    I was wondering if anyone out there has ever used Vihtavouri N-140 and Sierra 69 gr Match Kings in either 220 Swift or the 22-250 Ackley Improved? I would appreciate any information, Thank you

    I reload both 220 Swift and 22-250. Tried different powders but not those listed. Best results for the Swift are with IMR 4320. For the 22-250 found H380 to perform best. The Swift has a 1:14 twist and performs best with 50 gr bullets or less. The 22-250 is a 1:12 and likes 55 gr. bullets. Check the twist in your rifles since it may limit bullet weights .
