I hope so too!

Correct, it's the Grey Birch La Chassis with 16" fore end. This is the 2nd/latest generation which attaches the fore end by use of two screws rather than clamping on to a pic rail. The tolerance between the chassis and fore end is very snug which is a good thing. While it will not be as rigid as a solid aluminum chassis (i.e. PDC Custom, MDT, etc.) it is still rigid enough. There is some flex if you really put weight on it, but I haven't found it to be an issue and it has been just as accurate as other stocks/chassis that I have used. I've been happy with it. This is the same rifle that I took to nationals. The biggest advantage it gives me is the fact that the buttstock is very light which helps with getting the balance of the rifle forward of the mag well. Since I run the TriggerCam that puts a pound of weight off of the back of the scope which makes balancing difficult even with my heavy barrel. I have found this to be an easier chassis to balance than others. The folding stock also makes cleaning much easier. I plan on doing a review in the near future. I am also hoping to get a new MDT Premier Gen2 for the CZ 457 for testing as well. But with the Grey Birch being half the price, it's hard to beat for the money.

Yes, the NRL organization puts out the monthly COF and all matches run the same 5 stages. There are some differences, as if you read the COF, you will see that there are 2 options for each stage. It will be up to your local clubs Match director to pick option 1 or option 2 for each stage. They will tell you which option they are using so that you can prepare accordingly. Some clubs also run a bonus stage or 2 that is designed by the local club, but that does not count towards NRL league points, in addition to the official monthly COF.

@greghollis9006 ok thanks im trying to learn as much as I can before I go👍

@@bfox87 I would recommend going to a match first before you go to compete. It is still fun just to watch in person and you will learn a lot. Although if the closest 1 is an hour away then that might not be ideal. Just don't get discouraged after your first match. I know I didn't do great on my first outing, but then almost doubled my score from the first match on my second go round.

@greghollis9006 thanks, yeah I figured I'd probably have to just give it a go for the practice i used to race mx ive been last before lol but i eventually got a w. But I plan to somewhat replicate the cof at our local range for practice when I get my chassis back. Figured If I do that I'll atleast not be so bad it is embarrassing lol

Looks like my awesome viewers have already answered your question for me haha! Welcome to the channel and the sport! Each month I post strategy videos leading up to the first Sunday of that month going over each stage. As mentioned in other comments, yes, it is a published COF for the whole country/world for that month. You can find it at the NRL22 website (you may have to sign up to get access to the PDF). I have a video that shows what to expect at a match here: ua-cam.com/video/4K9E-o8TOm8/v-deo.html Most matches will be similar. I would recommend reading the safety rules multiple times and familiarize yourself with the procedures/commands before you go. I also encourage you to reach out to the match director after you sign up and let him/her know that you are a new competitor. In my experience, they will try to squad you with more seasoned shooters who should be more than willing to help. Don't be afraid to ask to borrow any gear that you don't have yet. It will help if you have good data on your ballistics, a bipod, and a support bag, but bags can be borrowed from other competitors. The main objectives are to stay safe and have fun. There is a learning curve, but you will quickly learn what skills you need to improve upon. Let me know how it goes and reach out with any questions you have.

The ISO chart that I intend to use will accomplish the same as the USAF 1951 chart. An official USAF chart is only 2 inches by 2 inches which is quite small and they are expensive if I want to get a real one. It is easy enough to replicate so I could add it to the other charts/targets that I plan on using. The brightness test is a good idea as many scopes dim as magnification increases. Thanks for the feedback.

Correct, Phoenix Rod and Gun Club. We'd love to see you at the range! I will be taking over as Match Director later this year so let me know if you have any questions.

Registration is open and I'm in squad 1 if you want to squad together

Right on man! I’ve been gone at work for 6 weeks. Hopefully home Thursday and I have to put my rifle together Friday hopefully and zero it and test some ammo Saturday I’m hoping. Hoping I can make it! Was holding off on registration til tomorrow to make sure everything works out with me getting home.

