Re: DANGEROUS LOADING PRACTICES
Posted: Tue Apr 30, 2019 6:08 pmYeah. Definitely taper crimp to about .475-.474. And 37.0-38.0 grains of Lilgun is probably the best starting load for the 450 Bushmaster 250 gr FTX bullets. You want a good crimp to help the powder achieve complete ignition and burn. CCI 450 are pretty close to the 41s. It’s just that the 41s have a harder metal cap so as to reduce dinged primers in the military M16 autos plus it’s a hot primer to assure ignition in various temps. At least that’s what I was told.
