Re: HS Precision stock and factory bottom metal fit Thanks Chad. I don't have the magazine box installed yet. So, I think the problem is that the bottom portion of the stock doesn't have enough material (most likely) or that the bottom of the aluminum portion (where the pillars would...

I bought a 700 stainless ADL during one of Dick's sales last year. I just bought an HS Precision Pro-Series Sporter Stock and some factory bottom metal. After I assemble everything, I end up with a small, evenly spaced gap the whole way around between the floor plate and the stock. I do not...

Re: Trying to understand BC calculation formulas Thanks. It appears, according to this, that Sierra's method is to computationally iterate between narrowing BCs until a particular BC produces the measured final velocity, given a start velocity and various environmental factors. (Source...

I know software exists for calculating BCs, but I'm trying to understand the math behind it. According to wikipedia (which we all know is the ultimate source for correct information, ha ha), The variable information is here...

Re: What size Torx for GAP action screws? So, does the GAP/Badger DBM use Torx Plus IP30 screws (instead of the Torx T30 size)? If so, would the Torx T30 fit, albeit not to the maximum torque?

Re: What size Torx for GAP action screws? Thanks Cigarcop!

I need to get a Torx wrench for my GAP Crusader. Anyone know what Torx size they use for the two action screws? I'm guessing T30 but I can't verify this. Thanks!

Re: Adding 1" to stock length of pull Interesting. Good idea. The recoil pads on the B&C and McMillan stock all appear to be glued to the stock -- I can't find any screw holes to remove them, unfortunately. Is a band saw the proper way to cut the recoil pad off of the stock?

I've come to realize that I need an extra inch of length on my guns due to the fact that I have a long neck. I have a bunch of B&C Medalists on my Savages and a McMillan A5 on my GAP. I basically need to make each of them 1" longer. I'll probably send the McMillan stock back to GAP but I'd...

OK, I have a new GAP Crusader in 260 and a Savage that I customized, also in 260. Both are consistent 10-shot, 1/2 MOA guns at 200 - 300 yards with my two 260 loads -- one with 123gr AMAXes and one with 140gr AMAXes. What's interesting is that the GAP shoots both loads into basically the same...

I bought a GAP Crusader 260 last month. Great gun and I'm happy with the performance I'm using my handloads. However, I wanted to try some factory match-grade ammo to see how it compares to my handloads. I bought two boxes of Corbon 260 ammo -- one with the 123gr Scenar and the other with the...

Re: Recognize this powder from a 260 load? OK, thanks guys. Looks like Quickload likes that powder too. Seems to give pretty good velocities (on "paper") compared to the H4350 I've been using.

This powder is used in a 260 load with a 123gr match bullet. Anyone recognize what it is? Just curious. I already have a load that works great with my 260. (Click on the picture for a zoomed in version -- but be warned it's 3MB.) Uploaded with ImageShack.us

Re: Unthreaded tenon too long on muzzle? Chad, I agree with everything that you wrote. This barrel is chambered for a 300 AAC Blackout, so it definitely is a .30 bore and yes, the wall thickness is pretty thin. In retrospect, I should have gotten it threaded 5/8x24. Regardless, the...

Re: Unthreaded tenon too long on muzzle? Wow, great responses all around. When I got home this evening, I remeasured the unthreaded portion and my measurements are correct. I also tried screwing on my AAC Ranger and sure enough, it does not bottom out on the barrel shoulder. I also checked...

I just received a barrel that I requested be muzzle threaded 1/2x28 for a suppressor. Here's a pic: The entire "stub" measures 0.630". The unthreaded portion of the tenon is 0.130" (which leaves 0.5" for the threaded stub). The 0.130" unthreaded portion seems long. Worse, there's no...
