22 Grendel 40? IMP

[Es 350]

From what I could find on the web last night. The 22 grendel out runs 224V with same length barrels and same weight bullets.

So I think your 22 grendel/40 deg/alk should be a lil bit faster then all three of the other chambers.

The AR bolt will be the limiting factor in that platform and is one ithe reasons i am thinking of chambering a barrel for bolt gun.

During my initial load ladder in the 22.5" 14 twist barrel i hit 3840 fps with a 53 gr bullet with no excess pressure indicators. Im sure this was a high pressure load and do not plan to shoot loads this hot.
Part of going this high was CFE , with its high temp stability factor, i was shooting ladder loads that had been in 31deg. For quite some time. I then loaded 3 more at 2 tenths progressively , the first .2 higher than previous was 100 fps faster!
The 3 hottest loads showed no signs of pressure on primer and primer pockets measured same as new brass.

So in a bolt gun should work great with not having to worry about bolt strength.

Have asked on other 224 Grendel sites about case capacity,
with no reply..... necked down Hornady brass before fireform
Vs my fireformed brass = 1.7 gr more H2O. Have several 224V range pick ups , have not measured volume but is easily seen the normal Grendel has more capacity.

Also have .4 gr (53gr) and 1.5-1.7 gr (75 &88gr) more H2O capacity than 22 Nosler according to Nosler data.
