Looking for a good one piece scope base for my rem 700 in 300rum. I have leupold steel rings and vortex viper scope on some cheap 2pc weaver base from cabelas. Now im gunna make you laugh, I put some aluminum foil under the scope in the rear ring to give me some more elevation adjustment. It has actually worked fine for about 250rnds but now zero is off and im ready to buy a 20moa one piece base. They got some inexpensive ones on optics planet, a weaver for like $40, then there's night force for a lot more. Is it worth the price difference? And are steel bases going to be any better than aluminum? I assume that is the main difference between the cheap bases and expensive ones. Thanks for any help.
