300 Blackout Cases

Hi everyone,
I am thinking (boy that gets me in trouble) of picking up a 300 Blackout AR. I was looking at what it will cost me to outfit my 650 for it. Its a lot! I have the 1500 case trimmer and was thinking of doing it in stages. I would need to spend some time converting some 223 brass to 300 Blackout brass. My question (you were hoping I would get to it I know) is can I use the caliber conversion kit I have for the 223 as I feed it into the press to trim and form them to the 300 Blackout? This way all I thing I need to buy for this part would be the new trim die for my 1500 trimmer (wow those are 170$). I do not think the case would feed into the press again after its trimmed with the 223 parts but it would allow me to work on trimming a few hundred cases and case some bullets.

Thank you for any reply's you send my way.

You are correct, as the cases feeding into the shellplate are .223. They aren't 300 Blackout until they eject into the bin. Even after converting, for the conversion kit you will only need the 22 Hornet case feed adapter and the AK powder funnel.

Thank you

I went into your website and found the powder funnels but it did not list one for the "AK powder funnel" Can you give me your number for the one I need for the 300 Blackout please.

Thank You again, With that number I was able to get both parts I needed ordered from your website just now, I also got some more case lube.
