284 load speeds

hi anybody using a 284 with 162amax 18" barrel what speed are you getting from it?thanks

20 in bbl 2850 fps with Superformance powder

2820 in 24" bbl with 2209, but thats the sweet spot. can get 3000 with no signs of pressure

I'm getting 2740 with 162g Amax in 17" barrel.

Thanks for input

22 inch barrel, 53.5 of 2209, 2750 ft/Sec, however I've got two bottles of R17...

Bring on the longer days!
