Gunsmithing 223 AI Prairie Dog Rebarrel - 4Groove 5R Rifling

I have been hitting dog towns for the last 6 years with buddies. Running 223 Ackley. Initially I was running a Proof Competition Contour that I had a local smith open up to Ackely Improved. IT would shoot bugholes with 53 VMax at 3400 and 77 SMK at 2960 - XBR8208. I screwed that barrel up with a 6mm Cleaning rod. Yes (6mm wont go far down the barrel of a 223). Bought a Bartline CF 26" 223 and had it chambered to 223 AI. Shot ok groups, but the loss of weight lost some stability. Had my smith spin up an Ospery 1.25 straight taper in 223 AI and took that the last 2 trips. IT shot 80 ELDM's pretty tight, but seemed less so with the 53 vmax (3400) and 62 eldvt's (3200).

I need new Barrel (old setup wont fit in new stock) and am looking at Remington Varmint/Sendero contour. HERE IS THE REAL QUESTION. What rifiling do I go with. 1:7 is my thought - though I could be ok with 1:7.5 or 1:8. In PRS the 5R was the answer for consistent accuracy in a 6mm. Looking at Bartline's website they indicated short light for caliber bullets 35-60 in 224, dont really like 5R rifling....... This kind of consides with my current barrel accuracy issues (perhaps percision is a better term)

Anyone got any feedback with 4 Groove vs 5R in lighter bullets on a 223 Centerfire?

Thanks for the feedback.

Did Hornady Change 147 ELD-M Bullet?

I have a Tikka CTR in 6.5 Creedmoor and my rifle really shoots the 147 grain Hornady ELD-M bullets well. I recently bought a new box of 100 bullets and I got pretty bad results with them. My rifle typically averages < 0.5 MOA for 5-shot groups with them and the new box of bullets averaged ~0.7 MOA. It was literally like shooting a different rifle.

The bullets from the new box that shoot poorly have a more translucent ballistic tip (on the right below) and are about 4/1000 of an inch shorter in the base to ogive dimension (according to my comparator) than the bullets that shot well (see below).

Has anyone else noticed this?

Feds building cross dept gun owner database

The new Palantir cross department data sharing contains all manner of concerning things, but one I don't see anyone talking about is that it will be tracking every single firearm and ammo purchase and making those records available without warrant or really any justification across federal departments.

Everyone thinks this is a good idea?

White Oak Armament knows exactly what it takes to make award winning gas guns.
The barrel nut is important. Which is why they use a massive steel barrel nut on their builds.
Bought this for a precision AR build. Assembled the upper. Never even shot it. So I’m parting it out.

22 arc build recommendations

I am wanting to build a 22 arc to throw my suppressor on and shoot prairie dogs on my ranch. Everything is flood irrigated so I will be walking around and carrying the gun everywhere. I don't want to spend crazy money because the gun will get abused. I would like a higher capacity detachable mag and the lighter the better. I've never built a gun but would like to because I'm not really interested in any bolts I can find right now. What would you guys recommend?

How long is too long for a bolt gun barrel and suppressor?

gonna rebarrel my (shot out) single shot (short action Rem 40-X) 7mm mag to 7PRC, loaded for 180s. Current barrel is 27.5", but it has a brake. New barrel will run a TBAC Magnus RR can. I ordered a Krieger w 28" finish length, but I'm beginning to wonder if that's going to be too long with a 10.5" can on it. Shortest I would go would be 26". Going to 28" will get me ~50fps more velocity. This will be a varmint slayer (Sendero profile, heavy), so won't have to carry it anywhere

When does barrel + can on a traditional bolt gun get so long as to be a mistake?
