Is there a primer of choice for the .338 Edge shooting H-1000 and 300gr SMK???
CCI 250 is what I use.
Here is a link to some load information from Shawn C:
338 Edge Load Information
Right now you can only load what you have access to, and for me that's Remington Magnum.
I shy away from CCI's because I have had a high percentage of them NOT fire. I have probably used around five hundred CCI's from several lots and had problems with nearly every lot. I have used over 10,000 Federal GMM with 0 problems from -20 degrees to 90 above.
I cannot speak for CCI's current quality as I have not used them in nearly 10 years.
I use the CCI's. They've worked for me so I had no reason to switch.
I"ve used quite a few CCI's within the last 10 years, from small rifle through magnum rifle and never had a problem.
Same here....I've never had an issue with CCI primers. Michael, maybe you should give them a try again. I know you said you had bad primers from various lots, but were they all around the same year? Maybe a bad year?
I switched from fed. match to cci 250 and cut my es almost in half.
Ok I'm gonna go with CCI 250's in the 338 Edge. Even though it won't be done till late next fall I ordered 5000 today.
i've switched to 215m primers from 250's and have a slightly better ES. don't claim to have run that many yet. was told by a handful of bench shooters the 250's are just not as consistant as the 215's. i'm shooting 250 gr bullets though. gonna try some Norma MRP powder when the weather gets respectable.
I really do not think it really matters. Your rifle will tell you which primer is best for it by reading the velocity spreads when you shoot over the chrono.
I have shot well over 100,000 CCI primers including CCI-300, 350, 400, 450, 200, 250, BR-2, BR-4 and CCI-35 primers. Of those, the I have only had one misfire that I can positively say was caused by the primer. That was in a 22-250 AI with a CCI-BR2 primer.
I have probably shot 30,000 Fed-215 primers and I have never had a misfire.
So I guess mathematically, the CCI primers produce more misfires in my experience, I guess.
I will say, the Fed-215 standard primer is a hotter primer then the 215M match version. For real cold weather hunting, the standard would be a better choice but to be honest, with the powders used in the Edge, generally easy to ignite stick powders, and not huge doses, 90-93 grains, any large rifle primer will generally work pretty darn well.
Again, check your extreme spreads and your rifle will tell you which primer you should use.
The only primers I have available right now are the BR2s. I am getting started on working up loads for the 300smk with my 338RUM. Will these work or just need to try it? The powders I have are Ramshot's Magnum, 7828, and I just picked up some H1000 and US869. Are any of these easier to ignite than the other?
I had the same results as dave, today i shot with cci 250's and fed gold medal match mag primers with 93 gr of H-1000 and 300gr smk's and the cci's had a spread of 13fps and the fgmm had a spread of 4 fps may have been a fluke or it may be like that every time, i hope its like that every time. I plan on shooting some more this weekend i should know some more by then.
You bring up a very important point even though you probably did not mean to. There is no one on this board that could shoot two loads at 1000 yards from field conditions and tell any consistancy difference weither one load had a 13 fps extreme spread and the other had a 4 fps extreme spread.
Point being, you should be able to work up a great long range load using any primer that will effectively ignite your powder charge. At least a load that will be more consistant then we as shooters can be at long range.
We often get caught up with looking for that magic load. Nothing wrong with that but often times we would be far better served just out taking field practice shots and moving on from load development.
Just my opinion. Also my opinion, you would never be able to honestly tell that one of your loads is better or worse then the other at long range. Both are excellent.
You will likely have no problem at all with IMR-7828 and H-1000 with the BR-2 primers. Ramshot states that their powders are designed for use with standard primers so you should be fine there as well but personally, I would still prefer a bit hotter primer.
US869 is not an easily ignited powder. Its also not the best choice for the 338 RUM. IT will work well in the 300 RUM with heavy bullet weights but is really to slow for the 338 RUM.
