The early MC barrels had a flange on them that was 1.4" or so in diameter. It was rather short, just enough to widen the shoulder for support. It tapered quickly down to 1.3" dia or so, not sure. After 2018 I think, they switched to another barrel contour which is similar, or the same, as the...

You might have trouble differentiating between the lands and grooves smaller bore barrels are gonna be tough to reach inside barrel curvaturwill be n additional challenge

Sir- can you expand on how you calculate beamwidth at a certain distance using the known beam divergence info? thanks

I believe the BB steel was mill run lots (heats) and therefore were large batches. First serial number pre-fixes were 1BB, we saw this for the first couple years (?). We’re seeing serial numbers with 2BB now which implies to me that they have another lot of steel. The barrel I got was a...

Measure the case head diameter. There are variations in the 6.5x55 Swede. Check and see if your brass goes into, and falls out of your bolt face , with ejector removed some mfgs make it a 308 sized head, but it’s actually a little larger. Some bolt faces/heads have the additional clearance for...

The description is incorrect- it will work for right or left I’ll fix the description tomorrow

I’m 99% certain it will work for both right and left we did eventually make a line item on the site so they are available now for sale

The 7-6.5PRC was likely conceived due to the issues with the 7SAUM brass AND its availability. The 7-6.5 runs a little slower but you start with Lapua brass which is a big plus. It’s not immune to clickers as some have seen but it gets you in a similar performance range

I pulled my last 308Win barrel at around 5,000 rounds (last month) it was a cut rifled 416SS barrel that started by shooting 1-1.1” at 400y and 2” at 600 when it was mostly 2” at 400 and 4-5” at 600 I decided to change it out barrel inside finish was rough enough that I had to clean a lot more...

for those of you that have worn out a 308 Winchester barrel in a bolt action rifle, how many rounds did you get before changing the barrel? to semi-standardize, let’s say that ”worn out” means your group size (from peak accuracy) has increased by 50-100% meaning a 1/4MOA barrel is now a 1/2MOA...

we are fitting barrels to actions and tuning extractors/mags etc for each rifle now. there were a few issues here and there when this was being offered as a pre-fit, but theres very little issues with the fitted/tuned versions that were doing now you can reduce your cost by utilizing a bolt...

Look for a pip on your ejector remove the ejector and see of you still get marks on your case heads, both before and/or after firing remove the fire control and see if the bolt closes on virgin brass with ease (gravity) the marks in your chamber can be sanded out, almost looks like it was...

Pretty please, with sugar on top, dont do this to one of my chambered barrels

I have noticed this annoyimg feature in the unit I’m using, reset time is prob 3-4 seconds but for an impatient guy like me it’s frustrating. When you’re in azimuth, inclination, etc it takes even longer to reset

Agreed, looks like the 1550nm lasers are the way. Just trying to understand if I can get the 905nm ones to work or if I have to pony up the 3-4x premium for the 1550
