Varmint Al's models address the cantilevered-beam approach to describing what happens with a barrel when a gun is fired. My opinion is that this is more useful from a gun-handling and bench-bag-setup perspective than it is as a discussion of tuner dynamics. This is especially true when you try...

Mike, your use and methods very much mirror what I've discovered and practiced since starting with Gene's tuners in 2008. I'd like to re-enforce your message that computer simulations are NOT results. I've had dozens of discussions with arm-chair accuracy experts who can quote every frame of...

Ah Gene! That's what I've been telling you for the last 6 years!! Now to add one more part of the myth to break: The 'absolute' position of the tuner ring (zero-up, X turn(s) off the shoulder) is only useful with respect to that set of tuner rings and the individual barrel. Because barrels...

I've promised Audrey another article for Precision Rifleman magazine... this one will describe how I analyzed my tuner settings in an Excel spreadsheet with instructions for anyone to do the same. Probably fit it into an issue later this season. Rod

I've found that my PPCs are pretty predictable in temperature ranges from about 30 to about 97 degrees. But outside of those bounds, the small incremental changes I normally make with either tuner or powder measure don't seem to have the same effect and I have to work to find an optimal tune...

Jeez -- I love a LIVELY tuner discussion! New tuners for me this year (sorry Mr Begg's) -- my new-to-me Nardini lathe won't cut a 28TPI thread, so I had to move on the 32TPI. Made a new set of knurled rings (ala Ralph) for the barrels I doing this winter. I've gone full circle a couple times...

Check which version you are getting... Audrey has had the official NBRSA calipers made by Neil Jones in the past. Some recent calipers I've seen (like the new version pictured in the Sinclair catalog) have aluminum sliding plates with half-circles cut for each caliber... tolerable for...

I'll be running a tuner again next year. I was doing a lot of testing different components and equipment this year -- NF and Marsh scopes, LT powders, and three barrels that I bought lightly used. The barrels were shooting well, and they were too skinny on the muzzle end to thread for my Beggs...

My Powell has a V-block design. I cut three long, narrow strips of that 10-mil PVC tape to serve as a buffer between the barrel and the block at teh three points of contact. This has worked very well for several different barrels that varied from 1.450 down to 1.350 and even a bit smaller. Rod

A Colorado shooter built a very competitive railgun laminating layers of 3/4" Baltic Birch plywood. Gun with barreled action still came in around 30 pounds total, I believe. I don't know the magic that seems to become part of some rails and not others but when a gun has that magic, it is...

Sorry Richard about the 'opposite' thing... like you, I was just offering an alternative viewpoint to the previous posts that mentioned using the gunsmith's reamer. Rod

Opposite of the above... one of my recommendations to any new shooter who is serious about being competitive in short range BR: wear out the barrel the comes on your first rifle, but buy your own reamer before you start buying more barrels or other knick-knacks. One of the biggest factors in...

Loose pockets are my usual way of determining when to retire brass. I typically shoot in the loads on the lighter side (27.9 to 28.3 of 133), and even then many firings will eventually loosen the pockets. Hotter loads definitely accelerate the process. I know a few shooters with pass-through...

Mike Ratigan uses a fluorescent pink vs white vane on his flags. I talked to him about it once, and he cited some research into how our eyes work and which colors are most visible and provide the maximum contrast with the grass/berms/background. I've shot over them and you can see them very...

Lps 1-2-3 There is a line of lubricant/preservatives called LPS in a blue spray can at many hardware and automotive supply places... I started using these after learning about them from 30's and 40's airplane restoration projects. The metal in these planes (old Cubs) is highly susceptible to...

Oops on the results... I'll post more better pictures at the next stop... we're rolling down a rough I-80, headed for St Louis! Rod

Larry White continued his domination of this range by taking repeating last years feat and taking home the Firewalker 2-Gun, as well as the three and four gun trophies. Newcomer Jeff Anderson from Billings MT in only his fourth match since being seduced to the dark side of Benchrest in July...

Hi Calvin, Paul and I are already getting tuned up for the Nats... shot Billings last weekend, shooting Porcupine and the Firewalker on the way there - we've been looking forward to this since Holton last year. Looking forward to seeing you! The way our yo-yo stock market is behaving, the...

Perhaps the variety (and probable validity) of all these suggestions should make make you ask another question... instead of abandoning the xxx (powder of your choice) because "it won't stay in tune", maybe you need need to re-examine your expectations and accept that load/tune changes are a...

I had the exact same experience as Richard over 5 years and 8 barrels equipped with Beggs tuners. 27.9 gr of N133 behind a half dozen different bullets at hard jam. 10 degrees to 105 degrees, Phoenix, Raton, Grand Junction, St Louis, and a lot of ranges in between. Dial-a-Group-Shape. Using an...
