20" Craddock RTR 1:7"
29.5gr CFE223 75 ELDM @ 2.240 = 2950fps
.6" for 5rds, .6" for 5rds, .74" for 5rds, .63" for 5rds, and .76" for 5rds. Two groups would've been .42" and .34" except for first and last round fliers. This load shot 3030 ft per second at about 1.5" in a 22" Baldwin gun works 22 Grendel barrel.
26gr 8208, 75 ELDM @ 2.280 = 2899fps
most accurate at .37" for 5rds
26.5gr 8208, 75 ELDM @ 2.280 = 2950fps
.46" for 5rds
27gr 8208, 75 ELDM @ 2.280 = 2999fps
least accurate at .74" for 5rds and showing pressure
Used my old 22 Grendel brass and just ran it through the new Lee 22 ARC dies. I still had 60 rounds of 22 Grendel(CFE load) loaded up. I shot 30rds of it to help get zeroed, set the gas block, and run some rounds through thru the barrel before testing the 8208 loads. Everything functions fine but headspace on the 22G brass and ammo was 1.174 and fired brass from the Craddock 22ARC is 1.181. Same BCG and rifle parts; just pulled the 22G barrel and replaced with the 22A barrel. Used the Hornady headspace comparator and .400" insert to measure the shoulders. I'm looking forward to trying some TAC and maybe even some StaBall 6.5.
Hoping I can get sub .5" consistently at 3000fps plus once the barrel speeds up and brass is sized correctly. Hopefully TAC can get me there. If it doesn't work out, I at least have 8208 at mid 2900s was excellent accuracy.

I'm going to reshoot it tomorrow. I put some side weights on the foreend and the mlok screws caused some fliers. Had to file them down. Definitely showed some promise
No luck today. I loaded the 75's at 2.250" and shot some 1 - 1.8" groups. Definitely got the velocity I wanted but accuracy lacked. I will try some more seating depths but as of now TAC doesn't look promising. Which is a shame bc I like that powder and have a lot of it. I might try Varget, 6.5 StaBall, or N150 next.
Try the 75 eldm @ 2.30 OAL. Mine didn't tighten up until I got down to 556 velocities.
TAC still isn't doing great for me. 2.230" definitely opens up. 2.240" seems to be the sweet spot. I shot the last 10rds of 22 Grendel ammo I had loaded up. 29.5gr CFE223, 75ELDM at 2.240. Still shoots good with that load. Think I'm done with TAC.
I cut little boxes out of the paper bc I ran out of pasters. There's two rounds inside the little cutout in group #2.

How many gr of CFE to get the 80 to 3100? What about the 53?
I'm testing the 62gr ELD-VT. Factory ammo is running 3200 from my 20" .
Curious to see your results on how yhe factory ammo groups. I used to have a 22 grendel and sold it out of necessity at the time. Thinking it might be time to get back into one. It would be great to not have to do all the brass prep and handload again.
I have the 75 eldm and 88eldm factory ammo. I can test it sometime soon.
