For years all I've ever used were standard dies from RCBS, Lee, Redding, and Hornady. I've never had a problem with these giving me consistent accuracy and velocity. Bushing dies give you more control on neck tension, which can improve your accuracy and consistency. I don't think bushing dies are required for 90% of shooters and hunters. A lot of guys use them because they give you the ultimate control in sizing and many feel they're the best on the market.
One thing I have found that's considered as good or better than bushing dies, is using a Sinclair mandrel die. The die is like $35 and universal, and you can buy the mandrels for around $15-20 a piece and they are .001 or .002 under bullet diameter to set your neck tension. 21st Century makes them that fit the Sinclair die and they're in .0005 increments. They take an extra step, but I don't mind. I haven't yet completed my testing on them, but preliminary results look good. The bullets seat with more consistent and better feel. And the limited velocity testing I did and runout testing showed the mandrel sized cases were a little better than just standard sizing dies.
