Testing Lapua Center X vs. SK Rifle Match 22lr ammo in RimX 

Don't worry, plenty more coming.

Don't worry, it's coming.

It's a RimX with a TT Diamond on it.

Thank you. It's the Leupold Mark5HD with the PR1 MOA reticle.

It's the AndiScan www.sqi-andix.com/shop/

Maybe cause your gun can't be tuned. There's something else going on with the gun if it can be repeated. When a gun is truly tuned there is no need to move the tuner ever again. We dont tune ammo we tune the gun amd find the killer ammo

Thank you. The TriggerCam requires some manual focus and it can be challenging. It helps to have a tablet hooked up so you can see better than a phone. Part of the problem is that there's no way to tell if it's focussed by looking through it.

I'm running a Leupold Mark5HD 5-25 FFP

@@FClassJohn OK thank you I’m thinking about trying one of the 10 mile Trijicon con 5 to 50 on a center fire just can’t make that choice between first and second since I’ve been using the second focal plane for 60 years

@@stephenkrampert3430 the biggest determining factor is whether you are going to be shooting known distances like a benchrest match or something more like an RL 22. Benchrest I would go for second focal plane and NRL you really need a first focal plane. In my particular case, since I shoot both, I opted for the first focal plane since it’s easier to shoot benchrest matches with a first focal plane, then to try to shoot an NRL match with a second focal plane.

So you shoot a second focal plane for your F class stuff? I’ll probably never shoot a match but I would like to go attend one and watch sometime are used to be a pretty competitive Trapshooter. It’s hard to mix both.

Thank you. So far my experience with the SK/Lapua has been that at it's core they have all shot about the same groups sizes for me. What's really changed as I've gone up or down the range of ammo is the quantity of flyers and how far from statistical center they are. I haven't shot LR Match yet but have some coming and will test when I get it.

Yes I think the standard plus will outshoot the match at one hundred or it does for me I can on a good day produce one quarter in groups with the standard plus hope this helps you. Beagleman

It’s an Ezell’s tuner. They clamp on so you don’t need a threaded barrel.

Sadly no, but I’ll be using it in my local league where we run a little looser. So you’ll get to see plenty of strings shot.

I've had good luck at bulletcentral(.)com

It's something I make. I'm going to do a video soon on how I make them.

Normally between brands I'd say yes but since these ammos are both made by Lapua they use the same lube so it's less of an issue if any from what I've seen. Much different than switching between Lapua and Eley.

No, I tested that and for what I do, I just didn’t see any relevant difference.

I use a Leupold Mark5 HD 5-25.

I'm not sure I know what you mean??

@@FClassJohn on the 50 yd. shots each brand of ammo was hitting to the left. Why not make a adjustment to the scope to hit the point of aim? I know you are just looking for groups. I guess I just like seeing the hole where the center dot is in the scope. Sorry for the post because you definitely know what your doing.

@@ronnydowdy7432 I totally understand what you’re saying and it’s not a problem. My Windy just constantly changing depending on when I shoot because of conditions so I don’t really bother centering it up too much during testing.

Most of the time sorting doesn't solve the problem. Sometimes you're lucky, a cheaper ammo batch can be cheaper and more accurate that another but it's not the rule. With low end ammo it can shoot tight, but flyers usually go further.

@@br4713 I did a weight sort of some Remington thunderbolt (it doesn't come much cheaper) and found a variance of +4 grains. I pulled the lightest and heaviest and weighed the separated components of each. The total weight variance was in the projectile, the powder charge and case weights were the same for both...

@@br4713 I agree with what you are saying. But I never said it would solve any problems. Sorting is something you can do when you can't get what shoots best. Sometimes sorting is just good for your mindset.😉

@@DadWil That's a pretty large variance of bullet weight. Probably that's why Thunderbolt is the cheap stuff. It uses the bullets that don't meet tighter specifications, where the ones that DO fit a tighter specification are saved for better ammo.

@@LoanwordEggcorn Yes it is and also why I could never shoot MOA groups with Rem Thunderbolts.

@@FClassJohn now I need to spend more money. Lol

I agree but I don't make the rules. Funny thing about ring sizes, they don't really matter in the end. All that matters is that everyone is shooting with the same scoring methodology. Whether 1, 2 or 3 minutes the same person will end up winning 99.9% of the time.

Yep, that's why I'm good with shooting the SK. I get good results for the price and I'm just in this for fun so it's a good balance for me. I've shot Midas and CX and of course it's better each step of the way but I'm totally comfortable with when I'm shooting right now.

It's this one www.sqi-andix.com/andiscan-micro-a2/

Honestly I'd rather not. I know they work for me, I know how I use them and the results I get and that's all that matters. If he doesn't like them or feel they work then that's cool too. It won't stop me from using them.

@@FClassJohn thanks buddy!

My cz457s will do the same thing. Beagleman

No not at all, and to be fair he's much better looking than I am...

Yep and that's why I tune at 100yds and it work very well for me. With rifle match, I'm shooting just over a minute at 200yds, a minute or less at 100yd now and all one big hole at 50. I would never tune at 50 unless that's all I was going to shoot.

This is also why it is more complicated than just taking any random barrel and slapping any random tuner on it. In order to have a barrel that will shoot well at 50 yards you have to design a profile that will naturally vibrate faster than you need it to for it to work well at 50 yards. Since you need it to move at 5.84 MOA/ms to shoot its best at 50 yards the barrel needs to be designed to naturally move faster than that. And then you need to pair it with a tuner that is capable of slowing it down into that neighbourhood. A tuner can't speed a barrel up. It can only slow it down. So the barrel on its own needs to be faster than you require. Then you can take a tuner that is designed to work well with that particular barrel and slow it down just enough to eliminate as much vertical as possible. And the specific target distance you will be using needs to be kept in mind when making those design choices. Can one tuner be moved enough to change one barrel's tune from 50 yards to 100 yards? If you're planning on shooting at 100 yards as well as 50 yards then you need to design the barrel such that it is too fast for 100 yards, and then design a tuner that will slow it down enough to work at 100 yards. Whether or not that same tuner is going to be able to slow it down even more so that it'll work at 50 yards is another matter entirely. It is possible that it could slow it down enough to also work at 50 yards when set for 50 yards. It is also possible that you would require a completely different tuner to slow it down enough for 50 yards. It will depend on how much adjustment the tuner has available, and how heavy the tuner is, how much of that mass is in the adjustment piece, and how that relates to the barrel and barrel profile. To repeat, it isn't as simple as taking any random barrel and slapping any random tuner on it. They have to accomplish certain things when taken together as a working unit. The length and profile of the barrel needs to vibrate too fast to start with, but only too fast by an amount that a complimentary tuner can slow it down by, slowing it just enough to be most helpful.

@@FClassJohn I edited the first comment to clarify, rather than leaving it at just one sentence. Hehe. The edited version and the reply I just left a second ago should help explain why tuning at 50 and shooting at 100, or tuning at 100 and shooting at 50, are both compromises that leave error on the table. For optimal results at both distances you need a separate tuner setting at each distance.
