Finally, today, one of my local ranges opened for shooting, after several weeks of Covid- lockdown. I have a new .35 Whelen barrel for my Rem 700 custom switch- barrel, that I never have tried. New barrel, new cartridge- my first 35- cal. Re-formed Rem 30-06 cases. Win LR primers. Only powder coated bullets today.
My ambitions for this range trip, was to fire-form some brass, and get some basic data- points.
I loaded some cartridges with the Lee 358-158- RF, sized .358/.359. N110 20- 21grs. This load was to timid, soot on the necks and unimpressive accuracy (3-6 MOA...). I think I`ll revisit this bullet with some faster powder, it is intended as a «component saver».
I had some MP 360-200, loaded with N140. 48 grs (2150 fps) and 50 (2230 fps). These groups were more promising. 50 grs N140, and size .358 gave a group at roughly 1 MOA. Probably a fluke, we`ll see. I`ll hang around this level a bit, to experiment with various sizes, cartridge lengths and so on.
I shot one group with the MP 360-220 HP- bullet, and 48grs N140 (2140 fps). With the flier, 2 MOA. I was fighting mirage from the suppressor at this point (the range was closing, had to hurry!).
Still early days. But I think this will be a shooter, after I have figured it out
