Hornady has the 129gr Interbond, 129gr SST, 129gr SP, and 130gr ELD-M bundled together.
The 129gr SP is shorter and has a flat base, so you can generally get a little more powder under it for a bit faster mv, though it doesnt retain momentum as well as the others with their higher BCs.
Doesnt really matter much for typical hunting distances because it still has a decent mid- .4s BC.
From an 18, you should have no problem reaching over 2400fps with CFE223 or Leverevolution.
If you have MLGS gas port location, you will want to know your port diameter and might need to choke it to get the maximum velocities.
At 2410fps mv, you have:
350yds 1805fps 933ft-lbs
At 2350fps mv:
325yds 1802fps 930ft-lbs
Due to the SP design, these bullets impact with a pretty loud wallop. Its a great basic soft point hunting bullet that isnt pushed too fast, and has plenty of tail-end to plow through for deep penetration. Depending on impact speed/distance, you may or may not see an exit with broadside shots, but internal damage will be significant.
You might be surprised with its accuracy due to the flat base design.
Start at 29.0gr of CFE223 and work up to 30.7gr.
Dont go above 31.0gr of Leverevolution.
Find your COL that will reliably mag-feed and not jam the lands. If you find yourself able to load longer than 2.260, you can get a little more powder in, but Im not sure it will do much for you. You can see how it performs already even at 2360fps.
