Conical for Knight LK-93

[woods89]

I have a Knight LK-93 50 cal that I am planning on taking to Colorado in 2019. I am wanting to start working up a load but have a few questions.
I've deer hunted with it some here in MO and used sabots. Accuracy was good enough but not great. Last year I tried some conicals that a local place had (Black Widow bullets, I think). They fit very loose and accuracy was terrible even with trying different powder charges. I have been interested in the No Excuses bullets and would like to try them.
No Excuses come in 3 different bore sizes. Anybody have a recommendation for this particular rifle? Any particular bullet weight? Powder is T7 fffg and ignition is no. 11 caps.

I only shoot conicals in all my guns and all of mine shoot well with the no excuses. I shoot the .503 495 grain in all my 50 cal guns with 777 fffg start at 65 grains by volume and work your way up to 90-100 grains then shoot whatever load shoots best in your gun.
