Picked up 1 K of the 62 grain 5.56 tracers bullets from Wideners also 1 k of their non burn 308 bullets tracer bullets.
Anyone got any experence with these bullets from Wideners?
Got the 308 to run thru my FAL's, ordered the 5.56 because they were cheap and had to pay the haz mat fee anyway for the 308's.
thanks in advance.
