cvincent Posted January 2, 2020 Share Posted January 2, 2020 Thanks and one more follow up question if you don’t mind. Crimp or no crimp? If crimp how much? I use a Lee FCD to just remove the flare the the M die produces to seat the bullet. The actual crimping part of the die is just a touch in from doing nothing. So really, no crimp. I haven’t measured it. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

Long story short try this: Load two dummy rounds, one with a crimp and one without. Chamber the rounds 10 times and check the COAL as you go. I no longer crimp.

I inspected the bullet and it was scratched up. I installed the Lee FCD and adjusted until it held consistently after 10x as suggested. Total crimp is less than 0.002” per my measurements so testing starts tomorrow, thanks again. Link to comment Share on other sites More sharing options...

Also as I recollect I had no movement the first few chamberings. How many thousands movement did you get if I may inquire? Link to comment Share on other sites More sharing options...

The highest published load data I know of for 8208 is 23.2 grain on the Hodgdon site for a 77 grain Sierra. I load above that. Link to comment Share on other sites More sharing options...

How many thousands movement did you get if I may inquire? 0.003-0.005” increase in COAL after performing the test in my uncleaned AR with uncrimped rounds. Using a kinetic bullet puller to remove the projectiles took quite a few hard whacks as well so it wasn’t super loose. I’m only using a Lyman M die for prep/bell as the powder charges are added offline for the initial tests. Link to comment Share on other sites More sharing options...
DJRyan13 Posted January 10, 2020 Share Posted January 10, 2020 CFE223 with heavies No reason to use crimp die even when using M die. Just don’t flare. I’ve loaded thousands of 55 SP’s on my MK7 autodrive 1050 without any issue. Never a crimp. All gauge fine. Link to comment Share on other sites More sharing options...
TitoR Posted January 22, 2020 Share Posted January 22, 2020 I use 23.5 g (2,850 FPS)of SW Tactical rifle for 55g and the same loading for 68g (2744 FPS). I am planning to switch from the hornady 68g HPBT to the 77g Nosler CC HPBT w/ cannelure and was in the search for a powder. Since I am new to reloading rifle, I tend to stay away from max charge and look for powders that give me more headroom in the high end to get max velocity with low pressure. From this topic, I reviewed the load information for TAC, CFE223, 8208 XBR, SW Precision Rifle, and varget. I settled on CFE223, because of the above. I’ll report back when I get a chance to load and test some.Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
K-Texas Posted February 22, 2020 Share Posted February 22, 2020 TAC with the Hornady 75 gr. BTHP Match with cannelure. Western provides true 5.56mm NATO data. Others stick a heavier bullet into a .223 REM case and call it 5.56mm NATO. Testing the Hornady against the Sierra 77 gr. HPBT w/cannelure, both open-tip match, reproducing the Mk 262 load, the Sierra doesn't hold up well in water jug tests at 50 yards. That's at 2700 FPS. The Hornady 75 gr. at 2750 FPS, both velocities from 16" barrels, is better constructed. Sub MOA for 5 rounds at 100 yards and the load is not a Max Charge. AA 2520 is also good, but SDs are better with TAC. AA 2460 will also get 2750 FPS with the 75 gr. Hornady, but closer to a Max Charge. This load is essentially a replication of the Hornady Tap 2 factory load as well as their 75 gr. 5.56mm NATO Match load, Link to comment Share on other sites More sharing options...

99mpower Posted May 21, 2020 Share Posted May 21, 2020 TAC and 8208 for 77 and 80 and 80.5 gn stuff. I load 80/80.5 for single loading at 600yd line for NRA/CMP stuff. 77gn with 8208 all day Link to comment Share on other sites More sharing options...
ARBilly Posted May 30, 2020 Share Posted May 30, 2020 I get great velocity and accuracy using CFE223 behind 55-60gr bullets. With 77gr SMK CFE223 gave good velocity but couldn't find the accuracy that Varget gave. I single load 77 SMKs with Varget using the Charge master lite.
