Custom Rifle Woes-What Now?

Light varmint benchrest is 10.5 lbs and at that weight they shoot aggs in the 0.1xxs.

7mm-08 is a problem cartridge? Wow first time I have ever heard that.

Comparing OP's rifle to a LV rig is insane, they are apples to oranges, completely different.
Pedestal rest vs likely Harris bipod?
6ppc vs 7-08? How many benchrest shooters use a 7-08? Near enough no-one, I'd bet.
Wind flags? Doubt it.
Barrel tuner? Nope.
OCD neck turned, volume sorted, primer pocket uniformed brass shooting super high end weight and bearing surface sorted benchrest grade bullets?
etc
etc

And he never said there was anything wrong with the 7-08 as a cartridge, he simply has a different level of what he considers acceptable performance.
 
Any updates on this. Kudos to the builder for the service.

I received the rifle back a while ago. It had been rebarreled with a Proof warranty barrel.It did shoot considerably better than the original barrel.

Shane had asked how it was shooting. I replied that it wasn’t great. Shane recommended that I bring it back again. I delivered the rifle back. Shane turned the rifle over to a friend for testing/load development. The friend did some useless load development and played with it at the range with his buddies. The accuracy of the rifle never got verified and the load data was what I already knew.

I got a very experienced friend to do loading for it. Basically he got the same results as I did maybe a little better. The rifle will shoot maybe 3 rounds touching then starts to walk all over the page. Essentially the same problem as before just not as bad. I absolutely could not get any consistency out of that rifle. It in all honesty was a 1 moa rifle. Most factory rifles are more consistent.

Shane got frustrated in the end and condescending. I wasted too much money trying to get that rifle to shoot. I eventually replaced it with a Benchmark 1/9 twist pencil barrel on a bighorn action. I got the replacement rifle to produce a .5moa 5 round group on my first round of load development. I traded the proof rifle away.

Long story short it didn’t end well. I have no idea why it shot so poorly. Neither did Shane apparently. I guess its way better to simply do a prefit rifle than deal with an oilfield salesmen. I don’t know if its a Proof Research issue, poor gunsmithing or something else. Either way I wouldn’t deal with EM Precision or try another Proof barrel.
 
Steel heats at different rate than carbon fibre then you get harmonic flexing with more shots fired!

How did it shoot? What was the group size/distribution like? You said the first barrel was a 2MOA gun, how much did the second barrel improve?
 
It was a 1 moa gun. I could get maybe 3 rounds to touch then next shots were an inch away.

I've seen another CF barrel do this, it was a Christensen Arms. Every group was 3 rounds touching, then 2 rounds touching an inch away. Different shooters, different ammo, same results. Buddy sent it back, Christensen said something about the barrel unwrapping.

If there was something wrong mechanically or with the chambering, I would think the groups would shotgun pattern, not show a consistent trend.

Your probably right. I dunno I’d say experiment failed I don’t recommend CFW.

Sorry if I offended you. It was only a rifle weight comparison Sir. Sporting rifles can be bagged and shot in a similar fashion to get the most accuracy and help eliminate variables. Just check out sinclair for example and their sporter adapter for bench shooting.
 
what have you found? Do they happen to have specifications so we can compare apples to apples or what are you thinking.

As far as CFW's go. If I was asked.......I could only recommend Hardy or maybe HCA right now. Both I found load development easier and quicker than a Proof.
I sent a lot of rounds down range to finally reach acceptable results with a Proof.

No offense taken, I was just pointing out that you can't compare the performance of two rifles based solely on weight. Unless the OP was actually shooting in the same fashion as a BR rifle, it still doesn't work.

And most crucially, I've never seen or heard of a CF barrel being used in benchrest.
 
I was always sceptical of carbon fibre wrapped barrels being a materials technology engineer, just could not make sense of them. Even so I had a rifle built with a Hardy carbon barrel. Now after about 1.5 years of trying... with two rifle smiths involved, one can say the rifle improved from initially 2" to 1" best 3/4". Never had a rifle as inaccurate as this one. Even cheapest factory rifles I zeroed for friends were better. The carbon barrel does not come close to the T3 factory rifles with factory ammo I also have.... why bother? I do hunt with the Hardy barrelled rifle however she will be replaced.
Just bought an old T3 action which will get a stainless steel barrel again. At the moment I am thinking old school Lothar Walther, maybe even get them to chamber and lapp the barrel.

I've repeatedly shot 1/2" almost touching groups with Husqvarna 1900 actioned 23.5" barrels, consistently....and not too ammo finicky either....I figure those Swedes had barrels well sorted out in the late '60's....
New -- is often -- not better...imho...
