250 Savage Ackley Improved Reloading Data needed

[cappi]

Just ordered a 15" barrel for my Remington XP-100 pistol. Any one have any experience reloading for the 250 Sav. AI ? 75 - 100gr. ?

I laaded some 100 gr ballistic tip [Nosler] and some 100 gr Speer Hollow points over the SAME powder/weight. The Speers went 5 shots into about 3" at 100 yards. I thought I was in trouble. Then I shot the BTs,,,3 into 0.2". Wow, never thought a bullet type would make THAT much difference.
My .250 AI is in a Shilen CM barrel [24"]fitted to my Ruger Mark II short stainless action.
Doe at 165 yards last year. Great deer/coyote rifle.
