With your ".660" depth, what is the stick out dimension from the back of the rim to the barrel or from the front of the rim to the barrel?

Thanks, I will contact him.
I talked to Neil and he hasn't made the Hunter class loupes in years and I don't they had a 224 ring in them either which is what I was looking for for RF.
Where can I get a NBRSA scoring Loupe?
no

I used an interference thread fit acetal adjustment barrel to eliminate minute adjustment variations. Unfortunately, it acts like a solid lockup tuner that is peaky.
The new tuner design was a complete success in one aspect and an utter failure in another aspect. Oh well, good thing I only built one.
I have had better luck with polygons over the years. In benchrest, the thinking is you want the slowest twist that will stabilize just enough to get to the target. 14 twist used to be the norm in...
The barrel would be a properly taper lapped, R5 or possibly a reverse taper contour, polygon rifling 16.25 twist. The trigger would be a Flavio Whisper, set sub ounce. Tuner of my own design. The...
Phil's single agg was 2491.67. I think you mistyped. I don't know Phil or anything about his rifle. The rumor was that he shot it with the identical lot of Midas+ that Chuck was using at the time....
Records: For a single 6 card agg I believe it is Phil Dorman's 2491.67. The nats are a single 6 card agg. For a season, it is Chuck Morrell's 2403.7162. Depending on your criteria for determining...
I hesitate to name specific numbers as they are often mistaken because of variation in measurement methods. Lead is quite easily deformed. Each gunsmith will have his preferred chamber depth. When I...
An important dimension is the amount of bullet engraving when the bolt is closed which is dictated by how deep a rimless reamer cuts the barrel. There are several depths that work well with Eley and...
How about the eyepiece cover? Size in Sensei Brand for SIII 10x50 pwr?
Never mind I found it. 8AM-2PM
Butch, What is the time frame?
Sold
I believe it is changes in acceleration rather than velocity that is more critical in exit timing.
JB is way too fine. I use Clover 220 grit on an Iosso plastic brush.
I use 25 foot pounds.
the top one is the more centered plug with the ten ring
Here are pictures of 10 shot groups, shot with 2 new barrels that Jerry Stiller lapped and I chambered and cut to a very specific length. I think the lapping is critical on how well a barrel will...
The first one is what I have.
