Youtube Magnetospeed mount...

I made one. Pretty cool. Now all I need to know is if the XFR works on an iPhone X

So where is the u tube video?

Where is the parts list?

Looks good

I thought it was common knowledge. Here it is https://youtu.be/ToQAHgDtJfM

Does it matter if your POI changes with the chrono attached? Why would you care if you are testing velocity?

I don’t think it matters one bit.

I recently used one to Chrono a Remington 700, just after I had sighted the scope in, and although it changed poi, down about 4” for those who care, it still turned in a sub 1” 5 shot group at 100y. Take it off, poi returns to normal, and now I know my velocity.

I think it would matter at distance. If you’re trying to confirm a long range load I’d imagine you wouldn’t want a 4 moa shift at 1000 yards.

My magnetospeed shifts poi upward .7mil. I adjust the poi using my turret. It only goes .6mil below the zero stop, so my poi is .1mil high with the chrono attached.

I remove the chrono after I’m done chronoing. I put the turret back on zero for distance shooting. I know this sounds like a lot of work, but it really isn’t if you’re normal.

In some situations, it saves ammo.

When the ladder test is done, you can zero the load at 100, then confirm groups on paper at say 300. You'd be able to do all that with the same 10-15 rounds that you were using to sample for velocity. The normal way would be to shoot rounds for velocity, shoot for zero and shoot groupings at distance.

Also, you can testing consistency of load velocity for different temps and altitude while shooting as normal. Same for seating depth effects on velocity whilst grouping. Test and shoot at the same time. A great option.

Lastly, its a money saving option. Magnetospeed has limited options for mounting the Sporter. This solves mount solves it.

Makes sense?

my finding as well when the magneto is on the barrel...always .5mils high but windage is in line with my zero.

The normal way would be to shoot rounds for velocity, shoot for zero and shoot groupings at distance.



Also, you can keep testing consistency of load velocity for different temps and altitude while shooting as normal. Same for seating depth effects on velocity whilst grouping. Test and shoot at the same time. A great option.

very well said...this taught me that when its hot and theres a lot of mirage its more the mirage that caused me to shoot high than the heat causing higher velocities...takes me all of 5 seconds to through the MS on.

you have something else going on like changing your posistion or your recoil control to get a 4" shift at 100 yards unless you removed a muzzle brake or something.

I've shot 100's of rounds over my Magnetospeed and never once on my precision rifle have i noticed a poi shift. I aim at a .5" dot on the target and if i'm not cutting the dot I'm within a bullet diameter of being on it with all my rounds stacking in one ragged hole. (.3-.6 MOA depending on how I feel that day) I do my testing I pull the magnetospeed off and shoot another dot on the target and the rounds impact within a bullet diameter or less of the new dot. And i can firmly state the any shift in impact is me and my failing to focus on recoil control. I'm guilty, I sometimes get in a hurry and forget a few of the basics, and I pay for it on target. But as soon as i do my job the with or without the magnetospeed attached the bullets go where they are aimed or they are within one bullet diameter of POA.

FYI my rifle is a Rem 700 5R Stainless .308 24" bbl, in a Manners T2A stock, Timney 510 trigger set to 2#, Running a Burris XTR 5-25x50mm Milrad FFP scope on a Talley 20 moa base in Warne rings sitting on a Elite Iron light bipod and supported at the rear with a Protektor Model leather bag. I shoot Nosler RDF's or Sierra SMK's 175 grain bullets in Peterson brass.
