reloading 300 Black Out

I am starting with a RL550B set up to reload .223.  I use a new automatic powdewr system for each caliber that I reload.  I now want to load 300 black out, which is a 30 cal bullet in a cut doen .223 case.  My question is which powder funnel do I need for my powder system to cycle properly?  This case is short compared to the .223 case and doesn't want to move the bar more that 1/3 of the way.

Hi, you use the 7.62 x 39 (AK) funnel which is #13015. I'm going through the same process now, and just trying to get a hold of a trimming die for this calibre that will work with the 1200 Rapid Trim. Dillon don't yet show one as being available but Whidden Gunworks makes one.

I figured out that I needed a "AK" power funnel to make the automatic powder feeder cycle.  However, Now I am having trouble getting the bell set on the case where it will accept a .30 bullet.  I tried screwing the powder die until I crushed a case.  I backed it off some and no bell.  I screwed it back in gradually ahd dislodged and lost the little white square that cycles the powder bar.  I don't know why Dillon doesn't include a couple extra with each powder dispenser.  Anyone have a clue as to how to adjust the powder die/measurer (after I get another little white square) so that the case has enough room for the .30 bullet?

You don't need to bell the case mouth on rifle cartridges. I just finished reloading 400 rounds of 300BLK with my RL550B. Simply hold the bullet in place as you lower the reloading handle until the bullet is well inside the bullet seating die. Boat tail bullets will stand alone in the case but flat base bullets like the 100gr V-Max need to be held all the way up.

If you don't use one already I recommend the Lee Factory Crimp die for 300BLK if your rifle is semi-auto.

I really enjoy shooting my 300BLK AR--so much so I ordered a 300BLK Handi Rifle.

can I use a number 5 shell plate for 300 blk or a number 3 shell plate ?

Use a #3 SHELLPLATE, #3 locator pins and AK funnel for 300 Blk.
