Is the March FX 4.5-28x52 my new ZCO?

Long range update. I took the Tikka with the March 4.5-28 out yesterday. I think more tracking tests need to be done when I have better load data. I did have a dialing discrepency however I believe it was a data and shooting angle issue rather than tracking. Time for me to pick up a cosign indicator as the shoot involved shooting up and down at angle.

What I can say for sure is that the glass is stellar, really world class. I could clearly see very defined hits, splashes, where the steel was blackened from impacts very clearly. I would venture to say that next to the SnB 6-36 that was out there yesterday the March had the best glass, the SnB 6-36 edged it out but only slightly.

Leveling a scope is dumb

reticle to level to gravity = rifle is level.

the only caveat is if your reticle isn't square to your erector.

then you're screwed...:ROFLMAO:
I've seen a few scopes where the reticle wasn't plumb and square with the turret knobs or any other flat reference surface on the scope body. In each instance, I ran tall target test which verified the erector and crosshairs were plump and square to each other. The erector was not square to the scope body.

In instances like that, you just adjust your scope level to be true to your crosshair plumb/level. Forget about referencing anything to the scope body or turret caps.

Why do people make this so hard?

Because the scope cap isn’t 90 degrees to the reticle, and because we spend a lot of time and money trying to be accurate out to far distances.

Help with fire forming

Ok so I have a question to this then. With the shoulder bump gauge the improved brass measures out at 2.111 and the normal is at 2.020. Isn’t that way too big of a jump? If I’m working up two loads to just shoot won’t I have case head separation?
Nope. I have done this in 2 rifles. It's the shoulders angle that is being pushed out, not the actual shoulder, so you can shoot both fine.

6cm and the bullet unseating

The bullet is jammed into the lands when you close the bolt. Opening the bolt pulls the bullet. Usually factory ammo has enough “neck tension” that this doesn’t happen. Also, usually factory ammo is seated short enough that the bullet is nowhere near the lands. It’s a lawyer’s nightmare to have a customer call with a complaint that the bullets are jammed into a factory barrel so they tend to seat them on the short end of the scale. In your case, I’m guessing the prefit has a really short throat or is headspaced incorrectly such that the bullet, even at short factory seated length, is much farther forward in the chamber than is normal. It is possible, but unlikely in my opinion, that a lot of carbon build up in the throat could be causing this. Are there any other signs of irregularity? Pressure, hard bolt close, hard open, pierced primers, etc?
I had a couple times where it was hard to close the bolt, yes. As far as pierced primers, no.

After Hugo I went to South Carolina with a group to offer aid. It was truly a devastating storm there.
I got volunteered to repair distribution powerlines in my state of North Carolina that were damaged by Hugo. We worked the rural areas near Albemarle. I specifically remember the name of one community, Frog Pond. :)

Exactly what I use. Attach scope base ( I like the Talley Lightweight system ). Level across base, make the barrel level match. Add scope, level scope to match barrel level. Done.

6mm ARC Gas Gun Barrel Lengths and Muzzle Velocities

Thanks for the responses! I've already reviewed a lot of old threads both on the "Hide" and elsewhere, and gleaned some worthwhile information from them, but not quite what I'm looking for. In addition, I've looked at bullet and powder manufacturer's charts such as the one that WeR0206 posted...but again, with the same outcome. I'm looking for real world 6mm ARC gas gun muzzle velocity data with 103-grain ELD-X tipped handloads fired from 18" and 20" barrels.

I currently have a custom 20" Bartlein (0.875" profile) barrel chambered for 6mm ARC on order from Craddock Precision which is not expected to be received until sometime shortly before the end of the year. A headspaced bolt will be received with the barrel. And like WeR0206, I too have already acquired 100 pieces of new, Alpha brass for future reloading operations. Meanwhile, I've been vacillating back and forth for some time on whether or not I should change the order to get an 18" barrel instead of one that is 2" longer. I'm hopeful that I'll be able to resolve my dilemma with the receipt of the desired information.

Based on what little information that I have been able to find on-line thus far, it appears as though a 6mm ARC handload when charged with LeverEvolution powder will propel a 103-grain ELD-X bullet with reasonable accuracy from an 18" barrel at about 2,635 fps and approximately 2,685 fps from a 20" barrel. However, I'd like to acquire and review more such data before ultimately making up my mind on this matter. I'm having trouble reconciling in my mind wether or not the extra 2" of barrel length along with an additional 50 fps increase in muzzle velocity and some extended range capability will be worth the added transport weight and some anticipated decrease in maneuverability of the rifle while hunting coyotes and whitetail deer.

So, with the new tariffs…..

So tarifs, DJT just did three nearly impossible things at once.

(1) protect tha American worker from unfair trade practices of our partners.

(2) Begin rebuilding American manufacturing.

(3) Find a tax Democrats don't like.
Yes because every American’s dream is to work in a sweatshop to make tennis shoes for 10$ a day in a 110F factory with no HVAC.

.308 Winchester

If you set up your rifle to take the correct detachable mags something like 2.990" MDT minus center plate, will feed through a standard Rem short action...available on line everywhere.
With a little inletting on your part, presto you too, can have the same setup.

This will help with the 200 gr and heavier to seat out past the ogive.
These are 208 Bergers at 2700 fps in $600 rifle build with a new Bartlein 5R 9 twist 22" barrel, bottom metal, magazine, and muzzle brake ....used parts on a trued Rem 700.
The rifle was a previous factory Rem LTR, with a shot out barrel.
I've got a couple Alpha mags that'll take COAL's of that length (2.979"). But I don't know if Alpha is still doing business or if there are suppliers that have them???
