Anyone have any tips on how to deal with loading a compressed load on the Dillon RL550?

I posed a question earlier about the .223 Rem. and difficulty of maintaining bullet alignment for seating with the powder at or above the rim.

Anyone have any success with this - any "tricks" to get the powder to compress and fill the case better prior to bullet seat?

Thanks, Wayne

on a SDB and on the hornady LNL AP, i would NOT NOT NOT use compressed loads.. loose powder screws things up on timing.

my advice, change powder

Sorry - but I am not familiar with these terms.
Could you explain them for me please.

the abbreviations are for the hornady pr dillion progressive presses. what jeff is telling you is not to try for compressed loads on a progressive press. I'll strongly second that. there is no decent was to get more than a 100% load without shaking, vibrating, long drop tube etc, and on a progressive press any of these will mess up the operation. if you want compressed loads do it on a single stage press. if you want the progressive press advantage, then change powders to something a bit faster

Now I understand - thanks.

I did not want a compressed load per se (actually never had one before). It is just that the 4350 in thie .223 Rem. in this particular Mini-14 was really accurate.

I guess I just have to play some more.

lots of tight tolerences moving precision .. loose powder roaming about jams and breaks things.

Thanks Jeffeosso - I was noticing that with the loose powder granules.

I backed it down by 0.2gr. and changed the seating depth and this seems to work well now. Will test it out at the range. Wayne

The only way to get compressed loads to work is a longer drop tube. That means charging th epowder by hand w/ a drop tube/funnel. Yes it will be slower, but it will work. I would just try a ball pwoder. W748, BLC-2, AA2520, H322, H335, etc, all will work well in the Dillon.
