Key to me it the thread the bullet shot for a brush gun. I have several of the traditional " brush guns" ... but would rather bet on a clear 3-6" hole and a solid rest than breaking brush.

Low power enough scope to give you the ability to shoot at close targets and get good target aquisition but clear enough - and with enough practice to thread the needle when needed. A good brush gun is a gun that you practice the hell out of to me.... Instinctive aiming, target aquisition, target framing and the shot.

I passed a shot on " blondy" a few years back in WY, a large 180+ class muley..standing perfectly still with an opening, but shooting a 300WM @ the time - wasn' t confident that the end point trajectory was doable with the window opening and range even with a perfect rest. One option on this last day buck might have been to pick the spot and " brush bust it through" ... beleive with the buck only 1' or less behind the bush, I' d have gotten him but did' t shoot. Waited for the clear shot that never came.

There have been other studies about deflection and some suggest that a target close - less than 6 ft from the deflection point has a good chance at getting hit... but I' m not willing to take that chance = rather use a scope and practice threading the needle so it' s a judgement call.

There was another study done suggesting that rate of twist and velocity has much more to do with " brush busting" capability than weight of round. Simply, a spiral thrown football is much harder to deflect it' s intended path than one trown with less spiral or outright tumble. Think of the bullet pass from a good quarterback deflected by a hand vs a tumbling thrown or kicked ball in the same situation.

So - maybe a rifle with a higher rate of twist on the barrel can deliver more reliability regarding " brush" - but again.. learn to " kill" the head of tablespoon in a hole at 100 yards and pick your most accurate load from my standpoint.

Also - much harder to stop deflect a faster moving object from going forward anyway... maybe why the 22.250 did well in the tests mensioned? Guess the same could be said about weight... tough to derail a freight train!
