Hi Stephen, I shot with Jerry in the mid 80's, heck of a guy. Not many people ever shot the lighter bullets in the 6PPC. I made bullets as light as 40g on a .750 jacket shot at 4000+ fps in a 24" Hart bbl, and they would have been very competitive, 8s ojive with a .070 meplat, and FB.. The 50g bullet shot at 3800 fps was awesome also, all shot with h335. It takes some trial and error with various sizes of punches to get the cores seated correctly. The bullet jacket gets thicker toward the base, and a smaller dia. punch must be used to seat the cores on these lighter jackets correctly.
I consider the most accurate bullet,100 yd shooting) that I made a 60g BT on a .750 jacket, with a full point up, .070 Meplat jammed .030 into the lands. It took a special throat to shoot this bullet, but at 100, I shot more zero's with it than any other bullet that I ever made or tried with a slightly compressed load of H335.
I think that my load was 31.5g of H335 with a CCI BR-2 at 3600 fps out of a heavy varmint 24" Hart barrel with a short throat.
Copper fouling was non existent due to the minimal bearing surface of this bullet. My bullets had a .2433 body with a .2436 pressure ring on the flat base bullets.
If more guys shot the 60g Sierra HP in their 6ppc, it would shock the shooting world at this bullet's accuracy. I talked to the head tec at Sierra about it's accuracy, and he said that it was the most accurate bullet that Sierra made due to the size of the "coin" that was cut to make the bullet jacket...really don't know what/how that contributes to the accuracy. I do know that as the leade gets worn in barrel throated for the 68's, that the additional bearing surface of the 60g Sierra helps get the bullet started straighter in the barrel compared to my longer-pointier bullets.
In the mind set of a lot of informal paper punchers, as the bullet starts to jump in their chamber, they consider the barrel shot out. For some reason, the 60g Sierra seemed to overcome this inaccuracy problem caused by more bullet shapes with longer ojives. My conclusion was that the more pointier the bullet was, the more important it was to touch,jam) the lands. I had one 14 twist Hart barrel that I put 10,000 rounds through using mostly 60's with 335. I really abused this barrel on p. dog towns cleaning only after firing 300 round strings,waxed bullets were used) for over 8000 rounds, it was considered a test barrel. At the 10,000 round mark, I though that I would shoot 18 groups to see how the barrel would agg, well it agg'd .287 for a total of 18 gruops shot over a period from 9:00 am to about 3:00 am. I was having fun with my shoot'en buddies at the range that day and only put up one wind flag.
I would like to mention that for an informal paper puncher, that in my experience, H335 will double the barrel life of a 6 PPC barrel compared to any version of 322...don't know why. The faster lot of 335 that you can get your hands on, the better & more accurate it is. Some years ago, there was a lot of 2230-S that produced spectacular velocities with extreme accuracy. It made the gun sound like a cannon going off, we named it Chineese firecracker powder!
Much talk is always of bullets, powder, and loads. We should not forget to mention encouraging new and informal paper punchers in the use of wind flags and targets with mirage bars on them, because the ability to read the wind and Mirage is at least as important AS finding the right load.
