Does recoil begin before the bullet exits the muzzle?

[QUOTE="Golovkin, post: 1673248, member: 104797"] Thank you everyone! I really appreciate the thought, time, links and advice you all have shared. I'll watch the videos that Wiscgunner provided and make sure that my fundamentals are on track. About 15 yrs ago I read "the ultimate sniper" and I know much of that info has been forgotten and unpracticed. I'll try loading and unloading the bipod, vs. pack shooting, and see if I can get them to match, previously I've loaded the bipod heavily because it feels so stable, but I suspect that is causing the major difference in POI compared to off the pack. A few asked about groups, and that part is really consistent. Bench, bipod and pack are all about 1 moa, the pack might open up a bit more if the shooting position is tough. Cheek weld and parallax. This could certainly be contributing to the issue, I'm very conscious of the sight picture, but the stock isn't giving me a great weld and thats bothersome. The recoil is a big issue but I don't think we can attribute the POI shift to flinching because I can put 1 moa on the bullseye with a bipod, take the bipod off, shoot off my pack and have that same group but its just lower. It seems like I can see the muzzle rise happening in the sight picture with the bipod. I'll see what happens, but it seems likely I'll just have to forego the bipod if I can't get its zero to match my over the pack shots. And as others have said, a less violent rifle would alleviate much of this dilemma, so I'll pursue that after I've understood the cause more accurately. I'd rather practice my way out than buy my way out. Regarding the original question, assuming recoil begins when the bullet starts moving as many have suggested and seems plausible - what about the force of the bullet "pushing" the rifle forward due to barrel friction. Imagine pounding a bullet down the barrel with a rod and how much force one would need to apply, does this force cancel the rearward thrust, a little, mostly, completely? And, how would adding a brake help if the POI shift from recoil is happening before the bullet leaves and the gas hits the brake? Does the air in front of the bullet hit the brake hard enough to lessen in-barrel recoil? [/QUOTE]
