Yesterday I promised to post what loads shot well using Rem 7 1/2 Primers. I couldn't find the thread where I made the promise, so I'll just list them on a new thread.
These loads were shot in a 222 magnum, which is very close to the 223. I interchange loads between the two chamberings as there's only one grain of water difference between the two in case capacity.
The first load that shot well was 27.5 grains of TAC with Sierra's 40 grain Blitz bullet and the 7 1/2 primers. Three shots into a 7/16" group at 100 yards.
The other was with Berger's 50 and 52 Varmint bullets, same powder and charge as above, that shot 3/8" groups at 100 yards.
TAC has been a very good powder for both the 223 and the 222 Rem Mag.
19.5 grains of IMR-4198 with Berger bullets again and Rem 7 1/2's shot around 1/2" for 3 shots at 100 yards.
So, I found a good use for the Rem 7 1/2 primers I have.
