Gavin,
Good to see your still looking down at the green grass or maybe at the brown sand at your location.
I chose that bullet for hunting more than long range shooting, so I went with the .432" diameter so I could patch it with paper under bore for shooting dirty for hunting and use a .002" thick paper for target. And it works great for both applications.
I found I got better accuracy with the twisted tail tugged under the wad to keep the wad from getting pushed down into the cup shrinking it away from the bore wall letting the gas blow by keeping the vertical down that I found just folding the patch like I would for a flat based bullet.
I found to many bullets with gas cuts just folding the paper and also the thin skirts with damage.
I also opened the garage doors and shot from deep in my garage to keep the patch remnants from the winds blowing them away checking what the difference was between the twisted and folded tails and both were close to the muzzle blast on the floor but the folded patch showed signs of gas cuts. Using the HDPE wads solved that problem because that polly is harder and it holds it's form.
