I just got the news I drew a tag for deer this fall in Montana and want to take my new toy my 257 mag. I want to try a few loads using 110 acc bonds and hornady 110 interbonds. I'd like to try Retumbo, but don't have data for 110 just 100 and 115 and 120 gr. I know i should just stat low an work up but would like to hear if anyone has had good luck with this load. I also have 100 gr partioners and different powders. I have IMR4350, H1000,RL19 RL22 and H 4831SC. Any info will help.

i shoot 72 grns IMR 7828. i use weatherby brass also. work up to this it is over book max.3.250 coal
