Hi I have not reloaded 7mm rem mag before .the question I have do u full size down to belt in cartridge or all the way down to shell holder thanks
 
I set my magnums to headspace on the shoulder and not the belt. I smoke the cases and resize till the die just touches the shoulder then try it in the gun to see if it chambers easy, if not I turn the die down a tiny bit till it does. Some people like to feel a slight resistance when chambering a round but in my hunting rifles I like a slick chambering with no discernible resistance.
 
Like most belted cases they respond best when you size to just barely bump the shoulder like beltless cases but you gen into trouble when the base of the case has expanded to where chambering becomes difficult, what to do !?
Normal reloading practise dictates that you should lower you sizing die to reduce the case dimensions further thus allowing easier chambering of coarse this also creates more headspace so your methods will be a compromise in order to achieve some harmony.
The ideal method would be a die that only sizes the base and one for the rest of the case of coarse this combination does not exist,.....kinda! There is a company that makes a resizing die for the base (whose name escapes me) of belted cartridges and this with a combination of either a neck, body die, collet die or full length die would make a great combo for precise reloading of belted cases. Unless you are full length resizing these difficulties will always be present in belted cases, depends on the chamber dimensions, location of belt to shoulder and diameter of fired case at base with those of the reloading dies.
Hope this helps.

Thanks .I use to reload 22 250 and 30 06 20 years ago .this belted case is new to me .thanks for all the replays great site .
 
I have cases fired 5 times. Resized with normal dies. Lee full sizing die and Lee collet neck sizing die. Never had a problem with the cartridge case expanding near the head. I don’t shoot extra hot loads,though.

X2 works great ! Imho
 
Full-length resizing may shorten brass life, limit the number of reloadings, but should still get 5 or 6 loads so for worry free loading and shooting, FL is the way to go.
