Controlling muzzle jump at the bench.

This rifle has been the same but every once in a while it gets away from me and torques skyward at the shot landing 3" up and away.

check how the butt sits on the rear bag too, and how the rear drops away at the shot or rides straight back
I put the bag at the pistol grip /\

any input into the system has to be repeatable and consistent. Down pressure on foreend or scope is going to change poi, okay if its always the same

While I can't say I have tried that method but I understand the issue as squaring that away is something I am working on my self and that would be follow thru of the shot have a bipod you can preload I have had great success with in the past, btu ya its controlling the follow thru so the bullet can get out of the barrel before the jump or torque from position or trigger pull can affect the point of aim.

Follow through is critical to good shooting. About 40 years ago I met a guy at the Calgary gun show that was a competitive rimfire shooter and he said he practiced his follow through with a pellet gun with low velocity. The pellet spent more time in the bore than faster bullets and forced him to follow through to get Amy kind of accuracy. I developed follow through by shooting a flintlock with 44” barrel. Don’t know the velocity but it won’t be where most cartridges produce. From the time the sear trips to the time the ball leaves the muzzle is significantly longer than a hunting suppository gun. Either you learn to follow through or ##### and whine about flintlocks being inaccurate and difficult to shoot. As far as muzzle jump goes, I put my left hand under the buttock so don’t hold the gun down at all. I don’t get a lot of muzzle jump but I hold the rifle right into my shoulder which I think helps. The only calibres I think might be problematic would be Ruger no1 .338, high wall, 45-70, sharps 45-90, .45 whitworth and .500 BPE. None of those are problematic with muzzle jump BUT there are lot of cartridges that hit harder than those. Also, I like heavy rifles, they are easier to shoot well off hand, don’t recoil as hard and don’t muzzle jump. 6.5# .358?, I don’t know where the recoil of a .358 would compare to say a .338, but if it is more by much, muzzle jump off a bench could be significant I would think.
 
show of hands..
How many hunters sight their guns in on the bench using special gear and then go hunting without proving the zero from hunting positions or supports
 
Where there's an action, there's a reaction. A light rifle, heavy bullet, large caliber will result in more felt recoil and muzzle jump. Magna-porting will help tame the muzzle jump by a small margin, a muzzle brake will have a greater effect.

Moreover, the point of rest is on the forend of the rifle, be-it the front rest on the bench, free-hand, shooting sticks or bipod. When hunting, shooting an animal or on the bench, I do not hold the front of the scope, unnatural.................and I don't watch videos how to shoot or hunt.

AFAIK ... There is no one in Canada doing Magnaporting. I did have a 375magnum years ago that was ported and it did work very well for controlling muzzle jump.

I have not tried the method of applying downward pressure on the front ring so do not know 1st hand the expected results. I plan on trying it and comparing to what I have shot already. Have you tried it?

I had no reason to try it, I chose not to have such as rifle; a light rifle shooting a heavy bullet. BTW, what is AFAIK?

I think what you mean is... how many hunters practice from field positions. Mechanical zero is just that. The fact someone applies poor technique in the field to affect POI does not change the zero of the rifle. Changing the zero to account for something like sling pressure on the forend that may or not be there when the shot breaks on game is like chasing ghosts.
 
Interesting thread. I've never shot my lightweight rifles any different than I would my regular weight rifles. Most of the time when I'm shooting off a bench it's off a front sand bag only. I feel this simulates a hunting situation the best like shooting off my pack, the rail of my tree stand, a fence post, etc. I have never put any downward pressure on the front of any of them in any shooting situation.

I can see where this technique could be useful for load development and maybe I'll give it a try for the fun of it!
