DR Loads: The Nightmare Returns

First topic message reminder :

I legged out with my S&W Model 14-3 using 3.2 grains of Bullseye, CCI primers, and a 158 grain LRN bullet I cast from wheel weight lead using a Lee mold - the tumble lube design. Shoots good. Good enough to do alright but it takes hard work to shoot it well at 50 yards. Feels peppy in the hand. Makes me wonder if I could be shooting a better load sometimes though. 

I've done some reading and see people have had very good results with the Remington ammunition (advertised velocity of 755fps) and the Federal/American Eagle ammunition (advertised 760fps). Some people even mentioned having good luck with Magtech ammunition (advertised 750fps). The Atlanta Arms PPC Match ammunition shoots great out of my gun and is advertised with a 730fps velocity .. give or take of course. So I wondered .. how fast is my 3.2 grains of Bullseye load moving? I'll say this much; my load feels like it's got more punch than the Atlanta Arms ammunition so I wonder.. maybe my load is moving quite a bit more. 

So I consulted my several different loading manuals first looking for some idea of a neighborhood or ballpark guess as to where I might be. I have other books but these three for example are as follows:

*Lyman 49th says 3.0 grains of Bullseye should do 786fps 
*Modern Reloading Second Edition Richard Lee 3.5 grains of Bullseye should do 884fps so if my math is anywhere near correct in theory then 2.9 grains of bullseye should be close for 750fps... maybe ..???
*Hornady Handbook of Cartridge Reloading Third Edition says 3.2 grains of Bullseye should do 750fps

I'm not seeing much consistency in the data here but there are a lot of things in question too. Test gun/barrel fixture? Barrel length..? Crimp on their ammo, seat depth, primers even and what type of bullet. 

So the next thing I'd like to do is chrono my loads to find out where my loads are at exactly. Make it a data point and not a guess. I don't know when I'll find time to do this but it's on the list. 

Afterwards, depending on the chrono results I may entertain the thought of trying other loads but I'm already busy with testing for two rifles and another revolver so... I need to get those projects done first I think. Not sure. 

If anyone has any thoughts to add on this one come on and weigh in.

I’m getting some failure to fires in the revolver with CCI primers. I’m going to be switching to Winchester as I’m told they’re softer and easier to bust in a revolver. A question though: are CCI primers hotter, the same, or burn less than Winchester primers? I will be sandbagging my load again with Winchester primers to see if there is a change .. I hope not.

really federal are the go to revolver primers for me, but Winchesters work fine
