My rifle seems to favor the 210 gr. bullets and it will put 3 Ballistic Tips into about .5. Now if I use the 230 FS it opens up to about 1 inch, but these are also coated bullets. I have a bunch of them so I'll be shooting those for a while. I would like to try other bullets like the Triple shock, but the 225g will be almost identical to the 230FS. I think I will try some other 210's, im not a fan of the Ballistic Tip, though they shoot very predictably. How many gr. of the 4831 are you putting under the 210's?
I use 75gr. of IMR 4350 under the 230FS and have tried 78gr. The 78gr. is stout and flattens my primers! I have some data directly from Dakota, but only for 200 and 250gr. loads
