That's the charge that performed the best in the previous development. First 3 shot group was .3" and the second .7". It is also coincidentally the max charge in the Sierra manual but that's for a coal of 2.26 of course.

This is also only the third rifle I've loaded for. The 243 and 6CM were effortless. This is my first attempt at troubleshooting.

Got shot gun size groups today with the rounds closer to the lands. Getting a hold of a torque wrench and some leather and reinstalling the barrel to spec. Something is way off.

Could be, I guess if it is I'll learn the hard way. I've done it this way up til now with great success: http://www.texasprc.club/preidloaddev

Luckily the 224 valk barrel is supposed to last a long time 🤣

I do similar "ladder tests" ....but 5 shots each load, and use a Magnetospeed Riflekuhl to more quckly reduce barrel temp. I find I can often shoot a good 3-shot group with a decent load. But only a great load can be shot 5 times and get a good group.

Once I find my node, I come back a differnet day to try to repeat it. That might be problematic, if atmospherics are significantly different, but then again.... I can't really wait till everything is perfect to shoot.

Yeah, maybe I have had beginner's luck til now. One range trip and 35 rounds with my first precision gun in 243 to find a great load and two trips and maybe 60 rounds in my RPR in 6CM. And the rpr would have been one trip if I wasn't having some serious magazine issues.

I found a great load in 338 Norma in under 50 rounds. 6.5 CM took prolly 200 rounds (found a low velocity node quickly. High velocity node took longer) My AR15? I sold it after some 500 rounds being unable to find a good load. (That may have to do with me wanting bolt gun precision out of a gas gun.... or other personal inadequacies)

Yep, that's why I decided to start with bolt actions and then move to semi auto after I got some reloading experience with them first. People really struggle with the AR platform, especially in say a non 223 cartridge like the Valkyrie. Quality barrels also help, but in my Valkyrie case it looks like the criterion prefit is not able to compensate for my or other inadequacies.

People struggle with AR's because their fundamentals suck. Period.

I couldnt consistently keep my AR under half an inch at 100 yds. Anywhere from 0.45 - 0.75"... not sure if thats fundamentals sucking, as I use the same exaggerated fundamentals for both.

Dont know what more I could do for gas guns. Best guess? My follow thru is good, but my shouldering the gun is prolly off.

Generally speaking, it's the indian, not the arrow. Most AR's are fairly accurate (like near bolt gun accuracy, and in some cases, better). Poor trigger control and follow through are killers with a semi-auto. Any deficiencies in these two things and a semi-auto will amplify it.

Go look at the accuracy some of the guys shooting NRA high power get out of their AR's.

Better yet, go pull butts for a Marine Divisional or Intramural match during a rapid fire stage. You'd be surprised at how small some of the groups are at 200 or 300 yds...with iron sights.

With semi-autos fundamentals matter a whole lot more than with a bolt. A bolt gun let's you get sloppy if you're not careful.

I don't hang around with a lot of what would be considered professional shooters, e.g. military sharpshooters and the like.

As such I've rarely / never seen a civilian match bolt gun accuracy with a gas gun.

And I've heard very knowledgeable people say there is an inherent inaccuracy to the Gas gun as its semi auto function begins while the bullet is still in the barrel.

Yes I know people argue that, but logically a Gas gun has to begin its cycle with the bullet still in the barrel because once the bullet leaves the barrel, the whole system depressurizes and cannot function. And if the gun begins to cycle with the bullet still in the barrel it is producing movement that no shooter no matter how professional can eliminate every single time.



But yes.. .generally, it's the Indian not the arrow. A quality semi auto can out perform what 99% of shooters are able to do

Well, now I have a different problem lol. Not sure how I managed to do this a couple times before with the Savage as everything went smoothly. Tightened the barrel vice enough to where the barrel doesn't spin but now the action just spins with the nut. Torque wrench doesn't work because I can't find an extension long enough so that the torque wrench will clear the barrel. I seriously doubt there is 35 ft lbs of torque on the nut before the action starts to spin with it. Just sitting in a chair I can use a couple fingers to lift on a box end wrench and the action spins. I don't remember having this happen before.

Edit: I put the action in a regular vise and wrapped it in leather and gave it a tug. Torque value unknown still. The crow extension flare wrench suggested by big Horn does not clear the barrel with two different torque wrenches I used, just in case anyone was wondering.

Huh??

You should have 2 wrenches....action wrench and barrel.nut wrench...you turn the action till it contacts the go gauge. Now pull the barrel nut wrench and action wrench in opposite directions till you have 35 ft lbs on the nut....make sure the nut is hand tight against the action before attempting to tighten and I hold the action solid and torque the nut so I'm not changing headspace

There shouldnt be any way for the nut to spin if your doing this properly

LOL. forgot about the action wrench. I have to dig up that action wrench. So last time I did it on my Savage the set up was different. I didn't have my viper barrel vise. I put the barrel in a vise with some soft jaws and then used a wrench on the nut and the action wrench behind it and tightened like you said. I guess I'm losing it. We'll, this suggests to me torque may have been the problem after all. Now to find the action wrench.

Not trying to be a dick here, but should you really be setting headspace on a barrel? Based off your comments, I'm a little concerned you may be over your head here....

Fair question, I grew up playing video games lol. But I've done it several times before. My first attempt on a Savage 243 ended up great first try. Safe and sub 1/2 MOA out to 850 yards. I'm using go/ no go gauges of course.

In that vein though is it ok to pad the action in a regular bench vise to keep it from moving and then tighten the barrel nut or do you have to have the action wrench? Can't immediately remember where it is.

Assuming you're barrel is in a vise, and it does not spin, you don't really need the action wrench for installing a barrel.

There are many ways to skin this cat. It varies based on what is being held in a static position; the action or the barrel. This is where I think you are getting confused.

That makes sense. I remember when I bought the wrench from Northland shooter supply they said it had a notch for the recoil lug. They said that without the wrench I could twist the action. But then I read online that people were putting metal bars through older weaker actions to use as counterforce and that's how they were ruining them.

I just posted a 224V savage small shank with my long freebore reamer in the FS section if your looking for one fast
I'd like to go with a shouldered prefit, but if you had said you would like to trade a origin 6.8 bolt head for a .308 bolt head that may be a different story.... although I dont really see a down side in having both. Thanks though!
