Abilene Slim SASS 81783 Posted May 1, 2018 Share Posted May 1, 2018 In another thread I mentioned researching the idea of long range shooting. In talking with a pard this past weekend, he mentioned that not all rifling is the same, and some rifles aren't compatible with BP rounds. Since I'm thinking of shooting smokeless and BP, are there certain rifles I should avoid? Link to comment Share on other sites More sharing options...

Garrison Joe, SASS #60708 Posted May 1, 2018 Share Posted May 1, 2018 Yep, the microgroove barrel versions of Marlin rifles sometimes need a hard and full-bore-size bullet to keep from stripping the surface of the bullet. But, you can usually find a load that will give good if not excellent accuracy. The Ballard (standard size grooves and lands) style barrel in the Marlins are quite strongly sought after.

John Boy Posted May 1, 2018 Share Posted May 1, 2018 Major - pick one, their all accurate ...http://www.trapdoorcollector.com/shooterstext.html My favorite though is a duplex load 10% less with 4895 and the difference FFg black powder = total charge if BP Link to comment Share on other sites More sharing options...
Mad Dog Jack, SASS #77862 Posted May 1, 2018 Share Posted May 1, 2018 I was told many years ago (1980ish) to avoid shallow grooved rifles with BP and soft lead. The one time I had issues was with a microgrooved Marlin, tried hard lead and the groups tightened up some but I traded that gun off anyway. I also was told sometime later that worn out big bore rifles don't shoot so well with BP because they can't grip the bullet as well. I have no experience with that though Link to comment Share on other sites More sharing options...
The Original Lumpy Gritz Posted May 1, 2018 Share Posted May 1, 2018 What do you call LR shooting? True LR starts at 500+ yds. Look for Ballard type, and avoid Marlin type micro-groove for BP use. In .45 cal rifle, you want a 1/16-1/18 ROT for the bullet needed to achieve this. The biggest deal in BP use for LR accuracy, is your fouling control... I have a proven .45-70, 1K yd load for a single shot rifle. Just because it works in my rifle, does not mean it will work in yours. OLG Link to comment Share on other sites More sharing options...
Abilene Slim SASS 81783 Posted May 2, 2018 Author Share Posted May 2, 2018 If for example, a Marlin 1895 .45-70 has micro groove or Ballard rifling, will that be stamped on the barrel? Link to comment Share on other sites More sharing options...
Garrison Joe, SASS #60708 Posted May 2, 2018 Share Posted May 2, 2018 Look down the bore. Microgroove will almost disappear; Ballard will be very visible even dirty. Sometimes a barrel is marked Microgroove, but not always. Good luck, GJ Link to comment Share on other sites More sharing options...
