Just finished some really interesting tests with the .444P Outfitter.
I have my pet loads that I hunt with, and decided to do some serious load development using the .432"-280g WFNGC bullet. All loads with bullet seated to a C.O.L. of 2.51"
Starting with H335, results were less than impressive:
.432"-280g WFNGC/59.0g H335/WLRP/Rem Brass/2167 fps.
Then switched to RL-7 and really got an eye full! Here are some results... kept going up in charges, and pressure signs just weren't there. Checked primers, extraction and case head expansion, using all new brass. These tests conducted at 22 degrees f.
<span style='color:blue'>Please note! These loads were worked up at 22 degrees f! Pressures could and probably will be significantly higher at higher ambient temperatures! Use caution, if working up loads, and remember that the results here that were safe at the 22 degrees will likely be excessive at higher temperatures!</span>
All loads using .432"-280g WFNGC/WLRP/Rem Brass/C.O.L. 2.51"
48.0g RL-7/2207 fps
50.0g RL-7/2300 fps
52.0g RL-7/2375 fps
53.0g RL-7/2400 fps
54.0g RL-7/2434 fps
55.0g RL-7/2478 fps
56.0g RL-7/2510 fps
And these loads were from the ported barrel of a .444P Outfitter!
Now, I tried the 56.0g RL-7 in my old 444SS Micro-Groove barrel gun and got 2594 fps!
Move over .375 H&H! These loads are really a powerhouse combination for the .444!
The Outfitter was very pleasant to shoot, and the top load generated MOA performance and an Extreme Spread of 9 fps!
This was a surprise to me, as previously about 2350 was my top load with IMR 4895.
Thought you .444 shooters might appreciate this!
God Bless,
