Range Report: Bartz Upper loves 300 Grainers

**Hoot's Note: I've been struggling with finding a cloud based image storage site that is forum post friendly, IE "<img>"URL"</img>". Though generous and easy to use, neither MS Onedrive nor Google Drive have directly linkable image addresses that anyone besides me can see. I have set up an account on Postimage.org to try. Unlike my past experience with Photobucket and its subset TinyPic, Postimage says it will not delete images due to inactivity. In the past, many of the images I worked hard to make and post for your benefit have died because they weren't visited often enough using the two aforementioned services. If you find images that do not work in my threads, let me know and I will try to revitalize them. TANSTAFL...Hoot

We're all drawn to our successes but less so, our failures.
Despite doing my 230gr FMJ tests which went poorly before this outing, I'm publishing this first since it went much better. All the loads tested in this session had room for more oomph, some displaying signs that they would do better accuracy-wise at a higher velocity. Since I was characterizing a new bottle of Lil Gun, I started a little lower, a little slower, working up. Never assume a load using Lil Gun will remain the same recipe from bottle to bottle.
While I'm at a loss to explain why the Bartz upper would make a difference with the 300gr Speer DeepCurl loads, it definitely outperformed my previous efforts across different brands of 300 grainers and across different powders using my original Bushy barrel and later, the Franklin Armory barrel. Not only was I able to get them to shoot pretty accurate, I also didn't run into cycling issues as I ran the charge up, like I did previously. No case head imprinting, no swipes, no short stroking, however I began to see slight primer flattening at the top load, but no significant casehead growth was measured afterward.
Here's the loads tested:
to save on space, I mixed like targets together. Here's the 225 FTX's (I adjusted the scope upward after the first group)
Then the 200 XPB's (They definitely wanted more gas)
and lastly, the thundering herd, 300 DeepCurl's
Now, for some humility, I'll finish the 230gr FMJ Range Report
