John you have shot in many 50 shot cast bullet events along with Jerry Hartwig.
You have NEVER shot 1240 or better.
Why not if you are such a good CBA shooter?

Accuracy from a RKS barrel when you have selected an appropriate bullet length for your barrel's twist, once you know how to properly call the wind and have learned how to properly seat your bullet to the correct depth with an adjustable breech seater  and you have determined the proper powder load to minimize your barrel vibrations. Not to mention proper bench technique. Hepburnman PM me if you would like further advice.


hi dave in my sport of BPCR Silhouette we dont do breech seating. my benchrest testing was to try and refine my reloads for my sport. i do try to use techniques the benchrest shooters use to enhance accuracy. i did chamber this barrel as the 1000 yd benchrest shooters do and designed a chamber and bullet to match. 
ive been at this sport for 20+ years and am still trying different things to improve. may never quite learn everything but thats the interesting part. things never get old!

I have also shot BPCR.
To shoot 1,000 yards you need to gyroscopically stabilize your bullet to compensate for drag over the long period of travel.
Traditionally we use a gyroscopic stability factor of 1.4 to 2.0.
Long range BPCR shooters compensate for drag by selecting a bullet length for their rifle twist that will give them a stability factor of 2.0 to 2.4.
I can calculate your gyroscopic stability factor if you provide me your barrel twist, caliber, bullet weight, velocity and bullet length if that may be helpful to you.

Long range shooting is also dependent on dynamic stability and selection of nose shape and the relative point of the bullet's center of gravity is of a concern.

Dave that is just not true over the past 23 years + I might have only shot about five 50 shot matches that I can now recall.
Show us some of your 200 yard targets your 100 yard targets are not all that all impressive to me.
I also set a new ASSRA 100 yard 5 shot 5 group average at 100 yds. with my CPA Schuetzen Jr. in 32-40 with the same 15 twist Douglas barrel back in 2013. 
Not with a Miller Action and a full blown Benchrest Rifle setup but with a Traditionally built Stevens CPA Schuetzen Junior and on a Caldwell with a sand bag front rest and enough said from me.

John I have shot numerous perfect 200 yard targets. 
My first perfect target was with a Meacham Hoch with a RKS 14:1 twist barrel and my second perfect target was with a 1885 High Wall with a 11.5:1 RKS barrel.
Here are two I shot back to back at 200 yards when I scored a 1245/1250 (247, 249, 249, 250 & 250) with wind flags 30 degrees off the flag post with a Miller DeHass with a 11.5:1 RKS barrel.

Picture of my 12th & 13th 200 yard perfect target.

So none of the five fifty shot competitions you shot in managed to score a 1240 or better and you are claiming your success is based on using poorer equipment when you had great success with it in CBA and which you claim has a better Douglas barrel.
Your rebuttal is not supporting your claim Douglas barrels are better.

My accomplishments have.

I never said they were better just that I could not get 3 RKS's to shoot.

MickB if you might be wanting a gain twist barrel Bartlien would also be another one to take into consideration. They can also provide you with whatever gain twist rate that you might like to have.

It's really not possible to choose a barrel based solely on manufacturer.

All makers put out really good barrels and all makers put out mediocre barrels. The best you do is go with the highest probability of getting a "killer" barrel based on the success others have had with a specific maker. No guarantees! 

I'm with John on the subject of RKS barrels.  I've had three .32 RKS barrels over the years and I was never able to achieve the level of consistent high performance shown in this thread.   

The absolutely best barrel I've had is a .32 cal 8-groove Shilen.  Unfortunately, Shilen stopped making those a long time ago.

Since there is a bit of show and tell in this thread.  Here is a picture of the saddest target ever shot.  The rifle was a Miller with and RKS barrel chambered in .32 RKS.

And one of his 200 yard targets Jack Hughes has shot with the Shilen barrel that he is referring too. 
I have also been out on several occasions in the past and practicing next to him. And I have watched him shoot several 200 yard 250's back to back with that Shilen barrel.

Jack the RKS barrel appears to be shooting exceptionally well - but the shooter appears to have missed a wind shift or may have screwed up his bench technique on one shot. 
Of course that always seems to happen on the tenth shot for some reason.
We call that the point of over confidence.

I am one who believes that one can end up with what I would consider to be Hummer Barrel. Jack Hughes appears to have one from Shilen. 
Myself and Jerry Hartwig I believe also have one from Douglas. 
They are hard to describe and they don't seem to bothered as much by the wind and they are extremely consistent.  
Jerry's is a 25WCF and my own a 32-40. 
They can be abit fussy to get to shoot at first but once there they just don't ever seem to change. From day to day as well as all year long.

Jerry Hartwig has made the minimum 1240 score with his Douglas hummer barrel.
We await the other hummer barrel owners to perform well and be added to our list by shooting 1240 or more.

The flyer was the eighth shot.  The shooter was me.

He was actually pointing out that he also had three RKS barrels that he could not get to shoot and the same experience that I also had.

Jack,

I have a target like that right in front of me on the wall.  I keep it as a reminder   The group is not as good, but shots 1-8 were in the 25 ring.  Then I forgot to keep my cheek off the stock and threw a 23.  It happened in Spokane at the NW regional ISSA 20 shot any sight bench match in 2017.  I still won the match though and have gone downhill ever since Smiley.  I used a High Wall with a Green Mountain barrel by the way.

Another Jack
