Who has used br2 or in place of 200's with good results and little difference when changing between the 2? From pages of clutter with most agreeing on the subject they state they're both the same? Besides the "B" on the primer and more care taken when producing them they should be equal? Also according to cci's site they state the cups are harder and work fine in semi-autos (similar to #34's).

Have used both in 308 sized cases in bolt guns. Have not noticed much of a difference in them. Worked up the load with one and then changed them out. Not enough difference in accuracy to recall needing to change.

Concur. Use both in my 7-08 and 243. Not enough difference to select one other than BR-2 a little more money. I'm going to try them in my .280AI vs 215 and 215M
I spoke with a management "Person" in the Primer process. The "BR" stamped on the primer means that there was an additional QC process for these primers. They are basically the same without the 50% additional cost. $100 per brick vs $150 per brick.

I have run many tests with many primers. Sometimes the bench rest price are more accurate and higher velocity and sometimes the other ones are. The only way to know is to test them.
I did order those high priced br2's from Natchez, but only 2k. Delivered price was $412.66......OUCH! I ordered them for the 6.5prc prospect ar10 project. CCI states harder cups than 200's similar to #34's. I probably won't try them in the 45-70 and might also use them in the ar10 243win or any other ar firearm (260rem, 6.5creed and 308win). For the sorta short mag 6.5prc the 250's might not be a good choice, but I'll try all 3 (br2, 200 and 250's)? As far as 400's and 450's go the 450's work great in the 300bo with 296, h110 and lil gun.
Who has 308 type cases (260rem, 243win, etc) that has srp's. I've only seen Lapua and Starline offer srp's in 6.5x47, 6.5creed and maybe a few more. Other than availability of srp does it have good accuracy and velocity results?

Alpha makes .260 SRP brass. It is what I use for my .260AI. They also make .308SRP brass. Plus all the CM brass (22, 6mm, 25, 6.5mm), 6.5x47L (SRP only), and 6XC is available LRP or SRP.
As far as primers go, sometimes there can be a huge difference in accuracy potential. Almost all the rifles I have tried the CCI BR2s in have loved them.
My .260AI loves CCI450 and Fed GM205M, but HATES the CCI BR4s. This was a primer test from this weekend.

Well, it might not've like the powder primer combo.

Peterson also makes SRP brass for 260/243/308. I use it more often than Alpha because they make more case options, but both have worked well for me in the past.
