IMR 4320 - .223

Re: IMR 4320 - .223

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: former naval person</div><div class="ubbcode-body">Probably because of the large stick size and the small neck. Bridging is a major headache with that combination. The ball powders flow so much better in that configuration. JMHO </div></div>



Varget is even worse in my eyes.... but everyone loves varget...
 
Re: IMR 4320 - .223

I guess a lot depends upon the measure. I ran some tests with a Redding, a Lyman, and a Dillon. With 4895 or Varget they all were within +/- .2 gr. With RL 19, the Redding and Lyman were the same but the Dillon would bridge about 3 time out of 5. Interesting, but frustrating.
