Quick responce, the bullet has to be under caliber to fit in and allow the sabot room to load, which is more close to the barrel measurement. others will have a better techno answer but this should aleviate your concern. Just make sure the sabot is the correct one for your rifle, the package will say what its for. Don't use a 50 cal sabot in a 45 cal rifle ect. I haven't experimented too much but my 50 cal TC triumph likes TC 250 gr shockwaves with the super glide sabots. Barnes bullets/sabots 50 cal have .451: bullets also shoot very well from the TC. Precision Rifle bullets 260gr utalize a 44 cal bullet in a 50 sabot their claim says open country shots out to 275 yds.
