Mikecr, I like the images of your neck sizing set up. I see how you can control and test the length of neck sized with spacers in the Wilson arbor dies. I have been using the Wilson neck sizing dies with my 300 Win Mag for years with good results and very little run out. I believe that the...

Back after a few days at work....Several thoughts to the above questions and comments. I have not tried to shoot any similarly prepped and sized rounds on target yet. I have just been experimenting and troubleshooting my set-up. The purpose of my experiment was as much to describe my setup so...

Mikecr and Tiny Tim, I agree with both your comments. What we are commonly calling neck tension (NT), is technically termed hoop tension or hoop stress. It appears from my understanding that we can’t, or at least can’t easily, measure hoop tension. Therefore we are measuring NT as a surrogate...

INTRODUCTION: I recently completed an experiment that I thought many of you might have an interest in reviewing. After reading many of the posts on LRH (https://www.longrangehunting.com/threads/mandrel-as-last-step.258463/) and Hammertime...

Nice rifle. Looks about similar in size and weight to my Rem 700 Sendero in 7STW with fluted 26” SS barrel with 1:9.5” twist (if memory serves). I believe mine weighs about 9 lbs bare wt. Great rifle and great cartridge. Mine is a little heavy to hike around mountains with, but great long range...

Two quick questions: 1. Bore Tech Eliminator and several other products say they will not damage the bore if left in the bore, and will also serve as a rust preventative. I am a little old fashioned, and have always removed it once done and then oiled the bore. Has anyone had any experience...

SHORT TERM: Bore: Butch‘s Gun Oil SS and matte steel: Rust Prevent (penetrates well and dries well without leaving tacky) Bright blued steel: Boeing T-9 Hoppes gun oil on a rag for all quick touch ups LONG TERM (yrs): Bore: RIG Metal Exterior: Brownells LTS (dries to a hard coat) I use...

Zen, I watched your video and read the thread. Please take my comments with the kindest of intentions and most respect, as I have enjoyed reading your posts on the forum and am not aware of all the components in your system. Just a few thoughts: 1) I am a little concerned with your pierced...

Steve, Thank you for the information and discussion. The history and your findings along the way are very interesting. Thank you for your willingness and openess in discussing your bullets. We all appreciate it and can learn a lot. Best wishes. Mike D

PART 3/3 - THEORIES AND QUESTIONS FOR REPORTED OBSERVATIONS: Here are some thoughts, along with some questions for Steve from Hammer Bullets, regarding the discrepancies in theories between powder charges / types, pressure, and velocities for the Hammer-type (mono-core projectile with driving...

PART 2/3 - DESIGN IMPACTS ON DTL, PRESSURE, & VELOCITY: The Hammer Hunters are more similar to traditional bullets than the Absolute Hammers in that the ogive tapers to maximum diameter (0.2770”). This means that the ogive portion of the Hammers will contact the leade (tapered initial portion...

ADDITIONAL THOUGHTS ON HAMMER BULLETS, PRESSURE, AND VELOCITY (3 parts due to figures): PART 1/3 - DESIGN AND FORM COMPARISON: For those that have not looked at the Hammer Bullets up close, attached are images and an explanation that may make the differences between the Absolute Hammers...

This thread is very interesting, and contains much good info and theories, along with a lot of conflicting thoughts. I've started working up some loads for a 270 Wby with Absolute Hammer 116s and Hammer Hunters 117s this week (perfect timing), so I have been reviewing my reloading notes and...

Local JW. You can use either a FL die without a bushing or a FL die with a bushing small enough to reduce the necks a sufficient amount. A FL die without a bushing tends to reduce necks more than necessary at around 0.005-0.010" -- you can measure this for your dies and cases by measuring the...
