I'd like to see if my fast twist barrel will shoot 40grn bullets so only need about 10 heads to reload and see.
Willing to buy or swap 10 heads 40grns preferably VMax or Nosler BT. I have 150grn .308 sierras or 55grn .223 Nosler BTs that I can swap. Somewhere close to Staffs/Cannock would be great. Face to face as these are expanding heads so usual rules apply.
