I find 4227 leaves a lot of powder in my Bulldog's 2.5 inch barrel, and cylinder. Accuracy only adequate. I put it back on the shelf since I found some 2400.

I guess I'm different from the rest. I want a light load.
I just got a United Sporting Arms Abilene 44 mag 7.5" made in Tucson by Sig Himmellman back in '79 or '80. I spent 4 days testing my new reloads and that hogleg. Also a TC Contender with a 14" barrel.
I am senior who is looking for a light load to shoot 100 yard plus gongs. I love the heavy bullets that make that gong sing.
Grouping Target was at 25 yards with chrono at 4 yards. 95 degrees with little wind. loads were kept in the shade.
Tried IMR 4227 in 44 mag case with a cast 300g FT GC over
16.5g 946 - 1150fps 2" group Abilene 7.5"
16.5g 1065 - 1085 1.5 group TC 14"
17.0g 990 - 1013 1.0 group Abilene 7.5" Accuracy excellent for me
17.0g 1094 - 1095 1.5 group TC 14"
17.5g 990 - 1050 1.5 group Abilene
18.0g 1010 - 1050 2.0 group Abilene
18.6g 1052 Abilene
These were all mild, low recoil. The 4227 with a LP magnum primer produced medium dirty guns. The accuracy was good. The brass looked dirty, and primers looked normal.
and now 4227 in 44 Special cases with a cast 300g FT GC over
9.75g 645 Abilene mouse fart
10.5g 590 - 635 2" Abilene
10.5g 683 TC
11.0g 630 - 660 1.25" Abilene
11.0g 690 TC
11.5g 754 TC mild and pleasant, could use more grains
Note the 30-50fps boost from the 7.5" to 14" barrel with no B/C gap. I expected a bigger difference. Unburnt powder granules were seen in the cylinder. TC shooting 700fps seems the spot were unburnt powder seems to be less.
Two rounds were loaded with bullet sticking out to magnum length. They shot normal and accurate.
I also made up some of the same testing rounds using Titegroup, but I'll save those results for another thread besides the 4227. I have many other columns in my spreadsheet - date, lot no, variance, POI, ...
4227 has been my goto powder for shooting 357 maximum. This was my first foray into 44mag and 44spl. I also did the same testing techniques with 357 mag Trail Boss and 2400 shooting a cast 180g FT GC in a light load.

So I'm guessing I should quit buying H-110? I have a hundred rounds of reloads for my Maximum I'm scared to shoot. I see my top strap starting to erode. I wonder if I could buy the insert that came on my Smith M&P snubby and put one on my Maximum so I can shoot those rounds instead of pull those rounds.

Those .357 Maximums bad with eroding?

Yes I hear they are with h-110. But I heard there is another powder that's not to harsh on them.

4227 is a great powder for the 45-70 as well. I shoot a 300gr hard cast, and a stiff load of 4227 will push that sucker to 2215fps out of my 18.5" barrel.

. You could take a buffalo with that load. Like a small freight train!txpitdog said:
