Have question about cutting a barrel. Can someone explain the difference in ballistic performance between a factory made say 12"(or what ever length) 1:7 twist barrel compared to a 12" that was cut from a 20" barrel with a 1:7 twist? Looking a doing another SBR, and finding the proper barrel has been difficult.
What difference in MOA would i see from a factory made short barrel vs a cut barrel of the same length?
