New here looking for 350 Legend bore/groove bullet input

[Hazcat]

The new 350 legend is what I'm looking at. The off the shelf bullets loaded for this are .355 and from what I understand the gun mfgs are using 9mm barrels which as I am sure you know are .347 bore / .355 groove. I am looking at building a .350 upper and McGowen barrels chambers the 350 legend in a barrel that is .350 bore / .357 groove. I do want to hand load for this but I want to be able to shoot 'off the shelf' ammo as well. Would the McGowen barrel work for that or is it too large to shoot off the shelf ammo with any reasonable accuracy? Here is a link to the barrel sizes http://mcgowenbarrel.com/4933-2/#crownjump

Curious. Why 350 legend? If not hunting in a state that requires straight walled cartridges, I don't see the appeal. Comparable decent energy at the muzzle, but then it quickly drops off. 6.8 and 6.5g are nearly identical at the muzzle, then start to kick 350 at 100 yards and it is a rapid decline for the 350 from there. By 200 yards, 300 blackout is already the better choice for a hunting round. The BC on the 350 sucks as well. I just don't see the craze unless one is hunting in a place that requires a straight walled cartridge.

I have always liked the 30-30 and the 350 is basically a semi-auto 30-30. Hits hard and shoots soft. 200-250 yards is enough for me.

I don’t have any numbers, but I believe a 6.8spc is gonna get you closest to the energy of the 30-30 in an ar-15 semi auto. A lot closer than the 350 at least. I’m with ReservoirDawg10 I don’t get the fascination with 350, but variety is the spice of life, if you want it go for it.

Spice of life is fun and all, wholly agree there. I just see see the need. You are actually handicapping yourself with 350 legend. 6.8 spc is withing 20 ftlbs at the muzzle, some better than 350 some just under, depending on common ammo selections.

I never worry with muzzle energy too much on hunting round. Only occasionally do I shoot a deer that is inside 15 yards. The and 100 and 200 yard energy are the measurements that matter in the field.

Agreed. But that's really the only distance the the 350 competes. It drops like a rock. My point was that 350 at the muzzle isn't event great. Get to 100+ and the 6.8 and 6.5g are clear winners
