Re: Anyone try Reloader 17 yet?
I have an older prochrony that's about 15 years old. The sensors are only 1' apart. I do think it's *fairly* accurate because other loads seem to match fairly close to published data in velocity and factory loads also matcth fairly close. The first 3 shots had an ES of 19 and the fourth made it 46. I have been fairly careful with my reloading practices but haven't culled much brass except by case legnth. I've been using a Redding neck die and competition seater, but will be switching to the Type "S" competiton bushing dies in the 300 RUM, complete with turned necks. The brass in the WSM have been fired anywhere from once to four times, so there may be a little difference in case stretch/capacity and neck hardness/tension. This was just for initial load development. Tha accuracy in this rifle is not good with any factory ammo or handload, so I cant comement on the powders accuracy for this gun and load other than it's consistant with other loads.
Yeah, it's quite close to RUM performance, 200 fps more than what I was getting with H4350. I would really like to see someone try it in a 7mm or 300 Dakota which has about the same diameter case as the WSM (and RUM). I think the Dakota could possibly give the RUM a real run for it's money.
It will be very interesting to see the "slow burning counter part" to RL17. Hopefully these powders are temp stable. Last year hunting temps ranged from 75 in Oct, hunting antelope to -10 in Dec hunting late season elk. Temp stable powder is crititcal here for LRH. RL22 wont cut it for me although it's a good velocity performer.
