I have two pounds of the 5744, so I intend to shoot that as my powder back east here (Va and NY). Some say it is dirty, but what is dirty in a smokeless? I have not seen the wild flyers, and my groups do open up some as the barrel heats up, howeverbecause I have shot mostlyin the cooler AM from 9am to 11 and only 20 shots ma. Shooting only 20 shots with a good 5 to 10 minture wait between sets of 5 shots gives the barrel time to cool. I have never shot a hot barrel, I have shot a warm barrel and I always check back where the powder is going off not the end of the barrel for this warmness. It usually takes 10 shots before it gets warm.If I was shooting all day with say 50 shots I believe after 10 shots, I would have to wait the 10 to 15 minutes. Like I said above, I am not chasing accuracy as a pure science with the Savage, like some do on Doug's Savage Board. I am chasing excellent hunting accuracy, which to me is 2" at 100 yards. Both bullets, Barnes Origonal and Barnes Flatnose #45843 did that for me with a CR sabot, the Flatnose was shot the first 5 shots and the 66g of 4198 was shot the last 5 shots, and it was a nice group. I am also watching Wilmeyer's experiments of shooting Sabotless in the Savage .50 cal, he is getting some acceptable accuracy with Kurling and a wad under the load. Thanks for your comments.
