Well, I bought it almost 2 weeks ago and finally got to take it out today. It doesnt recoil too bad at all. It ended up being fairly accurate. About 1 MOA with factory ammo. The federal 150 grain loads chrono'd at 3100 on the money. The package said 3200, but I am not upset with that. It will probably only digest my reloads from now on. Two thumbs up from me! EJ
I have a Super Shadow as well and love the gun/caliber. Dropped a muley at about 50/60 yards. He took 10-15 steps and was done. May try it on speed goats next year.
For reloads, I got good results with 140gr Accubonds and Reloder 19. Avg 3038 fps at .8" with a 5 shot group at 100yds. I still want to fire at least 20 more rounds to see if this is indeed the load or if more tweaking is needed.
I am gonna try to get a 140 grain load that will do 3200. I want it flat! Those speed goats were real far off this year, I want as little drop as possible. Mind sharing your grain weight of powder? EJ
How fast have you pushed it? One of the few advantages to a 7mm WSM over a rem mag is the sammi rating is 65000 on a WSM and 61000 on a rem. I plan to get 3200 out of a 140 grain, if I can safely. EJ
Sorry I don't know because I didn't have my chrony with me on the day i was shooting work ups. I started at 65.5 and went up to 67.5 66.5 gave me the best accuracy. The next trip I had my chrony and averaged 3038. At 67.5 I didn't notice any pressure signs, but was happy with the accuracy of the 66.5 so that is where I stopped.
Well, a pal O mine got me a pound of magpro and I guess I am gonna try to load some hornady 139 grain BTSP's and aim for 3200. They say with 75 grains you can get like 3270 out of it. I aint interested in anything over 3200 fps but I'd like to get right at it. They say that Magpro is specifically designed for short magnums. We'll see. EJ
Let me know how your workup goes. I would suspect at 75grs you may be filling the case to full capacity. I guess it will depend on the consistancy of the Magpro compared to RL19. I'm workinga load for my .300wsmusing 70.5of RL19 with a 168 Barnes TSX andits definitely a compressed load. According to the Barnes manual 71grs is max. Of course the Barnes are on the long side some what too.
