Well hardly an intensive test. I got my barrel (209x50 Encore) back from getting two more holes tapped for a 6 hole base, mounted a Konus 1-4x25 30 MM scope on it and put the barrel on the action. I had ordered and received 4 pounds of the MPB from Grafs. I got it sighted in pretty fast but I noticed the scope sits too far back set as far forward as I can get it. A combination of the adjustment knobs being in the wrong place and the eyepiece being pretty long it hit me in the face 4 times. Not hard enough to make me bleed but a bump none the less. So I flinched a few shots. At any rate because of this I kept my charges down to two loads of 80 and 90 grains for testing. The powder puts out plenty of smoke if that is important to you. Fouling is minimal. I normally swab by running a wetted patch (this time with orange windshield washer fluid) turning it over and running it again then running a dry patch between shots. The first patch is dirty but the second is pretty clean. Accuracy and repeatability was very good when I wasn't flinching, I wasted three shots and I only fired 15. Cleanup was a breeze I ran both sides of a wet patch and a dry patch 3 times and the barrel looks spotless. The breech plug remained clear and I did check it at shot 11 and when I was finished. So now I have to find a scope that I can get the eyepiece far enough forward so it doesn't knock my shooting glasses off. I was shooting green ribbed Harvester sabots and 240 gr. Speer Unicor .429 bullets which loaded just right.
 
Did you notice this part about the EABCO rail?

Original EABCO KeyLock Magnum precision machined scope mounting base for the TC Encore and Pro Hunter. Mount it with the overhang to the rear to shorten the eye relief (Handgunners often mount it this way). Or, mount it with the overhang forward to get maximum eye relief (Rifle shooters prefer this). Mounts to the standard T/C 4-Hole pattern or can be mounted with 6 screws for maximum hold with the hardest kicking cartridges (requires 2 more holes drilled and tapped).
 
I wonder if the hole spacing is the same as what I have now to match the Eabco base?
No idea. Shoot them an email. All i can tell you is they are true picatinny. Or at least mine is. So ring placement is far more versatile.
 
Or get a long rail from EGW and have the holes drilled to match your rifle.
A dozen of this 12 of that, just throwing things out there.
EGW was the only Pic rail (non-peep) I could find for a CVA, and I seen they have long blank rails.
 
GM54, thanks for the heads up on Hanks rail, couldn't find Contessa's tho.

RickT I would get that scope forward before you set yourself up to flinch, it is sub-conscious, and hard to break yourself from it.

Sure did and have the overhang forward. The scope has the adjustment knobs too far forward. Actually the scope is made to be used on AR15 style rifles and it is a nice piece of glass. I am going with an older Leupold 4 power. I like the SSK rail but going to the Leupold will solve the problem and knock some ounces off.
 
Further testing reveals that 85 grains of Multi Purpose Black weighed is an excellent load. Also my Winchester 209 primers seal the breech plug pretty well as very little blow by if any is getting past the primer. The Leupold is an older model that doesn't have "clicks" and took a few more shots to get sighted in. So I didn't quite finish that chore as company came over, turned 65 Saturday.
 
Back at it. So I decided to finish my sight in now that it is only going to get to 90 degrees today and use the bullet I have chosen. I also thought that I could use a powder flask I have with a 100 grain by volume measure on it to make things go faster. The flask didn't work out as the APP doesn't flow thru it smoothly causing some variation in my load. My fault for not noticing it soon enough and it caused me to go through a very unfruitful re sight in. I changed bullets to the 270 grain Deep Curl Speer and decided to drop my charge to 80 grains by volume after deciding that 100 grains by volume was more than I needed. I used the flask to fill an adjustable measure and things began to act normally. Still 34 shots to get me 2 inches high was a chore for an old guy but I should have made sure the flask was flowing powder correctly in the first place. There are pluses and minuses to the soft recoil pads on the Flex Tech stock, yes the soft is good but it also lets the rifle move further back when it goes off so you have to hold the forearm firmly. I finished with a 3 shot group of 1 1/2 inches in just the right place. A bit more on this powder. It did seem to be a hotter powder than when I shot it last. You could if you have a good loading rod load two in a row without swabbing. I dry swabbed this time between shots and every two or three I ran a patch through it wet with windshield cleaner. then a patch to dry it. Truly easy wipe downs but a crud ring does quickly form in front the powder charge position. Still 34 shots pretty easy, no missfires. That said I was soaking thru my T shirt and was damp all over by the time I was done. Wiped sweat out of my sunglasses many times. Was not my best shooter today.

Sounds like you got it figured out. Only 90 degrees? It hit 70+ today here.
I has a question, were you using your flask with the 100-grain measure to directly load your charge? Like right down the barrel? From the flask?:rolleyes:
 
Worse time to sight any rifle in when it's hot A friend of mine made me some 50 caliber cooling rods When shooting 2 rifles I use the rods to cool the one down. I made a plastic tube I put ice in and put the rods inside sweating is a problem so a towel is needed to wipe the rods down as well as swab the barrel Pin but it works

I know but the amount of shaking and other jiggling to get the tube to fill was impressive. And yes I was pouring it right down the barrel from the flask after it was wiped.
 
Ugh, do as you like, but from what I understand, there could still be embers down in the breech after the shot and swabbing, and that flask will become a bomb if'n that powder ignites. It's a rare occurrence, but it has happened. Just sayin'. You probably already know this, like I says, just sayin'
