Definitely don’t want to zero with a magnetospeed!

Went out and load tested today at 300yards. Decided on the last group of 4 to test the speed. Threw on the magnetospeed for the first shot. Took it off for the next 3. Here is the target:

Guess which shot had the chrono attached?

you have just visually shown what suppressor shift looks like as well.

Not that bad, at least not for my 308, its less than 1/4 at 100. Some could be worse with a thin profile barrel. Suppressor that is.

Yep my rifles shoot around 5" high as well with the Ms attached.

Thx. Finalizing a load for the 28 nosler.

I shoot mostly heavy barrels and haven't found that much If any shift with or without The magneto speed attached. I normally use it for load development Looking for good SDs and ESs and if I find that one that looks good I will remove the magneto speed and shoot a group. Most Of the time there is no shift or group size improvement, But it is prudent to shoot the rifle as you hunt with it just in case.

I could see it making a difference in a lighter barrel even though the bayonet doesn't weight hardly anything so just to be sure remove it.

That surprises me also. A #5 barrel is fairly stiff and as long as it isn't over 26" long.it would be close but as said, It is always best to prove something as you did.

On my 28 nosler with a #4 Kreger I have seen the impact run from 6 to 8 inches high at 100 yards. I also have noticed the tighter I get the Magnetospeed the higher the impact.

 

[Blackdirt Cowboy]

My experience with it is 5" high and an inch or two left with the magnetospeed attached, mostly on sendero barrels.

On sporter contour barrels I find it not only shifts impact 2-5" high, it also messes with group size. I've taken a load that shot back to back 3/8-1/2" groups at 100 yards and put the Magnetospeed on and shot 3/4-1.5" groups. My Sendero contour barrels don't seem to group worse, but point of impact shifts.

My 28 is about a half inch high, several 338 RUM's same hole, my straight taper heavy 308 moves the most at a couple inches up. Barrel size doesn't seem to matter.
