Well, my new chrono is screwed. I managed to clock 1 round, wind took the chrono to the concrete and now it’s toast.

240gr Berry’s Jacketed Target HPs
23.8gr Lil’ Gun
Henry Big Boy 20” Barrel

120315

Unfortunately, those are about 400fps faster than max velocity of these bullets. After I clocked them I went and double checked. Some bullets like 45-70 and 500 mag have a 2000fps max. These only have a 1250fps max. Going to have to do this over again.

The chrono now reads 2444, 2424 and 2442 instead of the 1600 range. I double checked with the 45 Colt loads I just tested. The chrono is screwed.

I will tell you this much, that 44 magnum Henry used to pur like a kitten when firing factory ammo. She kicked like a donkey with those Lil’ Gun loads. I had a heavy leather biker jacket on and the extra zip out coat liner in it and felt it the kick. I’m considering stepping outside my norm and getting some FMJs just for hot 44s. I liked her spunk.

I figured it would have that effect due to the 2gr min to max recipe. Those loads are screaming fast from that Henry. I’ll have to find something else for these bullets. 1600-1750 FPS are just too fast for the bullets.

At least I know that Lil Gun is very case volume sensitive.

With what powders I have on hand, Unique seems the next best. There was no 240gr load data in my book but there was 225gr and 250gr lead cast data. Both say 11gr maximum load.

10gr Unique 1130, 1188
11gr Unique 1383, 1368

I don’t like the 50fps swing in the 10gr, however, it is better than 150 FPS variance we saw with reduced Lil’ Gun loads.

1383 is still 133 FPS faster than bullets are rated for, but better than 400-500 FPS faster. I still need to slow them down a little. 1250 is the max speed.

Ok so now I’m all the more confused. Unfortunately, Berry’s documentation has that effect. It changes on you as I’ve found in the past with 500 mags and 357 mags.

I found a 2019 post where someone contacted Berry’s Manufacturing over a discrepancy on their sight between the 1250 FPS on the box and the 1800 FPS on the site (which is no longer there). The quote from the email stated:

"Sir,
Upon further testing that was done in house on this bullet we did come up with the higher and correct velocities of 1850fps than the 1250fps.
Thank you"

I looked in the barrel for evidence of separation/leading and found only carbon in the barrel, despite the numerous rounds at 1300,1500, 1600 and 1700 FPS velocities.

It’s time to test accuracy and see what the real story is. It’s supposed to rain starting 2:00 and high winds until then.

I’m going to load 10rds at the high velocity with Lil’ Gun and do the same with Unique. There is a 400 FPS difference between those 2 loads. I will sight it with factory jacketed ammo and clock those as well as a baseline. Check the barrel after each set of rounds for indicators or fragmentation/leading and see where we are with each load.

As they say, the proof will be in the pudding.

Lil’ Gun did the best even with the factory rounds. Granted, I was shooting without a rest so some of it was the shooter. These are 8 rounds at 50 yards with the factory buckhorn sights. Shoots about an inch or 2 high at that distance (hard to tell exactly). Probably about a 4” group. Some of it was finding point of impact. There are 5 shots in that bottom group, however, not consecutive.

So this is new. The chamber in the Henry appears to be larger than the 45 Colt. This is the first one I noticed like this. The brass is actually deformed because the expansion was uneven.

The one on the top is the 45 Colt from my Ruger. The one on the bottom is the 44 magnum from the Henry. Notice the 44 appears curved.

120775


Notice the spidering in the brass wall (hope you can see that).

120776


Because of the way it expanded, the mouth is now slanted.

120777


This is the first time I’ve compared the expansion side by side. Had it not been for the deformed case, I may not have realized how much larger the expansion is.

Lil Gun burns really hot. So hot some people have complained about frame cutting in revolvers. Does this look like a combination of large chamber and extreme heat or just over pressure?

Ok, I think I know what happened. Earlier I was testing 230gr 45 ACP bullets in 45 Colt. I loaded 2 then grabbed one from the batch with 250gr bullets to compare. Well... the 44 mags are right next to the 45 Colt box and they are identical. It’s entirely possible I fired a 44 mag from my Ruger Bisley 45 Colt cylinder. I took count of the 45 Colt brass on my table. I only see 2. I know I fired 3. It’s the only explanation I can come up with.

I thought nothing of it when I fired it because I was expecting 1,000 FPS and it clocked at 1,003 FPS.

Edit: that has to be what happened. The brass is too large for the 44 chamber. Ruger has earned a customer for life. I got lucky.

Hodgdon is calling for 27.5 - 29.5gr Lil Gun for JHP 200gr. I haven’t loaded any yet. That’s a lot of Lil Gun. Probably a crushed load. Likely break the 2000 FPS barrier too. Exploring other options I have on hand. Then I’ll make a decision.
