That's what she said :XD: should be plenty, I haven't measured the jump or anything.

I chronod some Norma and hornady 143 out of my new 22 inch suppressed custom today. The Norma were doing 2700 on the button. Shot well enough printing between 3/4 of an inch and an inch. Very consistent though ex over 5 rounds was 7fps. Pretty impressive.
The hornady chronod much faster at around 2830. Tighter groups in my gun printing 1/2 to 3/4 moa but a larger es of around 30.
If it prints close enough to either berger 140 vld hunters or hornady 147 eld m in hand load development ill probably use it for an up close load.
I see the 143 Norma projectiles are available but at a very stonch price, heard good terminal reviews on them @2950
Its weird that the Norma ammo is so pedestrian - Ive been shooting Norma 130 gn 6.5x284 target ammo and it honks, over 3100fps from a 24". You'd think that they'd be similar given they are ballistically ide tical . . .
Quite a big difference between the two bullet weights there @Tentman even in published load data.
Nosler list their 130 weight bullets doing 3200 fps out of the PRC with H1000 (2217) and down at 3030fps with a 140 weight bullet. That's from a 26 inch barrel mind you.
With my first lot of reloads I'm back up to 2770fps with the 147 ELD-M, plenty of bang flop out a long way. I think there is also an advantage of running a custom barrel in your case, excited to see what you end up running in yours.
