No there is no simple solution. It incorporates multiple variables to determine its value.
Your best bet is to use a ballistics solver that accounts for it. Its usually one of the smaller deviations on target.
People love the simplicity of defining one variable as most important, but it is just not the case. Its a combination of many variables that need to be applied appropriately. If you are discriminating any individual characteristic you are denying yourself the opportunity of education.
Im not sure a lot of these guys know how long Kirby has been doing this.
When I first got into LRH in the mid 2000’s Kirby was already well established as a source of fact and was playing with some BIG boomers.
Pretty much everything many of us learned came from Shawn Carlock and Kirby...
I use a spin box with paper every increment of what your twist should be.
Mark a bullet with a marker and fire it through the box. The tick marks will tell you how far off you are.
If you really want to get particular, measure the spin on the bullet after it leaves the barrel.
If a barrel twist tightens up, loosens up, or gets worn at the last couple inches, this is what is gonna determine the spin imparted on the bullet.
I have a NF Beast Id like to trade for a Khales 525i MOA
Scope is in good shape. Sure it has a scratch or two and im sure there is some wear on the allen heads, but overall is in very good shape. It has a MOAR reticle.
Would like to trade for a Khales 525i or a S&B PM2
Its worth considering how much metal you are taking off, as well as how much you are leaving on.
If you cut a small thread on a thick barrel the crown will often open up .0001/.0002”.
The crown is not a good place to do that.
Also, any machinist worth his salt will tell you minor diameter on...
Believe it or not, no not so much.
I still dont care to shoot 100 yd targets, but with the newer class of scopes with much closer/finer parallax adjustment. My 100 yd groups and zero are way more consistent to my long range data.
Pretty much a non issue these days.
I think Grey Fox has some really good points to consider here. I think he pretty much hit on the major contributors to learning/managing follow through.
I personally think its all about recoil. The more you have the bigger the problem.
No, you are good.
The reason you are getting a good deal on a good brake is because its a small shop that works hard. If he spent a bunch of time on the phone or paying for a really great site that is gonna tack on to your cost, significantly.
Muzzle brakes are a tough business.
Ive never seen anyone use a scope checker for a tracking test, but i dont see any reason it wouldt work.
It basically gets you out of rigidly mounting the optic because the primary optic can be used as your reference point. Good idea.
I also hang a scale very similar to picture you posted. It...
