Had my 357 zero’d for deer hunting this year. I wouldn’t mind getting an 18” 223 Wylde or 6ARC barrel as a “truck gun”.

Thanks for sharing the MV data for your 18" "general purpose rifle!" That's the sort of data that I'm searching for! The MV data that your shared for your 103-grain handloads with the LVR powder is very close to the same MVs that I've seen on-line so far for 20" barreled rifles shooting that same bullet and powder. The MV data that I've seen on-line for 18" barreled rifles shooting 103-grain bullets with LVR averaged around 2,635 fps. However, unlike your data, no ambient air temperature information was provided for those MVs of around 2,635 fps and 2,685 fps from 18" and 20" barreled rifles, respectively. I now suspect that those MVs were shot with cooler air temperatures than the 85-degree conditions under which you shot your MV average of 2,685.4 fps with an 18" barreled rifle. Do you have any other MV data that you could share for your 18" barreled rifle while shooting 103-grain ELD-X bullets with LVR powder, under cooler weather conditions?The information you're looking for and more has been discussed in this thread, worth doing some reading there.
New 6mm Advanced Rifle Cartridge
I hadn't seen this posted here yet, but SAAMI added a 6mm Grendel derivative called the 6mm Advanced Rifle Cartridge or 6mm ARC to their newly accepted cartridges list. 6mm ARC introduction pdf The case looks like the shoulder has been moved back, and the neck is a little shorter as compared...www.snipershide.com
I have a 21", an 18", had a 12.5", and have a 13" on order. My 18" is my general purpose rifle, light enough for hunting and accurate/fast enough for non-match range use. Outside of a more specialized range only gun, I don't have any interest in going longer again, and sometimes think the 18" would be better as a 16", but it shoots too good to chop or replace. The 13" should scratch that itch and be another good hunting rifle though.
Here's one of my go to loads for the 18":

It's accurate and I wound up using it in a 12.5" upper to take two deer this year, worked well, although was starting out closer to 2,400 fps in that barrel length. LVR gives top velocity and good accuracy in the ARC, but the price you pay is temp sensitivity and it's fairly dirty.
I did play with AR-Comp some and it shows promise at lower velocities, but I suspect is probably still over gas-gun pressures.

Most folks using a gas gun seem to be using factory ammo, or loads with LVR, AA2520 or CFE223. It also seems like a lot of the bolt breakage stories seem to come from people trying to run Varget and the like at decent velocities.
