Full recoil test part 3 - Muzzle brakes

A third test of the practical recoil of a series of muzzle devices. The test measures the time from shot fired until the shooter is back on the target in a controlled manner. The target is 15cm (6") at 300m (330yds), so not too much wiggle room. We shot 6-8 shots per device.
The T.S.G Ymir muzzle brake is used as a reference so that you can relate to this and our previous test. The shooter was the same for all shots made and an effort was made to keep the same position behind the rifle for all shots. The shooting position was standing behind a skillstage on the top level to simulate a common PRS shooting position.
In this movie we used a 6.5 creedmoor shooting Norma 143gr projectiles. The rifle weights approximately 9kg.

The following devices were tested:
-T.S.G Ymir muzzle brake, perhaps the most common muzzle brake used in Swedish PRS competitions.
-A.P.A Fat Bastard gen 3
-Botnia Solutions Mini
-Botnia Solutions Midi
-Botnia Solutions Maxi
