I was practicing with my 375 Ruger for my grizzly hunt this spring. I would only take about 10 to 15 shots at a session. Anything more than that I would start to flinch. Sometimes it didn't even take that many to start flinching. I killed my grizzly in June now the Hawkeye sits in the gun cabinet. Maybe a Aussie Buff hunt is in the future until then it will just collect dust. Bob
