The groups so far have been lack luster but I'm shooting Remington Core loks.
I've come to the conclusion that the trigger on the Winchester M70 sucks donkey balls. I'm super pissed about it. I had it smithed down to 1 3/4 lbs. The problem is that depending on where you put your finger on the trigger you get a very different response. Essentially if your a bench shooter I'd wait till there are some after market triggers out there for this rifle. Otherwise if you're just a hunter this may seem like the best trigger you've ever sampled on a factory gun. For me it sucks.
The best groups I've gotten so far are around the 1.5" range. Right now I'm just fire forming some brass. In the next handful of weeks I will be getting down and dirty with some nicer bullets and different oal cartridges.
One thing I notice right away is that this light weight barrel gets really hot. Like three shots and I'm on a 15 minute time out.
I will report back over the next couple of weeks.
