I've been noticing the bases of my boolits (after seating a gas check) are not as good as they used to be. Something has changed in my mold or technique and I think it's one of the reason I'm having fits with grouping. I'll get a 3/4" group at fifty yards then shoot the same load and get three boolits touching and two fliers a couple inches off.
I'm a pan luber mainly because I'm too darn cheap to do it any other way but that's gonna have to change. Using my lee push through (.311) sizer sometimes I get a perfect pressure ring on the base of the check, sometimes I don't. Obviously it's my fault but I think the gas check shank being too tight is the culprit. Because I'm sizing down very little I'm thinking there's not enough pressure to sets the check squarely. An out of square base turns a rifle into a shotgun.
On my boolits with a meplat I use a pair channel lock pliers I ground smooth (jaws) to seat the check firmly but with a spitzer I really need to be using a nose punch and a press. That's why I think I'm gonna HAVE to break down and buy a lubesizer. That, and I'm shooting in such volume now that pan lubing is becoming a pain.
Any thoughts, am I on the right track?
