Has anyone seen any non lead bullet options for the 348 Winchester. Someone shared that Barnes made them for a couple of years but stopped due to low demand.

Barnes did make them.
They occasionally come available from shooters who no longer need them. An old box of 50 Barnes-X bullets will probably sell for around $75 plus shipping.
I think North Fork will also make mono bullets for your 348.

I would give Barnes and North Fork and Cutting Edge bullets a call. One or more of them might make a custom run for you.

CEB makes one called lever raptor

Should be able to get it moving comfortably around 2700-2800fps

Search on .348.

I have had great success with the Hawk Bullets

I shoot the Barnes Originals, mostly the 220 gr. but they do make a 200 gr. and they are available in several places..I also like the 250 gr. Woodleighs, they are awesome on big bull elk from any angle..Old gun, old bullets suit me...using light bullets in the .348 seem to be akin to trying to make a silk purse from a sows ear! just a curmudgeon, traditional old timers point of view!
