Howdy Matt...ZUUUUBBBBAAAAA
Glad to hear from both of you . I also am running H1000 , between 96/98 grs , out of my 20 " barrel , Pistol ...so far it shoots at 3/4" . not the greatest .But , I have only 50 rounds down the tube so....
Ramshot and RL25 are next on the list to try, maybe even Retumbo . I have been shooting Hornady / SMK's but ordered some Lapua's to try .
I really don't worry about the speed , What ever gives me the best Accuracy .... I just dial it , after I find a load .
I have found it a challenge to shoot this , even with the 250's , the Gun takes some Concentration....But I'm really OLD....LOL
This is a McGowen 10 twist ,set up in a weighted (20#)Choate Sniper stock ,with the back end cut off . Has a Jewel 2oz trigger ,35 MOA Farrel extreme base and a 6.5x20 Leupold Scope .
I haven't shot it at Distance yet , but this week I'll get it out to 1000 yds .
I have a 338x375 Ruger I'm playing with also...about the same results , but with less powder .
