Re: subsonic d46?
If you are wanting expansion, accurate, available plus less expensive, I would highly recommend you check out the Hornady 170gr FP part #3060 or 180gr RN part #3075, now these are 30-30 bullets however they have thinner exterior cooper jackets, softer interior lead cores and are designed to go SLOW from the get go. Loading these with Trailboss powder and obtaining .75 - 1.5 moa across the board depending on mostly weather. The slow twist barrels are also more finicky compared to the 1/10" as well so load development is critical of course, hope this helps.
