PM me your address and I’ll send you a spare Gunworks recoil lug I have.

One of the dudes from Capstone Group mentioned that the packaging was to address case neck damage that was occurring with the plastic boxes. Unfortunately now it’s only 100 pieces per box, so no...

A GT will easily do 3,000fps with a 105gr class projectile, loaded at normal length. But at 2.4” COAL, the boat tail will be well below at case neck shoulder junction, so a 95gr might be easier to...

Hit up Geoff from the GunRack to see when he’s getting an order in from Armageddon next. Might save yourself a few dollars.

I regularly run a SpeedTracker chrono when shooting groups and testing ammo and the SD / ES of TAC22 is consistently 10/30, which is exactly what I get with RWS Special Match also. This is across 2...

What’s the projectile you’re intending to run? I think the reamer specs allow a 156gr Berger to be seated with a 2.97” COAL to touch the lands. They also like being jumped….

NIMROD from memory, Dreamer on here had a Kimber Montana that he rebarreled to 6mmCreed. I think it was a 243 previously.

Ben, find brass that meets the criteria below

1 - Factory round, pull the projectile and dump powder, confirm it fits in your chamber
2- case fired in your chamber, sized and fits back in your...

Did you go with the universal tip or the custom fitted tip? Am curious what additional performance the custom tips provide.

Not that you can accurately measure case neck ID with calipers, but Something is definitely not right then. With a 0.224 projectile and 0.002-0.003 interference fit in the case neck, the neck ID...

I doubt it. When seating the primer into the pocket, it requires a small amount of crush as the edges of the cup bottoms out on the base of the pocket and pushes the anvil up into the primer paste to...

I think this is the most significant aspect of breaking-in a barrel, in that it’s actually the chamber / bore transition that needs the attention. I’ll use abrasives on a patch and short-stroke this...

I’d say it’s a function of weak firing pin spring and the thicker cups of the BR-4’s. Replace the firing pin and spring assembly.

Shehane isn’t AI ‘improved’. Just has less body taper compared to standard 284W and increases powder capacity by about 3grains or so. 7-6.5PRC has similar capacity, but just does the same job easier.

7-6.5PRC is becoming very popular in F-Class circles….2950fps with 180 Hybrids comfortably with 30” barrel and without needing to push it hard. Achieves 284 Shehane performance without trashing brass.

From a reloaders perspective, I think the 6.5PRC has been let down / hamstrung by a lack of collective input and agreement from factory rifle manufacturers, brass manufactures and sizing die...

I’d be inclined to sacrifice another case by running it through the AMP and confirming the correct Aztec code and that the cases are being annealed adequately.

It would take excessive headspace...

Yup, agree with all the above sentiments. Colin and crew are a good bunch! Can’t go wrong by giving them your business.

You generally get 0.5 thousandths of spring back when firing. So your chamber will be 0.2975 - 0.298 at the most.

Just because you don’t understand something, doesn’t mean I’m wrong ;-)

Keep an open mind Micky and listen to what’s being shared. You might just learn something.

I'm saying you can't achieve that level of consistency without understanding the variables (and their effect) and then ensuring you manage that variable in order to control the effect of it. In the...

Its not shooting yourself in the other foot at all. Its being aware of the factors which affect harmonics and ballistics and then managing their effects for nett benefit.

And I don't focus on...

It’s not a moot point. The tip to ogive variance is exactly what you need to be aware of when seating projectiles, as any variance in ogive shape will absolutely give different case base to ogive...

You’re right, my maths sucks. But the point remains, +/- 1mm difference in seating depth makes a massive difference.

It’s quite common for rifles to have a CBTO tune window (node) of 0.006” (1.5mm). So using your example above, the 1mm variance either way equates to 0.008” between shortest and longest CBTO for a...
