Designing the 2-diameter paper patch bullet.

[Distant Thunder]

Don,

You would sure be welcome to join us any time you can. I would enjoy more time discussing ppb with you. I'd like to hear more of your thoughts and efforts with 2-diameter ppb.

I've spent so much time at Lodi over the past 20 plus years that it feels just home. Great place to shoot and Mark and Cliff have done a good job running the matches thru some difficult times for BPTR.

I did some looking at the .40 caliber twist thing and my feeling is 1.330-1.340" is probably the sweet spot. However, I believe with a round nose design you can push that length a bit longer. I have no idea how much longer.

My bullet at 1.250" is on the upper edge for an 18-twist, but has shot very well out to 600 yards. In May at the Lodi mid-range match I had the highest score after the two day match, higher than all iron and scope shooters. I was shooting scope because that's the way I set up this rifle up for silhouette. Because there were only 3 of us shooting scope and they require 5 for awards, my score kind of got lost. I'm ok with that, I just wanted to see how the load/bullet was actually shooting under match conditions and paper tells me so much more than silhouette or benching it at home at 200m.

I don't really shoot for groups anymore, all of my shooting is at matches. There's just isn't not enough time. So I'm very interested in your efforts with your bullet which is similar to mine. I really like that ODG nose shape and unlike some, I believe it is a good design for BPCR. It might require a few more minutes of elevation than the more pointy bullets, but that is just numbers. It just seems to me the more blunt bullets hold up better when things get twitchy and stay stable when the pointy ones struggle to hold on. I like 'em.
