Blow-tubing

[Old Jim]

At the range yesterday, I had a couple of test loads, Old E 1.5 and a new lot of 1.5 Swiss. Bullet is the BACO $ bullet, 525 gr., 0.458 in the 45/70 Shiloh.

Humidity was 50%, 6 o'clock tailwind at 4mph. Target at 200 meters.

Started with 5 blows for first 5 shots with Old E, after 5 fouling-shots. Vert. = 5", horz.= 1". Rethought first shots, cleaned bore, fired 1st 5 again, same blows, same results.

Switched over to the 1.5 Swiss loads , 5 blows again, 5" vert. again.

Tried 4 blows, 3.5" vert., well now!

Tried 2 blows, 2" vert., 1" horz., dang!

Switched back to Old E loads and got the same results!

Could the Old E and the new lot of Swiss be close in fouling control? Appears to be.

More trials and tribulations to follow later,

Jim
