Very interesting post, and shooting the 30/30 with iron sights certainly is precision shooting. My 30/30 results don't mirror these, I had a Browning Trad. Hunter single shot(1885) in 30/30, so pointed bullets were on the agenda. When all was said and done, the Lyman 311041 cast bullet was most accurate, and least expensive to boot. Now I have a new Marlin 336 30/30 to wring out, and so far nothing shoots good in it!! The Micro-groove rifling is what I am blaming it on, but I will shoot this gun all spring. but won't bother with pointed bullets as i see no advantage to them in the .30 wcf. IMHO any advantage the ptd. bullet has is easily trumped by the thump of the flat point bullet and reliable expansion.
