22x47 Lapua reloading advice needed.

[VinceMule]

I was speaking of a used barrel blank that I purchased from a gunsmith. The barrel was abused, not cleaned frequently.

Here is a pretty good video, stupid simple educating process



1, 2, 3 and 5 micron Al Oxide is used in various pastes and solutions, 5 being the most aggressive.

I don't have time to play with used barrels. I order in a blank, reamer, stock and action. Drop it off with my Smith and pick it up in a week or two. Then I know with a new barrel where I start and where I end. I don't have barrels set back either. When the time comes. I have a new barrel spun up.

Competition is serious business

I like to play and be creative Seeing what I can get out of a barrel, IF I do my barrel analysis correctly. I do avoid fluted barrels, seen too many of them not shoot as well as I expect.

First, you need to invest in a Teslong bore scope, they are very inexpensive. With the amount of powder you are using in a small bore, with the speed, you are getting some serious fouling. Cleaning every 40-60 rounds is way over the limit.

You will become your own expert with your cleaning methods, and I can tell you right now that your bore was not clean when you thought it was clean...this is the start of your problem.

Next problem, the barrel may not like the bullet, but you do not know until you get the bore scope. I paid $89 for mine that plugs into an old lap top. The best one is the hand held with the 5" screen..

I have been down this road of helping shooters with fouled barrels many times. When they got the Teslong, bore scope, they were simply amazed at how ignorant they had been. I have two 22-243 AI's, and I shoot the 60g Sierra's at 4000.

I would go on the hunt for some Berger 77g OTM Tactical, AFTER you get the Teslong..

AA2700 is close to the burning range of H4350. 2700 will give you another 30% minimum barrel life, compared to the H4350 with Reloader 17 eating your barrel up like you are shooting battery acid.

Does it really help when you have a barrel that doesn't shoot tho?? Sounds like a lot of work. If the barrel doesn't shoot right off and contini to shoot for 300 rounds or so then just some normal cleaning with patches to keep carbon build up at bay… it's a garbage barrel imo or a poor chamber job. I only have developed loads for about 30 barrels in 22, 6mm, 6.5, and 7 mm and have yet to find a barrel yhat does not shoot consistently well for a good life for cartridge and I clean very minimal. I have tried breaking them in and just shooting the hell out of them … all the same. They shoot with a good bullet and moderate/optinal load. Some bullets tune easier than others for sure. So I used the easy button bullets. Hornady atip or match, Nosler RDF, Berger elite, EOL, LRHT … use them jump them 30-50 thou and don't waste time and money with inaccurate rifle systems. Bullets I will never mess with again… VLD, ELX, accubond. Yes they will shoot, sometimes … the others shoot nearly every time lot to lot barrel to barrel. I like easy buttons.

I agree with VinceMule and get a borescope. Had same issue with 30-06 at around 200 rds and I had a huge carbon ring. Just my experience.

Barrels can be amazingly tolerant of what some might consider abuse, while others consider it normal use. If I get a custom barrel of any caliber it's such a novelty to me that I tend to baby them a lot. I just can't afford the number I'd like so what I have I take very good care of.

The scope is a very useful tool to know not only how clean your barrel is but if or how quickly it's wearing. And dealing with wildcats... well the wild isn't in there because it sounds cool! Wildcats tend to wear a barrel, especially the leade, much faster than most other cartridges. Keeping a close eye on this, which usually starts out as "checking" can help if you want to a long life from your barrel. Or at least know when it's on it's last legs, even if it still shoots ok. I've seen barrels start to deteriorate slowly while shooter blames himself for the occasional flyer or not great group, when it's actually the barrel circling the drain! Ok, granted, it's usually the opposite but not always. The scope, once you learn to use it properly and learn what it is you're actually seeing, is a tremendous tool and nothing else can take it's place. I highly recommend them for anyone into real shooting precision.
Cheers,

Lots of good info here.

Just checking. Did you check neck clearance? You did mention turning necks. Just making sure that you turned them enough since necking down from 6mm to 22cal could lead to an issue.

I'm going to be honest with you. I have a couple 22x47s . With the components you have and rifle you are shooting the first group isn't acceptable really. You need to try a different bullet probably. The Berger 80.5 fullbore is a very forgiving bullet. Kills coyotes and varmints very well. If your gun won't shoot them it's the barrel. Clean it really well and start at a safe charge of 4350 and work up. Let the barrel cool good don't just hammer down on it. If it doesn't shoot then you have problems.

 

[Roperboy87]

If I was to pass any advice along on this gun of your I would say that you have to be up above max on pressure with the h4350 powder I would try at least a grain less than what you are using. That's where I would start. This is a 3 shot 300 yard group with mind. I'm at 38.4 grain of powder h4350 and 85.5 hybrid

 

[KzDurango]

This is an old post !!
I since then switched to Berger 80.5 fullbores and it shoots 1 hole groups. See attached photo

 

[skipglo]

Start with the obvious....tighten all screws, bases,rings,action...can save alot of frustration...even your better group shows climbing/walking... something is loose.

 

[americanquigley]

Have built a few, I'd try a different bullet. See what it likes. Try few ladders see where it wants to shoot with different bullets.

 

[Blackwater Red]

First off.

Is the barrel free floated, not contacting the stock anywhere?

Is the action bedded?

I shoot a 22x47 with a 26", 1-8 Brux. 88gr ELD-M's @ 3231 fps on top of 38.3gr H-4350, BR-4, Necked down 6.5x47 Lapua brass.This combo is spooky accurate. The 77gr Sierra Matck kings shot really well over RL-26 @ 3600 fps.45.5gr RL-26, CCI 450.

I could never get the 75's to shoot well.

100 and 300 yard groups.

Please check your math on the 100 yard target. You used .264 for the bullet size instead of .224. Still impressively precise!!!
