Peterson .243 Win. SRP Brass

[South Pender]

Now that Peterson has introduced the SRP (small primer pocket) brass in .243 Win., I'm wondering whether anyone has tried this with their .243s and has compared accuracy with the more-usual large primer brass in the .243. I'm curious about whether use of small rifle primers produces better accuracy than the large rifle primer brass in the .243 Win.

Can’t speak for the Peterson in .243 but I have Peterson in LRP & SRP in 6XC. I shoot the same load in both of them and can’t tell any difference in the accuracy.

I tried it with a top charge of N 165 ,CCI 450 ,Bart Hammer 105 grs . Accuracy was great ,just over an inch at
520 m ! The speed wasn't great trough a Krieger 32" (3120 f/s) but accuracy was outstanding ! I highly
recommend using a single base powder like N 160 or 165 for SRP , the double base are not so easy to ignite
with this case capacity .

I have used The 243 Peterson SRP brass and it shoots the same accuracy and same load as my lapua brass with H1000 and 115 Bergers.
