        I’ll have to try that one. I somehow ended up with 3 lbs of IMR-4166 at a cheap price and have been wondering what to try it in first. I’ve got a 20″ x 1:8″ twist RRA upper that ought to do well with that load.

            28.2/2922
            28.4/2923

            Looks like the velocity flattened out 28.0-28.4. No swipes. Primers all looked fine. Case head measurements were consistant with pre-fired.

            Will post some accuracy info after I shoot for groups.

              I see lots of recipes for different barrels, but none for the I’m loading for.

              Anyone have a fav recipe they like for a 16″ 5.56 1:7 twist, chrome lined barrel, with the RMR .224 69gr BTHP?

                      I have a nice load with RMR 69’s using 25gr Shooters World match @ 25 gr’s
                      OAL 2.250, cci 450 srp. Even my 1in 9 twist likes em. My 1 in 8 twists will shoot this load in an inch@ 100yds.

                        I shoot the RMR 69 bthp mostly out of 18″ 1:8 upper, 24.24 grains imr 4046 at col of 2.255.
                        I also have a heavy barrel bolt gun I use with a couple higher priced bullets . I decided to load up some rmr 69s, 23.5 grains imr 4064 with a little longer col of 2.315 to use as fowlers and they shot amazingly well, my 1st 3 shots had a spread of .292″, the 4th was off so stretched that group to .568…thats pretty decent for a bullet which cost 15 cents

                          Today I am trying a load of 25,5 gn of TAC Mil Brass, Fed primers, in 2 rifles a 5.56 1:7.5 Wylde Chamber and a Contender Carbine that I built several years ago with a Green Mountain Barrel that is pretty stiff and 20″ long. The 5.56 AR also has a 20″ barrel. I was just wondering if anybody else was using TAC powder? Has anyone shot coyotes with these bullets, if so, what was the hide damage? TIA

                            The 69 3GH bullets are good for the price point, but don’t expect them to be a Sierra Matchking.

                            TAC is a great powder for these.

                            I have not done any hunting with them.
