I believe the original intent of the Lee Bulge Buster or the G-Rx push-through resizing dies was to use them once to resize the base of the case that regular resizing dies could not reduce. Then to use the regular resizing die for subsequent reloadings. For me, the OCD makes me toss/recycle cases I cannot resize with the regular resizing die and the single stage press/shell holder. 40S&W is the most popular case I pick up at the range and it's easier/faster to toss the case than to push-through resize in the FCD.
If your powder/charge loads are continuing to bulge the case to the point where Bulge Buster/G-Rx need to be used repeatedly, I would be concerned and reduce the powder charge, change to a different powder or use a tighter chambered barrel so the brass won't bulge so much and decrease the chance of weakening the brass.
People have asked/PMed about me using "faster burning" W231/HP-38 and 40S&W with mixed range brass. Mid-to-high range load data of W231/HP-38, when shot in factory Glock barrels, slightly bulge the cases that are readily resized with the Lee resizing die and pass the drop test in tight Lone Wolf chambers. I have shot near max/max load data of W231/HP-38 and other slower powders (WSF, HS-6, Universal, Power Pistol, Unique) but prefer to shoot them in tighter chambered Lone Wolf barrels that will not bulge the cases. Spent cases from LW barrels will resize with very minimal effort on the ram lever. I have reloaded a test batch of once-fired brass using mid-to-high range load data of W231/HP-38 in LW barrels and stopped the test after 50+ reloadings when there was no case failure or case neck splits.
Regardless of the powder/charges used, bulging of cases should be one of many indicators for reloaders to check the power/charge/chamber size. If the bulges are excessive to the point where the use of Bulge Buster is required repeatedly, I would be concerned and make some changes.
If your bulges can be reduced with the regular resizing die, I would adjust the powder charge so I get accuracy and reliable slide cycling with the lowest charge to minimize the bulging.
If your pistol chamber is tight and you do not get bulging with published load data, look for the usual pressure signs and shoot away!
