Re: How to "Drive" a Semi-Auto?
Best way I can describe it is you need to be more consistant in everything you do with the AR. A bolt action has only one recoil pulse when fired. An AR has three. The first being the recoil pulse genreated by the bullet being propelled down the barrel. Same as any rifle. The secound is the mass of the BCG moving backward as the action unlocks. The bullet may still be in the bore as this happens, can't tell you for certain on that. Third recoil pulse is when the buffer spring pushes the BCG forward. The bullet has exited at that point. If you're holding the AR inconsistantly, that second recoil pulse that's not present in a bolt gun, may effect your accuracy, especially at longer ranges. AR's are a much taller platform than a bolt rifle. The balance is different and you may find yourself canting or torquing the rifle more during the shot and not realizing it. An AR has a swinging hammer vs a staightline firing pin of bolt gun. The ignition time of a model 700 is much faster than the AR's hammer. Might not be that much a problem shooting from a sand bagged rifle rest, but in the field, shooting from a less than perfect position, the extra tiny movement in the rifle as fires can make a difference. TRigger pull on an AR is much longer and heavier than you can get away with on a bolt gun. If you try to adjust an AR trigger the way you can a bolt gun, very light, minimal sear engagement, no over travel, and you have a full auto bumpfire session real fast. So because of all this, you need to concentrate more with the AR platform on being consistant with holding, trigger pull, follow through, pretty much all the fundamentals.
