300 RUM and 8133

Ok so I got a SS Rem 700 long range and got everything assembled last week and loaded up some rounds using 8133. I am shooting the 208 eld-m measurement to the lands was 3.853 so I loaded them to 3.800 ran a ladder from 87 gr up to 92 gr in .5 great increments and loaded 4 rounds at each load weight. Ended up stopping at 91 gr as I was getting really flat primers and sticky bolt lift. Most accurate group was at 88 gr measured .75 inch at 200 yards with 22fps es best es was at 88.5 with 17 fps really started to open up after 85.5 when I hit 90gr es was 78 and just got worse from there. Avg fps at 88 was 2796 and at 90 2959 and 91 3005 but grouping at 91 gr was almost 4 inches at 200 yards. Just figured I would share some information for other folks out there. I really want to try some retumbo but haven't seen it in stock in the past 4 months.

Sorry supposed to say 89.5 not 88.5

I've seen the same large es with 8133 in my 300 Dakota and 270 Sherman. I'm still going to give it a try in a 338 rum soon.

It worked up great in my RUM with 212s averaging 3140 fps. The ES settled in at 9 fps after load tuning. I'm using weight sorted Bertram brass and 92.5 grains of 8133.
