Hi, I am new to this site and find it very informative. I have been reloading for about 7 yrs but just for my revolvers. My friend has asked me to help in reloading for his new Ruger P90 in 45 ACP. My starting load is 165 gr rn lead and 7.5 grs of HP38 powder. The ammo works well except for intermittent jams on ejection. It seams that the ejection clip is not going all the way in the grove of the casing and causes a slight nick in the base. Both the bullet and casings are from Mid-way Supply who are great people to deal with. It also happens with factory ammo but not as bad. I messured both casings and both are equal in length. We are loading this lite load for our class we will be taking from Rochester Personal Defense next weekend here in Binghamton NY. I hope someone will be able help me with this problem.
