Help with 41gnr, 41 gnr.

[needsmostuff]

Looking for any help I can get on loads for the elusive 41 gnr. Mucho internet searching has only got me the 25-29 gr 296 with 170gr bullets option. There must be more testing being done out there.
As my launcher is a redhawk snubby my needs are a little different. I think I'm looking for a heavyier slug at medium speed that will not set my hair on fire when I pull the trigger.
Would ya'll feel safe starting with any mild to mid 44 mag loads and a like weight bullet as a starting spot?
Help me keep my fingers.

for 10 dollars Gary Reeder will send you his reloading manual with the reloading info for all the GNR's.

I'd bet that if you contact Gary he will send you the short list he provides with the conversion..

I have not seen the Reeder list of loads but was told it was kind of short concerning the 41 gnr and leaned toward the longer barrel hunting loads. If that is all there is available I guess I will contact him but I was kinda hoping some one had stirred the pot a little and tried some home brews.

I have tried Lil Gun, 2400, 4227, H110/W296. The load I settled on was 29grs of W296 behind the 170JHC (This is also the Load Gary swears by also). BTW This is on the revolver platform, For Deer sized game (and at least 1 250lb porker) that bullets is a great killer. I have also used the 210gr XTP but I found the 170 was just more accurate. I also used the 250gr thru 265gr LBT style bullets but I am more inclined to use the lighter weight HP for the type of hunting I do.

For Velocity you will not beat the H110/W296. Lil Gun came close but still was 100fps lacking. They were all accurate but I like W296 and I stuck with it.

You could start at 23 grs of w296 with a CP 250gr WFNGC. With the different styles that will put the bullet further out in the case I am hesitant to recommend a starting load without seeing the projectile first. Just rememebr not to download W296/H110. 2400 is a bit more forgiving but didn't seem to do as well with the 220gr+ bullets as it did with the HP's.

For projectiles I seem to have 170 and 210 sierra JHP and some CP cast 250 gas checked. I was leaning toward trying some 4227 as it would fill the case nicely. I need a starting place for that. What would constitute dangerous downloading of 296. I cranked out a couple of 25 gr /296 with 170/ 210 gr sierra last night but haven't shot yet.
As this is a snubby gun I thought the 250 cast gaschecks would make a wicked defence round but did not know where to start there other than some cast bullet 44mag loads?

I've pretty much come back to Gary's suggested 170 & 210 loads, having tried Cast Performance 255's and 265's several years ago.

I'll look in my load data tonite, but I recall, of the two, the 255's shot better than the 265's in my gun, but still not as good as with 210's.

One of these days I'm going to try the Barnes 180 XPB's.

H110 / W296 should not be reduced more than 10% from maximum. My practice here is to either follow the load data specifically - even bullet - or run the load density calculation myself since bullet designs (even of the same weight) often vary enough to change the load density.

Personally, I'm in the heavy and "slow" camp. My .41 GNR being the one exception.

I started with 27.5grs of W296 under the 170. That 25gr/170 load should be fine but I like a nice full case with that powder.

The load for the 210gr is just about right. You can watch for pressure signs the whole way up to 27grs but I never went past that. It was accurate with 26.5 (W296) and the 210 XTP.

The 250 is not a great defense choice for 2 legged varmints but it will do just fine. I just mean it will penetrate forever but that isn't always good. I'd go with the 210 if that was me (just my 2 cents worth)I can't remember what my load was for 4227 and the CP bullet. I'll check at home but if you use the other loads as a "guide" you will see that some 44 loads will get you in the ballpark with the powder. These "wildcat" cartridges are just that and should be approached with some know how and common sense.

Don't trust what you read when it's your fingers that could be lost, I am not saying this info is bad info... I would just verify it before proceeding....I'd still get with Gary on what loads he has experimented with.

BTW as of that last post I want to mention that the 255CP and the 250CP are a little bit different design. I actually had the best luck with the 250 but the 255 was a close second for accuracy.

Groo here
If you want an easy load ,fill to the bottom of a cast bullet with Trailbos powder.
I would expect 800+

[needsmostuff]

Well, It does seem like most experiments work thier way back to the 170/220 grain 26/27 gr 296 load (sounds alot like a rifle recipe), I would still like to try some 4227 but it sounds like no real improvment to be had. And maybe another can of h110 needs to find it's way here.
Now I gota wait for the weekend.
Thanks ALL.

Starline 44 mag. case, CCI LPMAG primer, 27gr. H-110, Swift 210 HP hollow point A-frame Bullets. Clocked 1780fps from 6" revolver.

Also remember that H110 & Winchester 296 are the exact same powder now, although the price can be different.

I have a 5.5" 5-shot Super Blackhawk with both .41 Magnum and .41 GNR cylinders...

170 Sierra:
.41 Magnum: 26.0 H110/1530
.41 GNR: 29.5 H110/1580

This round really needs a long barrel or Contender take full advantage of the extra powder.

I had a 5.5" Redhawk-- this is not a recommendation this is just the info you asked for--start lower
170 with 28.5 es was 5-6 fed 155-- 1665 bef0re conversation 1580 // 29.5 of 296 = 1728
210 gold not deep curl-- 23 gr AA#9= 1458 with 26 grain of 296 =1501 before conversation 1390
240 gr LBT Gc 21.5 AA#9 1502 before mid 1300s
Remington 200 gr HP 26/296=1524 es 30 fps
220 gr K. (lyman 410459) 22gr AA#9= 1572
230 gr Saeco .411 K 22 gr AA#9=1483fps
255 LWN GC Mountain Mold//20.5 =1340 shot through a European boar 270# several times
255LWngc 24 gr of h110 = 1360FPS
305 GR PLAYED WITH NEVER really tired as it way too long for the .41 GNR //19gr AA#8= 1202/1218/1215
loads from a normal .41 Redhawk 5.5"
230 gr K=1360
225 K 1375
my 9" TC .41 gnr give about 250-300 more fps so add 270 fps per second to the 6 gun loads
212 gr cast Hp in the TC =1850 fps
hope this helps it was fun to learn --START LOW --not recommending these
