If you open a "hammerless" ejector rifle enough to load it and close it enough to fire it you have cocked it for sure. The extra stiffness of a hammerless ejector is absolutely unnoticed on reload, in the feild. And it is faster than an extractor gun, period. I don't think its any big issue though for the fellow who becomes adept at reloading an extractor gun. And an automatic safety can be disconnected to make it work the way it should.

I don't own a hammer gun, but use on occasion a freinds hammer gun. It is slower for me by alot, and for him too. This might be a factor but not a huge one imo. The biggest problem my feind has encountered in the feild is a hammer slipping while he is mounting. In some guns this can lead to firing, some just the need to recock, but its an issue. Also, a toplever or underlever, but not a Jones under lever are fast. Even a snap Jones underlever takes too much manipulation imo. You can reload an ejector or extractor, top lever, self cocking rifle on the run, probably not a Jones hammer rifle.

Add up all the slowdowns and issues and I thinks its pretty obvious you're working with a considerable handicap.

But a slow opening, slow reloading, slow closing and slow cocking DR will still give you two rounds. If the charge comes out of the blue, thats all you'll likely get anyway. If it comes on follow up you will have reloaded already. If it comes after the shot you better hope your PH can shoot!
