RE: The Eternal Debate : MOA or MIL

@treeman That should not be the sole parameter for selecting a scope. There are other more important criteria to be met, which if satisfied, make the angular measurement incidental.

Weight of the scope, reticle type, objective diameter, tube diameter, glass quality, light transmission, illumination, built in range finder, capped, exposed or lockable turrets, warranty - these should take precedent over MIL or MOA.

So ! If I were to buy a scope tomorrow for long range hunting - mils or MOA

I do not know anyone that can look through a scope with a plex reticle and geustimate inches with any degree of accuracy so MOA and inches does not track. With a graduated reticles you measure in angles, not distance. MOA and mills are just different angle measuring systems. Provided all use the same system and the turrets and reticle is the same system, there can be no confusion. Secondly, using mills does make it easier to calculate ranges for known sizes, and sizes at known ranges, except nobody shooting does that. Lastly, since I have started target shooting I have learnt to think in MOA for wind and range adjustments, so now I am too lazy and old to retrain my brain to instinctively think in mills.

The Eternal Debate : MOA or MIL

I'm not understanding what the kerfuffle is all about.

One is not better than the other.

In both cases, any scope adjustment is going to require calculation.

I use a MOA scope, range in meters, and use meters in my ballistic calculator. I don't need to do math in my head, so the units of measure are just numbers to the calculator.

Ranging in yards and using a MOA reticle makes it easier to mentally quantify an offset, and the same for ranging in meters and using a MIL reticle. In cases where the target size is given in cm, but not the range, it makes the mental gymnastics less challenging when using a MIL reticle. Same for inch size targets and a MOA reticle.

Interestingly, scope bases are never classified in MILS of elevation, always in MOA.

Copied from Gunsite as I think it is appropriate for handgunners.

RE: Truvelo 12.7x99 firing pin removal

When I am too lazy to remove firing pins, with a sized case in the chamber, I keep the trigger depressed while slowly closing the bolt. If the spring tension closes the bolt all the way without any pressure from my fingers I know the die is set for approximately 0 thou headspace. I then size 2 thou more from there.

Truvelo 12.7x99 firing pin removal

Works like a Shultz & Larsen.

I've owned this rifle for a year or so, and I was never confident that I was sizing the brass correctly. Because I didn't know how to remove the firing pin, I worked on a go, no-go method. This was done using a fired Berdan case that would not chamber at all, sizing it fractionally till the bolt could close.

Sized a batch of brass today, and I tested the bolt close on a sized case, compared to a fired case from this rifle, to see if I could feel the difference, and I could not with any degree of certainty.

I had searched online for info several times, unsuccessfully. Today I included 4-lug bolt in the criteria, and Halleluja !

My go, no-go method with the firing pin in the bolt is very close, it needs a partial hair less to be where I want it.
