Thread: Where to from here with my 7WSM?

Get a chronny and take note of the most efficient powder charge. I.e the point where extra powder charge doesn't equate to extra velocity as previously noted. Back off from there and you will find the efficient charge where you are getting good extreme spreed/deviation.
They are a fricken science to get them to shoot so make sure you have a good stock.
168s have been my favorite pills of all the 7mms

Yeah, that was my approach with W760 until I ran out and couldn’t get more… best results used 59 grains and 35 thou jump (I tested in 30 thou steps out to 120 thou). It was getting .75 - 1.0” groups but trundling along at 2880 fps. I wanted to push them a bit faster than that (the Federal factory ammo was doing 3130).

I’m hoping it’s just a case of my rifle not liking them - otherwise I’m just a crap shot! I wouldn’t rule that out, but I have had a mate shoot it and he didn’t do much better.

I was tempted to try the 168 ABLRs but after my experience with the 150s I don’t really want to go down that rabbit-hole with such a spendy projectile.
