Depends on what you are using it in, and how you load.I have always used CCI large rifle primer however I have a chance to purchase Match large rifle primers at a good price.ill someone tell me the difference.
When I was shooting hunter class and cast bullet benchrest competitively, I tried CCI BR and Federal 210Match primers (and Remington 7 1/2 in small primer cases). Benchrest shooters have been known to be 'a little anal' about their beliefs, equipment, and practices, but I 'believed' they made a difference, could have been as much a placebo effect, but as long as I thought they were 'better or more accurate', that was good enough for me. When you look at, and study, a bunch of benchrest match results, both who won and the equipment listings (mainly national big matches with travelling shooters) there is a lot variability in the finishing ratings/positions (meaning 'trading places') from match to match among the 'regular' top finishers (say top 20 to 30 shooters). This has led me to conclude that, while 'talent and equipment' certainly plays a major role in repeat winnings, there is a good deal of serendipity at play as well.If you have a 'match' rifle, you might tell a difference but it could just be the phase of the moon.
I use the federal Match LRP in my 45-70 & my 30-30 and noticed a difference in the group sizes when I was sighting in my scopeI've used CCI BR4 and Federal210 M and can't tell a big difference in accuracy, maybe a little. I agree every little bit helps if your shooting for utmost accuracy.
There is supposedly more consistency in the manufacturing process of the Match primers. I have used both in the same load recipe, mostly with 30 30 loads, with absolutely no really noticeable difference in accuracy. That has been my experience anyway.I have always used CCI large rifle primer however I have a chance to purchase Match large rifle primers at a good price.ill someone tell me the difference.
The CCI's were stamped with a 'B', If memory serves (I still have some, but am too tired to go down stairs to dig them out to confirm!). I had never heard the 'new die' story. It seems to me that the 'B' stamping had to be applied somewhere during the cup formation process , and not on a 'final' primer product. If I'm right, that pretty much eliminates the premise that the CCI match or benchrest primers are the result of better/more consistent lot testing (no?). My benchrest preference was Federal 210M and Remington 7 1/2.We can't control the quality of primers so we spend a little extra hoping it helps. Many years ago, CCI said 'Match' primers were the first primers from new dies and overall as good as they could make them.
Anybody remember CCI Match primers being marked with an embossed 'm'? I think they quit that when magnum primers were introduced.
