    Haha, the “friend” category losing bullets does include me, too. We’ve collectively lost several flavors of 7mm’s. Not a 195 though, that friend nice enough to run the traps with the 195’s was Joe Regina. I it was at Berger too lol.

    Just waiting on a new reamer to build the new rifle. Everything else, including 1,000 184s is ready and waiting.

    Hi Montana, no mate, we're just about screwed over here as far as Berger bullets go. There are still a few .30cal bullet options available, but as far as 6mm, 6.5mm and 7mm Berger bullets go, both local suppliers are pretty much out of stock. The Berger factory relocation really played havoc over here with both suppliers having multiple orders placed, but no incoming shipments coming for some time still. I've got enough 180gr VLDs to see me through the next 12 months, but I have gone over to 105gr 6mm Lapua Scenar L bullets for my 6BRA and plan to test those this weekend as my Berger 108gr BTs are almost gone - got about 200 left.

    No idea when we will see the 184s, they have been ordered but I reckon the second half of 2019 is the probably the earliest we'll see them.

    7mm RSAUM WENT BACK OUT Today. Slowed them down to 2950fps. Much better results.
    Here is 3 shots at 1000 yards today. This will be my final load for up.coming nationals at Raton New Mexico

    Nice group! What is that maybe about 3” ( Can’t tell without a reference )... but very nice group. It looks like those 184’s like your 2,950 FPS.

    Are you in the lands? Or jumping?

    If you were planning a reamer for the 184’s, how much if any would you push out the freebore? Currently running .235 for the 180’s.

    I run a 0.235 Freebore on my 180 Hybrid’s ...and also on my 184’s. The 184’s seem to like it....
    3.87” group at 1,000 yards.

    This was measured in a new unfired Bartlein .284 cut with .295 FB.
    The brass is also unfired.

    It works fine right there but I have considered sending it back to JGS and have the FB moved back to about .275

    Barry: awesome!
    What freebore did you run with on the 180 Hybrids?
    Have you shot the 184’s in your 0.295 Freebore yet? Any results?

    For what its worth I have shot a little over 500 of the 184's thru a new barrel and my reamer with a .220 freebore. I am not into the donut and I am no closer to the donut than with the 180 hybrids. I think this works because the ogive is different and has a longer taper on the 184.

    My 184's mic a little smaller in dia. than the 180's also. .2839 in the middle of the bearing surface and .284 at the pressure ring on the 184 VS .2841 in the middle of the bearing surface and .2842 at the pressure ring on the 180. My load and chrono data has been very close to one another with both bullets. YMMV
