Re: problems loading 7 STW
Maybe there are a couple of things to look at here.
The information that dakor pointed out is correct. Alliant has had a couple of runs of Re-22 that are more than just a bit fast. One lot had to be recalled and customers were compensated with a new lot number.
The information that you are going by from the Alliant website is tested and written for the 150 gr. Sierra Spitzer Boattail bullet, not the 150 gr. Scirocco. The Scirocco is 0.175" longer than the Sierra SBT, so that when they are loaded to the same OAL, the Scirocco creates more pressure since it takes up more space in the case.
I usually have to check and re-check loads that I find to be interesting on ReloadersNest. The ones that appear to be hot generally are very HOT! It seems like some of the folks that post loads there are still in the juvenile stages of "beer muscles". They want to post the hottest and fastest loads as if it is some sort of competition. On the other hand, I have found loads printed there that come directly from the Lapua and Norma reloading websites, exactly. Someone just copied them over to ReloadersNest and took credit for the load information.
This is just my opinion but I think that you will be better served by using a Magnum primer with these slow, bulky powders.
It might be interesting to measure the necks of a few re-sized cases; inside, outside and wall thickness in a couple of different places. Then compare these numbers with measurements from several fired cases. Measure your expander ball as well.
If I am remembering correctly, the people that I shoot with are using V V N-170, Re-25 and Ramshot Magnum in cases with capacities running in the 95 gr. to 120 gr. with magnum primers.
Best of luck! Post back.
