Nawlins Kid Posted November 20, 2015 Share Posted November 20, 2015 Recently I was able to purchase a 8 lb container of Claydot. I normally use Clays but I was getting low on powder. Yesterday the temp was around 60 degs. overcast with occasional sprinkling of rain, an anomaly here in Western NY in Nov. My Crony digital is 10 + years old so results may be different with a newer models. I used Remington primers and mixed brass. I normally use 3.7 grains of Clay's and 230 gr. bullet which produces around an average of 751 FPS. This come out to 172 PF The same load with Claydot produced an average of 737 FPS which is a 169 PF The next load was 3.9 grs. CD which produced an average of 777 FPS. which is a 178 PF. The last load was 4.0 grs . CD which produced an average of 780 FPS which is a 179 Pf The interesting thing was the Claydot had a smaller spread of speed ( in fact all three loads had duplicate speeds) than Clay's So ClayDoy can be use with Clay's data with a more consistent FPS Nawlins Quote Link to comment Share on other sites More sharing options...
Goatneck Posted November 20, 2015 Share Posted November 20, 2015 Kid Good info to know. the smallest amount of FPS deviation is the most desireable. See youall at the convention Quote Link to comment Share on other sites More sharing options...
Garrison Joe Posted November 20, 2015 Share Posted November 20, 2015 Yep, those numbers are consistent with my testing and use. I almost always find 0.1 or 0.2 extra grains of CD is needed to maintain exactly the same velocity as Clays in pistol cartridges. You will also find that CD is not cold sensitive like Clays has been. Haven't had a chance to test any Canadian Clays yet - all I have is Australian-produced Clays. Good luck, GJ Quote Link to comment Share on other sites More sharing options...
Nawlins Kid Posted November 21, 2015 Author Share Posted November 21, 2015 At the NY State WB last April my rifle load with 200 gr. bullet with Clays was effected by the cool weather we had. Since I never load at the minimum load I had no problem with the Clays meeting the PF. I will now be loading the 45 ACP with Claydot for now on.

docmccoy Posted January 19, 2016 Share Posted January 19, 2016 Thanks Nawlins. I won 8# of Clay Dot at Heluva Rukus and have been checking on it's use since then. I loaded a few test rounds that I have not yet fired. Getting around to it sometime this winter. Quote Link to comment Share on other sites More sharing options...
