Hal's 370NM .410 with #10 TSS

Post by GLS » March 19th, 2018, 1:45 pm

I ordered a couple of pounds of TSS 10 from Hal in order to try his new load out of my Yildiz single-shot using brass hulls. I could shoot to the end of my turkey hunting career shooting 9.5 and 13/16 oz. (355 gr). What would 55 or so additional pellets do in the 370 gr. load that the old load wouldn't do? Well, I loaded up a few to see and headed over to Floyd's to pattern and zero the gun for the upcoming season. I shot one round and it printed low, low enough to re-zero which was easy enough to do. The pattern looked great. I took it home, used a clear pot top to trace the 10" circle and counted. Damn. 131 in the 10" which was about 30 less than I was getting with the 355 gr load with 9.5's BUT outside the 10", it was pretty dense. A keeper for the upcoming season's use. At lunch today, I looked at the "ten" ring and it looked small. I measured its diameter--8". I used the wrong lid to trace. I tried the compass trick using a ruler and felt tip, but the drawn ring was larger than 10" . Wait a minute, the 10" top is in the pot cabinet. I retraced the 10" circle--62 more pellets and outside the true 10" ring, the pattern looked good for an inch or two more annular ring for an accurate total of 193 in the 10" at 40 yards. The 8" ring has only 64% of what the 10" ring encompasses. And has been noted, the 10" ring is only 25% area of the 20" ring. Boy Blunder at work....

There's a joke there about pots and smoking but I'm not the one to put it together. Looks good!

What diameter was that choke tube?

Not sure of the choke geometry or diameter. It was the first screw-in he made for the Yildiz. He had previously sleeved a choke into the muzzle on another gun I had him build. William made several changes while I was at his shop testing it. It extended .75" out of the muzzle. Newer versions aren't that long but do very well. I had one made up for a buddy and it's lights out in the 10" at 40. Gil

You need to invest in one of these. They're great, and your wife won't complain about getting Sharpie on her pots and pans. Great pattern btw

That price seems high considering what I've paid for similar in the past at a local glass shop. But, then, I'm the sort of cheapskate to cut something out of cardboard.
