I've been shooting mostly 55gr nosler ballistic tips in my 22-250 over 36.5grs of Varget and a WLR primer. That load is safe in my gun but may not be in yours.
Was at the range last week and found the BT's aren't shooting as well as they did.
But, 55gr red prairie bullets still do.
They used to be made by Starke Bullet company. They stopped making the RP bullets and sold the machinery to Wildcat Bullets. Contact person for Wildcat Bullets is Richard.
Email him for pricing.
