    Found a kit, new in box today. Jumped on it like a doggie and his bone.

    Check the barrel & see if it is a Douglass. If it says made in Spain it most likely is not. There great guns. I have a .50 that I bought the kit in 1979
    & still have it. Great rifles.

    Hi, I`m new here, Nice find VRH. I managed to pick up a CVA Mountain rifle a while back in 58 calibre from a guy who had lived in Africa and hunted with it he had also taken it to the States competition shooting.
    Have a question and hope someone can offer a solution. It shoots beautifully with 120gr Goex 2F, 570 prb, and ticking. One ragged hole stuff at 50mts. My issue is and I hope Fly will chime in, is it throws 6-8 inch groups with home made Black powder at the same distance. I have been making my own Powder for a few years now as Commercial powder is hard to find and we have shipping restrictions on it. My homemade shoots well in my other flintlock and cap lock rifles but not this one, they are 50cal, any suggestions??

    One other thing while I think of it , is Potassium Nitrate restricted in the U.S? I see guys buy stump remover and the like to make their powder. Here I just go to the Farm supplies store and get 25kg of Potassium Nitrate for about $45us and a 2kg pack of sulphur for about $10us. That's pretty cheap when you consider Goex 2F sells here when you can find it for $50us a pound tin. It works out I can make 28kg of powder for the same price as a pound of Goex ,I try not to use too much of the Goex!!

    those made in spain CVA barrels were(are still) top notch shooters - douglass might make a difference to resale price but I dont believe it made a difference on the target

    Are you weighing your 120 grains of homemade? I cant get the density into mine - my measures are about 20% lighter weight of powder so i cut bigger measures to save re adjusting sight settings - strange though ! I have shot CVA's for 30 years and usually they shoot any powder charge pretty well - not usually load sensitive to that extent.

    Up till now have been doubling the thrown measure IE: flask spout measured for 40gr 2F Goex so have been using 2x a spout full to give equivalent power range, same impact area on target. That means 6x spouts to get the 120gr. If it was a bit inconsistent on the up and down I would just assume powder fluctuations but the CVA is also tossing the balls left and right. Got me perplexed anyway, especially when the 50 Cal's shoot it fine and so does my Zoil Zauve another 58 cal.
    Powder is corned by sifting to size and not compressed. Have had arrive today a mini set of electronic scales, figured weighing powder was the next step so will see if that improves things.

    Yeah I am puzzled by this the CVA barrels I have shot have all beeen very unfussy about powder quantity - my 50's I used to shoot 40 grains for 25 yards and just add more as the range increased - saved on sight adjustment - My 54 I started with 120 grains of FF - the ticking patch wouldnt take that all the time so I used a little backer patch on the powder first. You need good ball in these bigger calibres - so weigh and measure ten balls to see how that works . patch size ? if its too small is a headache loading - but yu getting a group with goex ................................ do all your basic stuff - weigh the charge - weigh and measure some balls - pick up patches and make sure shes not holin em - take the rear wedge out of the wood and put a piece of cardboard (manilla folder) between barrel and wood just in front of the forward wedge so it goes in TIGHT - just pack the width of the bottom flat is enough .........I would try all these one at the time - they all things that have made a difference for me at various times when I was getting serious .
    keep us posted eh.

    Cool! I see despite the volumes of recent posts, folks think Douglas made the barrels. Yours, without seeing the barrel markings, was made prior to 1979 because of the patch box used. The barrel likely says "Made In The USA". Whether it has this marking or not, they are all exceptional shooters! Enjoy the build and making smoke when you're done!

    Good shooters. I have .45, '50, .54, and .58 Mountain Rifles. Its amazing how many of these kits are still around NIB. I bought a couple several years ago and still have a .32 on the bench under construction. Need to get back on it.

    What's the likelihood that your powder simply does not have the initial push to adequately obdurate the boolit while Goex does? It's the only difference I can think of. What is your boolit - pure or alloy?

    Hi Wayne,
    That thought had occurred to me though I did put one shot through a Conograph that a guy had at the range a while back out of curiosity and with the equivalent of 120gr in homemade powder it gave a reading of 1570 something FPS so I was pleased with that. The .570 balls I cast are from pure lead from roofing sheet. I have also experimented with .562 balls made from wheel weights with much the same effect as far as spread goes. Now that I think of it also had the same when I shot the .562 balls cast from pure lead which had me change to .570 balls in the first place. The .570 mould came from the guy who sold me the rifle, it was the one he used it just took him a while to find it. Only good thing to come out of this so far is my wife is quite happy , she knows I won`t get another gun till I get the one I`m working on shooting right
