This has been a very exciting week indeed! Variation has returned giving permission for .375 and .458, a 2021 trip abroad has been approved by SWMBO and booked, and a 375 H&H is inbound (although slowly) to Ronin for borescope and function assessment prior to final purchase. I sourced cases, cheapish bullets for practice and dies so have been playing around getting some preliminary loads sorted. Now I haven’t ever used crimps for any of my rifle reloads, only revolvers in the past so am unsure about how much crimp is enough and how much is too much? Close observation shows there is a slight bulge just below the crimp that measures 0.403 whilst mid neck measures 0.398. Providing the neck section of the chamber exceeds the diameter of the bulge then they should chamber OK. What do you guys think about the amount of roll crimp in the photo?
I will probably get round to getting a Lee Factory Crimp die but don’t have one yet, so this was crimped using the RCBS seater die with the seater stem backed out, so that the bullet was not seated deeper during crimping.
