Thanks for the input. I loaded another 150 for FNS and encountered the same problem. I am using Lee dies with the following specs:
230 grn Powerbond bullet
4.6 grns Titegroup bowder
1.250 overall length
I ran the rounds through a Springfield TRP and I've never had an issue with any rounds in the past. I checked the powder and length throughout the process and the crimping was smooth.
I will try taking the length to 1.200 with 4.6 grns of Titegroup and also running the current length of 1.250 with 4.8 grns of Titegroup. I'm hoping the adjustment in the length will solve the problem.
Not familiar with that bullet. Is it a FP or RN ? I usually run the FP at 1.200 and the RN at 1.260. If that is a RN, watch for the spot where the ogive starts. You don't want to go beyond that and have the case edge on the radius of the ogive. Again, I'm not familiar with that bullet. Going to 1.200 might not be a problem at all. Just kinda seemed a little deep if a RN.
If that Springfield runs fine with factory, you will find what works for it in short order. Keep it up, you're probably not far from finding in now.
