1 piece scope base or 2 piece?

I was shopping for a new base and I see there's 1 piece bases and 2 piece bases. Is one better than the other or is it really just personal preference?GL

    I prefer 2-piece bases, mostly because of the reduction (slight, I admit) in weight. I can't imagine a 1-piece adding anything towards stiffness in today's typical actions. With bolt actions a 2-piece can make cartridge ejection & (if you shoot single-round on a sled) insertion more convenient.I'd welcome the opinions of others' as well; I have a nice M70 Classic Stainless 300 WinMag that I bought used with a one-piece Leupold mount & was wondering if it be worth the cost to replace it with a 2-piece of the same brand.

    i cant prove it but logically a one-piece base is more apt to stay in line when tapping than two-piece bases which in turn could bend a scope slightly if rigid and misaligned.i agree on the weight thing.also two piece bases are much cheaper. barto

    One peice bases were designed and intended to lend structural rigidity to the actions of the rifles they were mounted on. Indeed they do tend to stay in alignment better than two peice bases, provided the tapped holes in the action are perfectly aligned. They also often tend to make access to the cartridges and magazine a little tighter and more awkward. I have two piece bases on almost all of my rifles, but I do tend to use high end rings and bases like Talley and Conotrol.

    With todays magnum calibers, a single piece base would add rigidity to a flatbottom receiver like that of the Winchesters, but with the bar stock Remington's I see no benefit, since they are a true cylindrical receiver. I prefer 2 piece bases on my hunting rifles, but I use single piece bases on my varmint and tactical "style" rifles because they provide a offset cant for the scope and make them easier to zero at extended ranges

    Orphanedcowboy - not sure on what you mean by "they provide a offset cant for the scope and make them easier to zero at extended ranges". Can you elaborate?

    contrary to popular belief a 2 piece base will do a better job simply because they mount with all four of the provided mounting screws. the one piece bases use only 3. also the 2 piece bases are able to be aligned better. i put a thin coat of brownells glass bed under my bases to make sure they perfectly conform to every inch of mounting surface on the top of the action. that way there is no room for any kind of movement. i also prefer dual dovetail mounts with burris signature rings. and the mounts in no way provide any more rigidity or strength as far as trying to stiffen up the action

    bullhauler - does the glass bed mess up the finish on the top of the receiver/action, when or if you take the scope mount off?
