Have had great accuracy with 41gr working up to 44gr IMR 4895 and 200gr bullets of various makers--Nosler partitions, barnes old school copper, don't remember the others, but the Swift A Frame is one of the all time greats, and you will need all the premium bullet you can get for elk, as shots are not always ideal. I would pick my shots. Good luck! Oh!! ps...would also big time want to check out any offerings in Barnes X and Hornady X knockoffs by all means.
