OCW opinions...?????

.035" off lands looks the best group.
Any registered bad call?

Ok.... just got back from the range... I loaded up 45.5gr and seated bullets at .005" to .075" off the lands.... I can't say I'm not happy. There were a couple I made a ---- shot but there is a couple real decent groups, granted it's only 3 shots but it looks pretty consistent.....thoughts?View attachment 131140

Here's the order guess I should've stated this.... it goes from furthest to closest

3rd & 5th group had 1 flyer....

 

[Echo Charlie]

forgiving the flyers on .055 and .035 groups and with a nice group in the middle I would go on .045" off lands or confirm with finer COLs on that range

 

[User4302021]

Depending on the flyer in the fifth group, .045, .035, and .025 could all look good.

 

[Kampfjager]

I'm gonna load up some at .045" & run out to 250y and see how it holds up, I'll post results asap...... gotta say I'm pretty proud of the rifle, especially since it's a 100% factory barrel and action!

Here's groups measured..... and labeled (using "moa" loosly)...

That is looking great! I agree with the several options for seating depths. All in all you have a great load. Now to get your velocity and build your charts!!

I wish I had fewer activities going on this spring. So many things going on that prevent me from range time...

Here's a question, if you allow the barrel to cool between each group during an OCW test ,is it necessary to shoot it round Robin style? What's your thoughts?

What sucks is that OAL won't fit in the magazine.........

Load to maximum magazine length and reduce that col in increments.
May be you can get a col that groups similar to those.

This is one aspect of the prescribed OCW that I ignore. If I was shooting a bench gun off a benchrest, I suppose it wouldn't matter.

But for a person shooting the way normal people shoot, the constant changing of position adds in more variables than you are theoretically eliminating. Consistent body position, cheek weld etc. are far more important than a few more rounds worth of fouling on group sizes.

So you don't shoot it round robin?
