[QUOTE="Michael Eichele, post: 369411, member: 1007"] Len, There will always be a harmonic shift in the barrel changing from a brake to no brake even if you have a thread protector the exact same weight unless the length and proportions are the same. In other words, a thread protector may weight the same as the brake but unless that weight is the same amount of distance from the end of the barrel, it will be at least slightly different. It is not just the weight of the accessory on the end, but also it's position. Even if you could get this all worked out which would be very difficult due to all the holes and subsequent distribution of that weight due to the holes, there is still the factor of the gasses smacking the *** end of the bullet differently. At the very least, you will have a POI shift if not a MOA size increase or decrease and probably both. The best thing is obviously to develop your load(s) either with or without your brake and test them with the opposite. You will see first hand how easily things can often change with just a wee bit of difference in either weight, gas distribution or both on the end of your stick. If you are really lucky, these effects will be very minimal. [/QUOTE]
