do you guys use the harris benedict or a different one im designing my new diet and the harris benedict puts me at 3800 cals but the one i used accounts for activity and lbm and puts me at 4100 cals which one is better for the real bmr? which one do you guys use

The harris benedict calculator does account for activity level. Thats the one I choose to use when designing a diet. I do however, plug my lean body weight into the equation instead of my total body weight when designing a cutting diet.

if you do lbm only wont the calories start out to low right off the bat because the unaccounted for mass will eat up the cals you set for the lbm or no?

Depends on how low below your maintenance level you set your daily caloric total at.
On average, you would only be talking about a difference of 20-30 lbs of useless bodyweight in the form of fat, so no, I don't believe this would have any significantly detrimental effects. Some may have a different opinion.
