It usually is a mistake to pass on a "good deal"! If you can't really use it ,you can get more back in a trade.I know!! I've made a few of these mistakes myself! I have the 358318 and 358315 along with acouple others. The 200 grain bullets are mean coming out of the 358 jdj,haven't got to try them at 100 yds yet(weather&range repairs). Have not tried to chrono them yet either.they make great light plinking loads for the Whelen
and I do not worry about velocity for plinking loads. If I can hit a cola bottle at 50 yds ,it's a good load.
