I have two Remingtons that I use T7 in. I have used the #11mag caps in the past and the only time I everhad any trouble with ignition was in the coldest temps (below zero).

You do not say whether you are new to the gun or not, but be aware the bolt must be dis-assembled and cleaned on a regular basis or it will hang up and will not set off the cap. A lot of blow back goes back up into the bolt assembly. Remington also used a very minimal firing pin spring - I think they were 24lb - I have changed both of mine to 26 lb and have a 28lb available - never have needed it since changing to the 26.

Good luck enjoy your Remington 700 it is a good accurate gun.
