Have only reloaded for bolt actions in the past, but may start doing some 284 in a winchester 100 semi auto. What are your thoughts on using small base dies. Are they needed or just stick with the regular full length sizing dies?

Thanks

  i got yet another case stuck in my rcbs dies tonight. this time managed to get through about 25 cases befor one got stuck. these were lubed with the roll pad again and a q-tip with the spray lube stuck down the neck. im reloading these to shoot in a bushmaster xm15. are small based dies required for loading in all semi auto rifles? could using small base dies be the reason for all the trouble im having? i just tried calling rcbs as i didnt see a email on their website and there closed till monday.

  Does anyone even make a SB die for the 284?
  I just looked over the RCBS SB dies at Huntington's, and they don't show one.
  
  Personally I'd try it with standards, than order a SB only if needed.

  I never used a SB die unless the brass 223 mostly had been fired in machine guns.

  I have never reloaded A rebated rim cartridge I would think normal dies would work .

  I had also never seen a SB die in this caliber, RCBS does not list one on their site. Just seen where one was advertised on another site and thought I would get input. Have asked the seller for pics of the die box (would like to see the RCBS number) and die to see if it does have SB on them.

  Small base dies are great in AR's as the bolt carrier rebound is not real strong. I don't know how it would compare to the Winchester 100. If your ammo works fine the way it is I'd just leave it alone.

  wolfpack,
  
  I suggest that you give some a try first before trying to make any decision about spending money unnecessarily. Based on the reloading I've done for the Win. 100s, I don't think that you'll need the small base dies. However if you do for some reason Midway, Sinclair and Brownells all carry the Redding Small Base Body Die:
  
  http://www.midwayusa.com/Product/377176/redding-small-base-body-die-284-winchester
  
  This is a body die only and does not affect the neck but bumps the shoulder.
  
  Best.
