i have the omega and i like it,yes it is designed for the 250gr sw and 150gr powder but the fact is it works great with any powder bullet combo you just have to dial it in for your setup thats the idea behind the bdc reticle i shoot 100gr of triple seven and either 300gr barnes mz or 300gr sst and the reticle works great its alot better than guessing hold over on a animal
or not shooting at all
