If you haven't opened the package yet, well.. you may want to go exchange them for some Shockwaves or SSTs.

Your Knight bore is slightly oversized & your Barnes Spitfire 245s generally run quite undersized... unlike the 250 gr Barnes Expanders.

Why Barnes chose this bullet diameter for the 245 grains... I haven't a clue. My Omega is known for a tight bore & the Barnes fit nicely.

Just my opinion.... take them back for some 200 or 250 gr T/C Shockwaves.
