Bracketing is the least useful and least accurate method of rangefinding for me
. and I only use it after trying at least three other methods as a last resort.
What it will do is confuse you and slow you down, and you will rely less on your instincts.The only time I use it a bit more is for mixed FT/SFT/HFT 55 yard courses, and only if the targets are fairly standard.
I shot better a few weeks ago on the Emley extreme when I didnt bracket at all. Maybe I should not do any braketing in future.
