Ive got the Rock Chucker supreme kit on the way from Midway right now along with the latest nosler reloading book. So far from the research Ive done RL-17, RL-19 and IMR 4350 seem to be pretty good powders for this load and either Winchester or CCI large rifle magnum primers. Anyone out there loading for this round that can share some ideas and starting points Recommendations on a decent caliper and chrony would also be appreciated. They like a fair amount of jump into the riflings to get the tight groups youll be looking for and has a very low ES and SD with what we run. Good luck. With the 180 AB, Im shooting 64.0 grains of H414. The 180 AB load I listed is on the upper end of the pressure spectrum so start a couple grains below for safety. Im going to try the 190 ABLR through mine this summer after it gets rebuilt. Also, there isnt much data around for RE-17 yet, so you might have to dig around for some safe charge range data, or find someone with Quick Load to get you started if thats the powder you choose to go with. Been using H4350 with CCI magnum primers behind 165 grain accubonds. Sub MOA. I also worked up a load with Hogden superformance and CCI large rifle primers pushing 150 grain sierra game kings that groups MOA or better. I will go look up the exact charge weights and get back to you. One thing you might want to consider is the 200 grain bullet since the ballistic coefficient jumps from 0.507 at 180 grains to 0.588 at 200 grains. That is a 15 jump, pretty significant. I am trying to extend the range of my 300 WSM and my next load will likely be a 210 grain Nosler Accubond Long Range (if I can find some) or a 210 grain Berger VLD Hunting bullet. Wind drift is about 15 less with the 200 grain (vs 180 grain) bullet at 400 yards. I am holding off to develop a new load until I can get my hands on the 210 grain Accubond Long Range. Ballistic Coefficient (Nosler specs): 180 grain Accubond: 0.507 200 grain Accubond: 0.588 190 grain Accubond Long Range: 0.640 210 grain Accubond Long Range: 0.730. Those might be worth a look if they live up to the reputation of the standard accubonds. Any advantages or disadvantages to using this over regular brass.
