this is weird... before i could find my optimal load for my gun... i tried different combinations... 1. n320 4.2g 124 conical head (balagbag) 2. n320 4.3g 124 conical head (mas balagbag) 3. n320 4.2g 120 semi wad cutter (good pero low sa chrono) 4. n320 4.3g 120 semi wad cutter (havent tried this, next load ko) all are copper coated heads... the question is: someone gave me 100 rounds of i dont know what load but what i can say is that the heads look like the 124g conical and is made of lead (no coating) the recoil feels like the n320 4.2g that i have been using. but it stinks much much much more than what im used to. it smells like teflon the bullets made perfectly round holes in my target... i dont get it... the copper coated ones should be more accurate but in my case, not... what could be the cause? with the smell... is it with the powder or the head? thanks!
