Spud,

   I don't see any advantage to using LR primers in that small a case. Possibly of some use back in the early smokeless days when some shooters even used BP as a priming charge because the early smokeless powders were hard to ignite.

  When using the LP primers just be sure they don't sit to deep into the case. If they do then the primers will set back into the breech face, and in time will create a "pocket". If this "pocket" gets to deep it could interfere with opening the action, or in a worst case break the firing pin.

  The LP primer idea is good if the above problem doesn't occur since the use of a LR primer will probably be strong enuf to give varying degrees of push to the bullet before ignition get properly underway, which isn't good for accuracy.
