Re: Rutumbo in a 300 Ultra
Thanks for all the info. I tried Retumbo yesterday using 200 Accubonds and 90 grains of powder. I was beginning to get extractor marks so it looked as though that was as high as I could go. I was only getting a little over 3100 in speed. I was not able to tell if I still got a fireball but I am thinking for my rifle Retumbo is still too slow. At least I am not able to obtain the speed others are getting. Maybe Ill try H1000 or R 25 next.
I did switch to R22 and at 91.5 grains I was getting over 3650 average and und .5 groups. I appreciate everyone input and advice.
