I have shot many PROOF and Bartlein carbon barrels. I have no experience with benchmark or other companies due to my preference in how the barrel is wrapped and how the wrapping of a barrel affect heat movement from the SS core.
To date, I have shot somewhere in the neighborhood of 18 to...
My understanding is that it is 6 months for all licenses and applications. Once you have a resident license after 6 months, it applies for all applications.
RL26 has been unobtanium for quite some time however the Vhit powders are seen more frequently.
7 PRC should run in the 565 to 568 burn rate pretty well and give plenty of velocity. 570 is going be a lower burn rate and tends to be very fast but pressure and throat erosion can be an issue.
I...
You are looking at a gently used pair of Leica HD-B binos in popular 10x42 configuration. The technology used outshines anything seen before and consists of an outstanding integrated ABC® ballistics function and a microSD card in combination with an entirely new optical concept.

It could...we are chasing some phantoms right now but if your brass is expanding a lot and the headspace is long, it could lengthen the case and cause pressure e.g. clicking.
You don't want your brass to stretch and expand too much. I use about a .001 to .0015 bump usually. .003 may be a bit much
It appears there is a significant expansion of the brass in picture #2 that could be due to headspace.
Headspace is the distance measured from a closed chamber's breech face to the chamber feature that limits the insertion depth of a cartridge. Headspacing refers to the act of stopping deeper...
Agree here. Trying to polish a chamber by hand is a difficult proposition.
I would first try to clean it as much as you can, and I mean clean it. Completely
I would not attempt anything else until you do that - after you are 100% sure it is fully clean, clean your fired cases completely and...
This makes sense. Any time you are working with a larger case capacity and a bigger bullet, slower burn rate powders will usually maximize your velocity and lower pressures. They are also less "snappy" with recoil.
A burn rate chart is always good to have around
An XM action will give you a lot of options down the road too...since you are going with a 540 bolt face it will allow you to change barrels and maximize your mag size with many of the new caliber offerings. (if you wanna go 6.5 PRC) I do like the option of the 3.1 Wyatts box but if you get the...
All good recommendations - keep in mind if you intend on making any changes to that set up, like perhaps a lighter carbon stock later on etc...for actions like the Tikka and a few others, since they are not designed on the Remington footprint, finding Tikka specific components and things can...
Since you already have a 30 cal, my vote would be for the 7 saum - can still run a fairly big bullet without giving up too much case room and if you built it on a lightweight medium action, you can really maximize that cartridge a lot better.
If you are going to go full custom, you can easily...
