According to both my experiments and the numbers using the formula for twist to bullet length the 1-28 and the 1-24 should do quite well with the 41 cal 210 gr bullet.
The 1-20 twist figures out to shoot something like a 38 caliber 210 to 240 gr bullet or a 250 or 275 gr 40 caliber bullet depending on the construction of the bullet we are talking about lead jacketed bullets here the brass or copper bullets are longer for weight so would be lighter at the right length. { just my 2 cents}
