I now have 2 bolt guns in 6 Creedmore. I found a very fine load with RL19 and either 105s or 108s to be very accurate at 100 yds. Problem is that my Harrell powder measures (I have 2) don't like to drop consistent loads of that powder. So, has anyone had fine results with a ball powder and those bullets? I know the fav powder is H4350, but hard to get and burns hot, so I'm trying to find something to equal it but cooler burning and easy to meter. BTY, my starting load in RL19 in my 26 inch barrels gives over 3100fps and groups in the 2s. So if I can't find a ball powder to equal it, I still have RL 19 but slow loading. Help!
 
Aren't ball powders temp sensitive? I think n150 is a ball powder, should be around the right burn rate.
I'm sorry, but I have to add: it's spelt creedmoor.
Happy shooting
 
hehehe, "spelt"? And my bad, you are correct in the spelling of Creedmoor! And as for Superformance, I have tried it and maybe I should go back to further testing. My one load grouped pretty good, but the ES and SDs were pretty bad at 72.83 and 36.68, respectively. Speed was also a tad lower than the others so I could add a 1/2 grain and see what happens. It does meter well! Thanks guys!
 
Burn "rate" is shown in most reloading manual/books. But I think that is slightly different from burn "temperature". Not sure, but a guy on Snipers Hide forum shows a list of powders and their heat which he relates to barrel wear. I found it looking for loads for the 6 Creed. Have not compared his list to burn rate charts, though. Could be the same.
About ball powders: Superformance is a ball, I think, or at least a small flattened ball, and I thought it was touted as not temp sensitive. Right?
 
Correct Superformance is ball. I don't get wrapped up in the temperature sensitivity stuff. I do my load development in hot weather; only use safe loads; and have turrets on my scopes to adjust the cross hairs when going from 90* to 30* shooting sessions.
There are just too many other variables:
A missed 5 mph wind gust,
2 grain difference in the case capacity;
hand pressure on the forearm, etc, etc, etc.

I used ball powder at one of the Allegheny Sniper Challenge matches year ago, where they supplied the rifle, scope and ammunition. The .308 Win was loaded with BLC-2. It shot very well for good shooters.
I have shoot (hit) prairie dogs out to 550ish yards using .223 with ball.
US Military has used ball powders for decades.

Pick a safe load and practice.
