New 8mm ammo from Marushin

Hi folks,
I have just received a batch of the New .40 gr bb`s from Marushin. These should be perfect in your M2 carbines etc.. I always found the .34`s too light and the .45`s too heavy.
I cannot test them yet though as I have my carbine stripped down to fit a new tightbore barrel that I am trying out. It is an inexpensive length of seamless alloy tube that I have to machine to accept the hop rubber and the two locating circlips. I cannot finish it for a couple of weeks as we are on holliday tomorrow.
I will report back when I have the job done and tried the new ammo.

chin,chin.
