I found old 16ga Auto-5: short barrel around 25" in length IC with 70mm chambers. The gun is in very good condition with some handling marks. While little heavy to modern standards (when compared to Benelli or Beretta) it is of all steel and wood construction. Is it difficult to adjust recoil spring to make it reliable and to prevent forend wood from splitting. What loads are recommended.
Are the standard US game loads ok (Remington seems most available) or should one stick with specialty loads from RST, for example. thanks.
