[QUOTE="Trickymissfit, post: 457926, member: 25383"] Kieth: I'd be carefull about that extra two or three grains of powder. Not saying it won't work for you, but move up slowly as that's a big jump and the pressure spike nearly squares itself. I think the issue here is a compound thing that is rather common with Remington rifles. First thing I'd check is the actual chamber deminsions (not the throat!). I have seen many Remingtons that had the necks chambered almost .100" longer that the case spec. That can be a good thing as well as a bad thing. Of course you will almost never have to trim cases! (I like that part!) So brass flow is not a major issue with the exception of the "dreaded doughnut" in the neck. The next issue is that it appears that Remington is adding some freebore to the throat to further reduce recoil. My next step would be a chamber & throat cast just to see what is actually there. My guess is that you have a chamber with plenty of free bore cut in it. If the rifle shoots good for you, I'd just live with it! Seat the bullets out to to what you consider to be safe in the neck, and have fun. The otherway (if you don't like the long throat) is to do a three thread setback on the barrel, and then rechamber to what you are after. This will take about .180" out of the throat (you could go .240" and take it all out). Myself, I'd live with it for awhile gary [/QUOTE]
