I loaded Win 748 with 55 fmj bullets for a while and the main thing I would add is that it's temperature sensitive. I'd consider that load to be too "hot' for summertime temps. Some data sources list data for 55 fmj's at 27 grains or higher but most data is from 26.2-26.4 grains. I've found 26.4 to be safe in summer temps or when a round is left in a hot chamber in AR's. If you decide to pull those rounds I'd get a RCBS or Hornady collet bullet puller for your press. Definitely wouldn't try pulling that many with an impact puller. The collet pullers are fast and the powder is left in the case without any bullet damage. I'd also check the powder and reuse it making sure it's all the same, I'd measure all the case lengths, would remove the priming punch from the sizing die and partially resize the neck, and leave the CCI 41"s in the case. I'd also check that no primer was left high. My point is that I'd double check everything even though you trust your friend.
