In the best of times a
375 Ruger ( not H&H) is a niche item , not commonly in stock with most FFLs .
There's wonderment about ammo supply Now ? Year , year & half ago shelves were all but totally bare of Everything . Currently the availability is good on popular calibers , and prices creeping downwards .
Of course , the mfgs have been concentrating production on the most popular calibers , and second tier cals gradually creeping back .
Primers are being occasionally seen again , but the gripes are now about the Prices . Dealers are paying high prices to jobbers , and " normal " mark up puts them +/- $100 / k . Powders are out there . Maybe not every single powder at every moment , but something suitable for just about every purpose . Sometimes the prices are jacked , but with looking around , can frequently find them at semi- normal .
Guns Shows can be very different , even at sequential shows at the same venue .
And yes , combat tupperware and tacticool accessories are in high demand from the buying public , and dealers are in the business of selling what the buyers want to buy .
Counterintuitively , * often* will be more variety at small shows than large shows .
