I have a model 20 in the 284 winchester...

It has a #2 taper and I prefer it to a #1 I have models with both
tapers...douglas barrels get a bad rap here but it WILL shoot regardless of what others will say and Melvin will stand behind it...THEY SHOOT with all the other brands of barrels I have

As far as brass bullets.com has 284 brass made by Norma....buy all you want if this is what you want and be happy.....
