The 150 gr 350 legend win xp list it at over 2300fps. The 170gr barbs at over 2200fps
The 1900 fps is about what I get out of a 357 mag withb16 gr of 296 in a rifle.
Yes it's slower than a 308 but much better than you are saying. Why 350 low recoil, low noise, ammo on the shelf when nothing else was, puts deer down fast within its intended range (limited experience of 2 shot during youth season but im very satisfied so far). Few deer are shot over 100 yards around here. Furthest I have shot one was 302 with muzzle loader. But that was because i had a good back stop and was on a walker and limited mobility at the time. Watched that doe go down in the scope. Personally I like a 7mm-08 better than a 308 for deer and would not pick a 350 if not for our limited public cal restrictions but I sure don't feel the kids are under guned and will be just as happy with them hunting with the 350 if they want as the 243 or7/08 when not hunting in a restricted location. Just my personal experience this far
that is why I asked Why? if you have a reason then it makes sense. if you're just being marketed at that 350 is bigger and newer than 308 and your being sold on marketing hype of the new thing, then step back and think about your why more.
like with the kids and public land you have a good reason
just like I own the 300blackout because of a very specific township we hunt.
I went back to check the velocities I used Winchester power points 180gr for both ammo
the 2620 is muzzle on the 308 and I did make the mistake of 1926 being the 50 yard velocity for the 180 gr 350 legend
I like 180gr 308 loads for hunting that is why I used it for comparison, I got tired of not getting a hole out the other side with some rounds I run a muzzle brake and can watch rounds impact in the scope.
that 2620fps 308win falls down to the 50 yard legend velocity at 300 yards the ballistic coefficient is a lot better on the 308
just past 300 yards 350 legend falls sub sonic
the 350L is not a long range gun so if your saying , I had rotator cuff surgery Doc said go real easy on recoil and you want a sub 150 yard gun and never plan to need further than go 350
I like the 308 because with a 200 yard zero it is very forgiving if you were off on your range a little
just know the why , is what I was saying.
