What is the difference in price? I lean towards the Greener crossbolt, think of it as your catistrofic damage insurance policy. The hidden third bite is better than not having a third bite, but not as good as the Greener crossbolt. Do you need it for a 45/70? No, but it is comforting to know it is there, especially when there is so much spread in the loading intensity of the 45/70 cartridge. You never know what somebody down the line will put in your gun.
