My sons and I have been shooting my 25-06 AI for awhile now and have been impressed with these 131 blackjacks. I actually had this barrel made for my tikka awhile ago and couldn't find the bullets so when it did come in stock I make sure I had enough and a little more just in case. I've never seen them in stock again since then. I let go just over 600 pcs to members to help hold them over and it seems like they won't be made till ending of the year or worst in early 2022.
Anyways I've made one load that shot under 1/2" @ 3160 FPS that settled in at 3198 FPS so I left it. I couldn't find any blackjack info for a 25-06 AI so I will be making a thread to help others in the same boat or curious in making one with a load ladder and load development with several powders. There are many other cartridges that are faster, better, with better brass and what have you but finding components to make a 25-06 AI has been fairly easy well except the blackjacks but hopefully it will ease up in the future. My rifle has been easy to shoot, hits like a hammer and has kills on sheep, goats, deer, pigs and wild cattle. I've shot elk before and I must say these big wild cattle closely resemble them structurally. I was surprised how this little bullet kills them instantly from close to far, penetrates deep even on quartering shots. My sons and I have not lost one yet or have any run farther than 100 yds. A 257 wby is next for load development and I hope to get 200 FPS or more over the AI. I've got a bunch of 270 wby brass I will be using.
