I reckon you'll find your chrony is slow. Gunwerks have a good free ballistics solver/truer on their website that you can use to true velocity

Yeah the 150's over rl17 will get things humming. Fella on the other forum getting 2900ish with the same load

Adi lists max load for 2209 and a 140 as 57 gr. They have it as a compresed load. Maybe try 2208 or go to a heavier projectile get that pressure up a bit. Will be shooting alot of unburnt powder out...

Yeah that seems super slow. I'm at 2750 in a 19 inch Barrel with the 162's and 52.7 414. 55gr 2209 sounds light behind a 140. Maybe stoke her up a bit.

That does seem a little slow. That said, it is only a 17 inch Barrel and 2650 with the eld m is still plenty to reach out to 500.

Norma brass is softish and I notice does tend to stamp a little...
