Mmmm, speaking from personal experiance, having had to use leadfree due to this being specified by landowners, i find that the lead free rounds i have used are in no way inferior and in fact in 22wmr they have performed better in terms of trajectory with terminal results for both the calibres i have tried being very impressive added to this the 22wmr rounds are £9.25 a box instead of £14, whats not to like?
