Just bought a bench gun in my favourite calibre for a real steel. Remington 700 action, Leupold 2-12x VX6HD, complete with RCBS press and Redding dies.

Recent experience with a 303/25 proved a 100gn RCBS powder coated boolit can be driven to 2848fps with no leading. I'm hoping this rifle can do the same or butter with cast boolits!

wow, that things shweet.
What a beautiful stock and gorgeous rifle overall. My 250/3000 (not AI) absolutely loves cast 87 gr boolits from an old Lyman Loverin style mold and 103's from an old custom Saeco mold. My rifle is a T/C Encore.
Old post I know BUT… inquiring minds wanna know - How did the 250-3000 AI do with cast?
I assembled 40 rounds with a RCBS 100gn GC and powder coated. I chronographed these at 2,680fps average. I had some feedback from a shooter hunting wild hogs with his 303/25 and the same 100gn cast boolits were very effective on game.
Accuracy at 100yds was 1 1/2" for 5 shots and regularly rang a 6" steel gong at 200yds (9/10 hits) and I called the pulled shot.
Overall, they won't replace the gilt accuracy obtained with jacketed boolits but they do provide a cheap and affective alternative for general practice.
I got that mold and am hoping for some “good vibrations” from it!
My 25 line up starts with .25-20 Win (not holding my breath on that combo) and also includes .25 Rem, 25-35 Win, 250-3000 Savage, .257 Roberts, .25-06 Remington (perhaps) and the rocket ..... the .257 STW (not on a bet, LOL)
You could say I like the Quarter bores!

Thank you for the report!
1 1/2” accuracy at that velocity seems very reasonable to me for a cast boolit. I’ve had very good results with a hollow pointed 257464 (89gr) and Unique in an old Savage 99 with the 1:14 twist. I don’t have the RCBS 25-100 mould but I do have an NOE 260-105 which is kinda similar. Sadly, the 1:14 twist in the 99 just doesn’t allow for much accuracy with longer boolits.
I was considering the idea of building a bolt rifle in 250-3000 AI and using a 1:10 twist in the hopes of stabilizing the longer boolit/bullets. How was the accuracy with jacketed bullets?
Very nice ! When I can find suitable and affordable Marlin 336 in 35 Remington I am going to rebarrel to 250ai. Already have the finished McGowen barrel, dies, brass, etc.
