ran smoothly except for the ejector, which seems to be a rough edge on the housing, that never the less did not create a function issue. And the SBH hammer felt good, cocking either strong hand or support hand. Overall a very pleasing range trip with this gun.
 
I just picked up some .41 cal 180 gr zinc cast bullets for 6.99 per hundred.

I’m a Unique fan with all of my revolver cartridges (.38,.357,.41,.44 Spl,.44 Mag,.45 Colt) because it just seems to work. It’s not always the best for velocity, but I’m not much of a hot rodder with my reloads so it works for me.

Glad to see another person got hit by the .41 bug :thumbup:.

Stay safe!

Check out Penn Bullets. They make some fine dedicated .41 mag cast bullets intended to be run full-house. They will also cast in a softer "cowboy" alloy for no upcharge if you want some soft shooting ".41 specials" over Trail boss, unique, or red dot etc. They do limited runs of .41, so order well ahead of the time you will need them. I find myself shooting mine much more with soft loads than heavies these days.

BTW, I've had zero luck with coated bullets and my Lee dies. With the Missouri Hi-tek, the seating die takes the coating off the front driving band, resulting in leading even at modest velocities. I need to give them a swipe of sizing lube after loading just to use them up. Have gone back to conventional cast/lubed in this caliber.

I checked my lead SWCs against the flat-head seating plug and found that, if the bullet tip is not fully supported, the knife edge around the flat plug will cut the leading band of the lead, shaving off the coating. In that case, I expect the concave seating plug for round nose might actually work better. The issue is that the SWC nose is too short. It is also possible that if the current seating plug is shaped for round nose, a switch to the flat nose optional plug would fix the issue.
