Get a sample package from Dan at Bull Shop - I would try a few of all his .451 offerings - but do as goatbrother suggested and make sure you order the correct diameter. Dan will make you up a package with a few of each and price them very reasonably. His 488 grain bullet was sent to me for testing, but I never got around to it so sent them on to Batchief in Indiana for him to test. Batchief should be testing them shortly. Willjust about guarantee that bullet will be a great performer... but healthproblems, phase of the moon, rectal lead deposits,and too many other rifles that need shooting kept me from trying them.
