Magnetospeed tightens groups ???

[Piney]

I've had good results with the limb saver tuners on both my Ruger ranch rifles. Shrunk groups in half on one. The semi autos with metal contacting a thin barrel & the working action itself introduce a lot of vibration & in my mind benefit the most...haven't tried them on the bolt guns I own.

I bought both sizes of Limb Saver tuners so now that I've concluded load development for velocity and relative accuracy, I'll try with & without the donut. I've noticed that Jim Shockey seems to have one on some of the rifles he hunts with.

I did not want to say this because thought everyone would call BS on me but.... My 280ai also shot pretty darn well with the Magnetospeed attached. The Poi shifted to a similar spot as my x47L. This was also with different loads. Perhaps a weight on the end of Sporter barrels can have a positive impact in some instances. These are full custom hunting rifles done by Borden and Beanland. They can shoot pretty well on their own. I am not drawing conclusions, just asking questions about an unexpected result. One of those "blobs" might be fun to try.

Every sporter/hunter or call the medium barrel profile rifle I own shot better with a Suppressor on the end, it might/probably is a couple factors that contributes to this but the little extra weight on the front definitely helped me. My one rifle went form a little better than avg shooter to the most accurate rifle I own but that rifles groups goes for a ball as soon as I try to attach the Magneto onto the suppressor to shoot with, the extra weight of the Magneto with the suppressor attached is probably just to much and then changes everything again.

Here's how it works: Changing the barrel contour, length, or adding weights to a barrel will change the frequency with which the barrel vibrates. (Length has a HUGE impact here, but nobody ever seems to talk about that). When you change the frequency, you change the manner in which the rifle whips when you fire it, which changes the bullet impact point, and possibly the group size. This is how tuners work. You are monkeying around with the barrel's resonant frequency. If you get it just right, you get better accuracy. If you get it exactly wrong, you get worse accuracy.

You have to try it and see what works best.

Adding a weight (and length, sort of) to a barrel with a magnetospeed is not too different than adding a tuner. It's going to change things unless you come up with a way of isolating the barrel from the magnetospeed, which is easier said than done.

Now I am super curious. I am going to buy one of the cheap Limbsaver rubber barrel things. I think they are 10 dollars. Will cost much more than that to test it out. I run in low class shooting circles so it will not be embarrassing to be seen with this goofy thing on my barrel. My buddies will think it is cool looking.

Cut some groves in it and call it 'tactical'

Might be able to install a rail on the barrel and then mount it to the rail. That would be highly "tactical"

Magpul.....are you following this?? If so, CTK expects royalties.

The fact that a mass on the end of the Barrel can help or hurt accuracy is why tuners are adjustable. Tuners work and if used properly, are not random at all. Rather, they are very consistent and repeatable in what they can do.---Mike Ezell

I'm so glad I found this. I recently built a 16" 6.5x47. The 130vlds shot amazing with my suppressor. Load was verified. Fast forward 2 weeks. I started load development with the 123gr vmax. Found my sweet spot and went back to the range to verify. Both my 130vld and 123amax loads shot horrible. I was stumped until now. The only variable was the magneto. I also experienced poi shift

I use magnets and tape but have never really really done the experiment use the big square 1x1x2 magnets,the magnet is incassed in steel gonna try it out next week, I don't have a crono so I just plink

I am now the proud owner of an 11 dollar Limbsaver X Mark Barrel Deresonator Delux. Bought it at Bass Pro Shops last night. I was anticipating having to choose between desert or leaf camouflage patterns. Thankfully it was available in black. I may give it a try this weekend. It is definitely not as heavy as the Magnetospeed bayonet and therefore may not reproduce the magical group I shot last weekend with the Magnetospeed. In all seriousness, this will at least be another lesson in my shooting education. I watched a YouTube video from some guy in GB who's point was that barrel tuners are for people who shoot factory loads. He stated that handloaders have the ability to "tune" their loads with powder and depth changes. There is obviously truth in that statement but am not sure if the perfect load were found, that it could not be further improved by the positioning of a tuner. I am well aware that the tuner could open up the perfect load. Playing with this stuff is simply a way to keep shooting and supporting our reloading compontent manufacturers with sales and gunsmithing community with rebarrel jobs

IME, tuners won't improve your best groups from your perfectly tuned rifle/load combo. BUT, what they will do is to widen the tuning node, making it stay in perfect tune longer, make finding tune easier, and give the ability to maintain a higher state of tune throughout any condition changes that would otherwise take it out of tune. IOW, they will improve agging ability but will not improve upon a perfectly tuned rifle, tuned by traditional methods. Comparing your best groups without a tuner to your best groups with one is setting yourself up for disappointment. Comparing your worst groups with and without a tuner would be a better way to judge a tuner's benefits, but the overall agging ability is the true benefit of them. They work and are stupid simple to make work! I simply use a good load in the rifle that I can trust to never be too hot and maintain tune with the tuner. This allows for going anywhere, pre-loaded and simply moving the tuner to achieve and/or maintain tune in whatever condition I have to shoot in.

This thread points out the obvious benefit of having a mass at the end of a barrel but implies that large jumps in weight or change are what it takes. This is far from the case. For example...my tuners have 32 marks and are threaded 32 TPI. This equates to basically .001" of tuner travel per mark. It's very typical for 4 marks to be the distance between completely in and completely out of tune. So, .004" of tuner travel to take it from in to out of tune. AMAZING isn't it? The single biggest and most common mistake made with tuners is assuming that larger adjustments are needed. All that's needed is to be very methodical and DON'T make big tuner adjustments that leave you randomly hitting or missing sweet spots. Simply hanging a nominal amount of weight(magnetospeed) from the muzzle will yield random results, as we've seen in this thread. Randomly moving a tuner by some nominal amount will yield the same result.

As a whole, the only people that don't like tuners are those that don't have one and those that use them incorrectly. They have proven to work and the time is fast approaching where you either use a tuner or get beat by someone that does.--Mike Ezell
