if your going to use core lokts check out the new remington whitetail pro core lokts. There still basicly the same thing,but have better standards in production and they aint as dirty.Price is still way lower than alot of other ammo. I myself use hornady in my lever gun and hand guns.My deer rifle is a browning A bolt in 270 and I use 130g winchester silver tips. No problems unless shot is real close then they dont do there best, still going way fast.But still no problem DRT. Also remember it aint the ammo you like,Its the ammo your rifle likes. some rifles or very picky about what they eat some not so. If this is what you think you want to use get a box head to the range and see what your rifle has to say
