My BF is about 10 years old and still shoots extremely well. Chambered to .25-20 WCF, with 87-grain Speer TNT bullets it will consistently agg 0.5 to 0.6 moa for four, 5-shot groups. It wears an older Simmons 2.5x7 scope. This barrel was supplied to them by Bullberry - I don't know where they get their barrels today.
