Hello.
Im wondering if I should change powders. Im using AA2495 and i have one 1lb can left and i'm wondering if i should order more or try something else . The best load i found using a ptII have been 24.5g 2.335" sierra 69g smk. I'm using lapua brass and br4 primers. I have allot so i don't want to try and get different primers, the primers are kinda old too so that might be contributing to results. Im using redding busing dies and microseater, sinclair priming tool, wilson micro trimmer, and an acculab scale.
My velocities for that load are 2568, 2560, 2554, 2557, 2576, 2564, 2532, 2549, 2501, 2492
SD 26 , if i remove the two lowest numbers, which im not sure why those two happened and why they happened back to back then the SD is 12
The second best performing load was 24.8g. Velocities 2634, 2590, 2575, 2609, 2613, 2594. SD 18 , but the waves on the pressure trace are noticeably worse when compared to the 24.5, as are other charge weights.
Im using a cle chambered 16" 1:7 douglas barrel. I understand there are similar posts to this. I'm sorry. I like the 69's and i don't want to switch to the 77's or 80s. Thank you for reading.
