Re: 25-06 vs 25-06AI

Like I said earlier, I personally would defer all questions to Nitroused383 as he has "been there, done that" reference this cartridge; and didn't forget to write it all down.


Isn't a 383 a .060 over 350ci block with a 400 crank...or is that a 377? Maybe I got it backwards, 060 over 400 block with a 350 crank. It's been awhile and quite a few hobbies ago.

Re: 25-06 vs 25-06AI

I always like the 327 just a bit better. 327 / 375 from a corvette and then had it balanced and blueprinted by a Japanese guy named YUK who lived in Omaha and dropped it into a 66 SS Nova. SWEET. Didn't corner worth a dam but boy would it go in straight lines nice. Use to buy 100 octane gas for $.45 per gallon and it would even do better with that. Hmm Memories.

Looks like I need to load up my ammo and head for the range with it. 383, how much jump were you seating to when you got that pressure spike.

I'm not claiming to know anything really haha. I just have shot about 300-400 of these 115 VLD's through my gun looking for the perfect load. In the past I did a bad job of recording data so I often forgot what I had tried / tested before. This time I collected the info I could along the way and I tried to keep all my targets. 383 is a .030" over 350 block with a 3.75" crank (400 crank). A 377 could also be a 400 block with a 350 crank.

I love the Chevy II's ! 100 octane gas for $.45 / gallon? That was way before my time I'm guessing Seating depth as stated was a .040" jump from the rifling.

Im using 100 grain ballistic tips right now until I get bored with them but with 58 grains of 7828 I chrony'ed them at an average of 3400, I think I could go a bit warmer but I can string 5 in a dime so Im pretty happy with that. As far as throat erosion goes leaving time to cool between shots and keepin em clean goes a long way, but hey, they put threads on barrels so they can be removed and replaced. I always joke with people and tell them " I have a job that pays me with money with which I can use to buy new barrels"

Re: 25-06 vs 25-06AI

I had a 383 in a 69 Coronet, more or less stock other than the 2" straight dual exhaust I had put on. It wasn't much from the hole but the top end was more than a few of my buds wanted to hang with. I really like it switching into third around 95 and then the body wold raise up, level off, and the speedometer would simply slap the far side or 120 hard enough to bounce back over around 90. LOL

Not sure what it was going, but it was pretty cool none the less. Oh yea, the High Octane juice REALLY made it shine.

Re: 25-06 vs 25-06AI

The best time in a 66 SS Nova is when the 69 Trans Am in front of you is topped out and you still have plenty enough left and you just blow on around him like he is sitting still. Just hope you don't have any curves.

I was just wondering 383 if you were right up against the lands which can cause a pressure spike and which can make a bit of a difference with just one grain.
Just a bit of info for the rest of you guys shooting the .25-06 AI. I found that neck tension was very critical when it came to accuracy with this cartridge. I also learned that if I annealed my cases each time I reloaded them this problem went away. I learned this while learning how to fireform cases without loosing too many by blowing out the shoulder during fire forming. Lost a few cases that way on my first attempt and someone on here advised I anneal them before fire forming which I did. Accuracy wasn't that great after fire forming and I thought maybe the case wasn't totally blown out so I annealed them again. Shot them and accuracy was back and on the next firing it went south again. So I annealed them once more and accuracy was back. So I just make it part of the loading process after that. I do it in the basement with the lights off and a curtain just open enough to let me see whats going on but still let me see when the case just starts to go very lightly red. I watch for this while rolling the case in front of a propane flame and with the case in a deep well socket far enough to protect the bottom half of the case from the flame and when I see it just start to glow it goes into a coffee can of water to quench it. Been doing this for 25 years on my .25-06 cases to keep them from cracking the necks and it works but didn't realize how much it could help the accuracy. Especially on a tight neck chambered rifle.

I was able to get almost 3100 out of a 26" barrel and a 140 nosler. I completely shot that barrel out and now have my third barrel on it. It's a 26" Lilja three groove chambered in my 6.5 Sherman. I can tell you that it is far the best of the three. The A.I. case holds about 6% more powder than the std. case. My Sherman case holds 11% more and the cases last forever! I'm getting up to 3200 with the 140's with great accuracy. I have a once used reamer that would like to do some more work. Let me know if you are interested......Rich
I have seen you post about your 6.5 Sherman. What is a 6.5 Sherman? I have looked for info and can only find your posts. Thanks
