My hornet with any load is louder than a 22 RF, much louder usually. Don't expect a miracle in the sound output dept and still get a good hunter that exceeds the 22 LR performance. Although delivered energy will be much higher at any velocity with a 55gr.
Granted, a CB (cast bullet) load thats moving 1600 fps with 55 gr has longer legs than the 22LR and is “almost” equal in quiet, it's a heck of a lot more expensive than a 22 LR even in PRE-Obamarama pricing days and just as rainbow in trajectory. I bought my k-hornet with quiet and subtle in mind. HAH!! OOPS!! Relatively quiet compared to a 223 and just as much muzzle rise unless underloaded to the point of economic waste. Relatively MAGNUM compared to a 22 LR in both rise and report. I don't know if one can get a hornet to subsonic....safely. .5gr bulleye????????? Well theres someone who has and done it well, they will reply and fill the gap for you. I would like to know your progress personally for my pistol. Keep me informed if you would.
Lyman 45th shows:
45gr GC, 225438,
Unique 3.5-5 gr
2400 6-8 gr
IMR4227 7-9gr
50gr GC, 225415,
Unique 3.5-5gr
2400 6-8gr
IMR4227 7-9gr
Each load has a minimum 600 fps spread from start to max. 50 grain CB data spread reduced to about 400 fps.
None exceed 2260
Yes, I did NOT type incorrect. Both 45 and 50 gr data is same load charge, for variable velocity.
All data using Lyman #2 alloy and .224 bullets, not .223/
Above should lead you in a good direction for a 55 gr workup and cast. For reference to 55 gr actual data....
55 gr jacketed
2400 8-9gr
IMR4227 8.5-10gr
IMR4198 9.5-11gr
same data book.
Interpolate as required to generate start loads.
