RancidRabbit Posted February 12, 2017 Report Share Posted February 12, 2017 How much difference is there between the BR primers and the standard small rifle primers? Ive heard some people say that they are the same except the BRs have met higher production specs. Link to comment Share on other sites More sharing options...
gbal Posted February 12, 2017 Report Share Posted February 12, 2017 Lab tests tend to show consistent 'flash' differences between brands-and eg BR/Magnum/ standard primers. Mv measures too show differnces. Laurie here has done extensive testing,for sound practical implications. All that said,there is not complete uniformity in the correclation of these measures (flash/temperature etc) and actual target performance. There are also brand variations in whether the 'premium' primers offer consistent efective benefits. Let alone \cost effectiveness'-though that has to allow for differnt needs/standatds etc...and costs! So,there are differnces,a little room for 'only better production specs'-whatever that means,but fairly reliable differences too,that the prudent shooter (whatever that means!!) had best not ignore.... :-) The right 'grade' of primer seems sensible-check out what the top shooters use. gbal Link to comment Share on other sites More sharing options...
nicklock Posted February 14, 2017 Report Share Posted February 14, 2017 I've used CCI BR-4 and Murom KVB 223M, and with my skill-set I can't see the difference. As a Yorkshireman, there is however one difference that's apparent... Link to comment Share on other sites More sharing options...

They batch test or quality control each batch. The batches with the best performance gets branded as "Model X Premium", the worst performance ones branded as " Model Basic Plinking" and every thing in between as "best value performance". In an ideological world every item in every batch would have exactly the same performance. I was not sure whether there are any design difference between standard primers and the bench rest variances Link to comment Share on other sites More sharing options...

In an ideological world every item in every batch would have exactly the same performance. I was not sure whether there are any design difference between standard primers and the bench rest variances RR best google "Rifle primer flash tests" Idon't know how a'prod batch could be tested for better than spec manufacture-but the tests will show I think that reputable makers have differnt specs for the different grades of promer they make-though there is not absoluteuniformity between makers. But 'all in one batch' then sort out later isn't how they are made.Ofte they cant be distinguished externally-eg in softness of copper.Using a box with BR on it won't (normally) transform groups-if only- but there are real gains in matching primer type (ie specs) to cartride,sometimes,and conditions (extreme cold-but rare in UK-in consistency ( seldom though does only one primer absolutely dominate what the serious guys use-but see Precision Rifle blog-what the pro's use-primers. There is some science,but when I was about 10,iIread the guru of the day (early 50's) -Warren Page- "it's differences of opinion that make for horse races"-one of the earliest "horse for courses" insights. ...and yes,I've heard the club 'experts' say its only a matter of picking out the good ones.(ask them how-and how did differences get there?...but be gentle....if they say "Six Sigma",have a look at their targets -bench rest ie sub .25 moa for every 5 shots?....if yes,listen. :-) Look esp at Laurie Holland's "ultimate LR primer test' Accurate Shooter bulletin june 3 2015 and James Calhoun "Primers and pressure' Vaarmint hunter oct 1995 Should give you the answers. g Link to comment Share on other sites More sharing options...

Big Al Posted October 27, 2017 Report Share Posted October 27, 2017 CCI BR4 is my 'go to' primer for the BR/Dasher variants. I can't think of a time when my accuracy or ES has made me feel like a change was needed. Link to comment Share on other sites More sharing options...
foxyloxy Posted October 27, 2017 Report Share Posted October 27, 2017 What Big Al said. I've had brilliant results with BR4's & i dont plan to change. Link to comment Share on other sites More sharing options...
henryo Posted October 27, 2017 Report Share Posted October 27, 2017 CCI 400 has a thinner cup I'd stick to 450 or BR4 (apparently hotter) in this cartridge or alternatively Rem. 7 1/2 Link to comment Share on other sites More sharing options...
