They are not listed as hunting bullets, but should do for whitetails.

They sure are .451...well at least the 300gr Unicore soft point is smaller for sure. The pointy Harvester Scorpions are also. Those are the only ones i can load sabotless in my Elite 45 (perfect fit too). All the .452 will not fit without a hammer.

Some bullets made for 45 ACP are also .451. Parker Ballistic Extremes are even smaller at .450 but IMO a bit pricey, the Scorpions PTs are a much better value IMO.
Personally ive had the best luck in tight bore with the MMP 3 petal EZ or the Hornady low drags. Its probably the 3P MMP sabot but colored red. Combined with a .451 bullet they should load in any tight bore but will likely be loose.
Knight EZ load bullet and sabot combos also go down any bore ive tried and shoot pretty good even in a normal bore for me.
About the cheapest way to find out might be to use the Harvester black Crushribs and a Scorpion PT or the smaller Speer 300gr SP.
Im with Sabotloader on a good bore polish or you can try a less abrasive bore cleaner like ME Copper Cream or JBs milder option. Using any of the polishes made a big difference in loading pressure in my tight bores just dont over do it or use it too often. I only polish a new bore once with JB or ME polish.
