I think you might have your twist rates twisted. The faster the twist, the better for heavier bullets(1in18). The slower the twist(1in48 or 1in60), the better for lighter projectiles like round balls. You want a faster twist for heavy conicals, not slower. Tom.

With the correct fitting conical and weight, that GMB 1:28 should shoot conicals excellent.. slug your barrel and order some bullshop .460 gr and some UC 445 gr conicals.. 70- 80 gr powder.Ray

What instrument should I buy to slug a barrel. I have a "slide rule" type measuring device, but it only goes out to 1/32 of an inch.
Also, what kind of turnaround time could I expect on an order of bullshop this time of year?

Sidelocks are a pain to slug, since you can't push it out from the breech end. are the No Excuse bullets falling down the barrel or can you feel them engraving on the way down? My Knight wolverine(GMB barrel)shots the .503 great and barely engraves them going down. enough so that it doesn't come off the load. borrow a micrometer or borrow one and measure the No excuse bullets and use that as a gage for what will fit.Ray

The no excusess definately engage the rifling. Can start with a thumb though, and push pretty easy with a ramrod. Don't fall down the barrel though. In general is the tighter fit better?
And I also want to try the Hornady FPBs more. Only had a handful, so they didn't get a real test. Just really wanted to see if they would go down well and shoot. They did.
