This might be slightly silly but I have a 300 Norma Mag and a fairly decent supply of 125gr Nosler Ballistic Tips. Normally I use the 125gr BTs in my 308 to very good effect. Just wondering if anyone has been adventurous enough to try such a light bullet in the 300 NM? There is no published data on the internet. The lightest bullet I could find data for was 150gr and some of that published data says a 150gr will run at 3500 fps.
