Just started to reload my 6.5 CM using 140 grain Speer Impact bullets. I have only loaded two rounds so far and I am fighting to get runout out of the loaded round. My previous loads using Berger VLD's were very easy to correct down to almost no runout but the two Speer Impacts I have loaded have 0.010" of runout and I cannot seem to get it much better than that. Has anyone else had any experience with these bullets?

The main one is the fit to the bullet. Take the seater stem out and try the fit of the bullet. It’s supposed to bear on the ogive of the bullet evenly, but some touch on the bullet tip first. When they touch on the tip all bets are off, they go wherever they want. Easy fix though.
Another thing is some bullets are grabbier than others and can benefit from more chamfer, so theres more glide than grab. I started using Vld chamfers years ago, and wonder sometimes what took me so long.
New on dies doesn’t mean much, some are sort of ho-hum from the get go, and some old ones are a joy to be around .
Check your brass after resizing, before loading it. I’ve had issues with the brass itself not being concentric. Always with ‘cheap’ brass. And just one brand. What causes that, is that the brass has more material on one side of the brass than the other, and when you resize, the thick side offers more resistance than the thin side, and pulls the whole thing out of concentricity.
You can also check your bullets if they are concentric or not, but it has to be done before loading them into the case. But I’ve never seen this to be the problem.

Laugh if you like, but in my 6.5 X 55 Rifles I use lee collet dies. I full length resize all once fired brass in an RCBS die; all subsequent reloading is with the collet dies. Greatly improved concentricity and improved longevity of my brass. Wish I had a set for all my other rifles.