Currently using the Bushnell Match Pro (original version, not the new ED version), but I am in the process of testing some other "budget" scopes that will still meet the base class requirements. Stay tuned for reviews of those.

All scopes are different, but in general I'll parallax for the middle target and keep my magnification low to increase depth of field. Something in the 12x-16x range should allow for good depth of field while still being able to use the reticle hashmarks to make holds.

There is probably a way to measure that. Good suggestion. I will look into it.

Well, you're in luck because the first two scopes I will be reviewing are the OG Match Pro and a scope that I might replace it with that has 0.2 MIL hash marks. Stay tuned!

I definitely will be testing both of those

Thanks!

Absolutely. I will be using a geared head, the ballhead was just for demonstration.

Honey I Shrunk My Group Size!

Definitely something I want to test. Depth of Field is going to be very magnification dependent, but I'm sure the different optical configurations used by different scopes will lend to better or worse performance.

Great points. Most tests will be focused on the more real-world competition magnification ranges.

Grey Ops Bag Stop in the "shorty" configuration. Shorty is great for the CZ, but you may want the standard length for ACIS pattern mags like in the Vudoo or RimX

Great ideas! Mirage will be a challenge as it is more weather dependent, but depth of field/parallax is something that is definitely missing from most reviews.

Awesome, thank you! I'm trying to get a more objective evaluation of scope performance and I think I have some good ideas to test them.

Glad you think so!

Great point. I was definitely thinking of putting a color checker/color calibration chart out at distance.

It will take some time to get set up, but scope videos should be out next month! Stay tuned!

Great points. Seeing impacts on paper through the scope also makes zeroing much easier. I'll add that to the list!

I'll definitely give you a shout out. No one does the turret torture test like you do!

Thanks! For new competitors I always recommend dialing for each target, but learning holdovers will be important for getting higher scores. I just released a holdover practice target so be sure to check out that video. I'm running the Grey Birch chassis for the CZ 457

You're very welcome!

Hard to say. The first thing I might try is to change the position of where the buttstock meets your shoulder pocket. With the buttstock higher you're going to have less contact with your chest which might help with the heartbeat bounce. You may have to change or adjust your cheek weld and/or length of pull so that you can still see through the scope.

Agreed

Glad to hear it!

This match was at Phoenix Rod and Gun Club, but there are also matches at Ben Avery and Rio Salado Sportsman's Club.

@@CopperStarPrecision I wish I started competition when I was still in AZ

Nope. My logo is the state flag of Arizona so sounds like a fellow statesman is visiting.

Oh I’m an idiot. I was so excited. I was like babe he’s here. He’s from Arizona too 😂

Haha no worries, nice to know I have a fan club!

Thanks!

Happy to help!

Weight sorting is difficult with rimfire since you don't know if the source of the discrepancy is due to the case, projectile, powder, or priming compound so I don't bother. For competition I try to stick to the match grade ammo (Lapua Center-X, Midas+, SK Rifle Match, Eley Match, Eley Tenex) which has shown to have very consistent rim thickness across a box/brick/case. I do not yet sort by rim thickness, but might start doing so for my benchrest rifle, not my PRS/NRL22 rifles. Where I do see some potential (I am still testing and will release videos when I have conclusive findings) is to match the headspace to the rim thickness of the particular brand of ammo that you intend to use for competitions. Bolt shims decrease headspace and Barrel shims increase headspace. With my headspace of 43-43.5 thousandths it is well suited to the Lapua/SK brands. I see some marginal benefit to adding shims to get the headspace closer to 39-40 thousandths when using Eley ammo (still testing this out).

Thanks!

Short answer, no. Long answer, since all the shots are at 50 yards then no matter what velocity your ammo is at they should all be arriving at the target at around the same time. If you have a good 50 yard zero and decently consistent ammo the target will work as intended. For example, the 0.5 MIL hold, if you dial 0.5 MIL up from your zero and shoot the target, you would expect your impact to be 0.9 inches high from your aim point (50 yards = 1800 inches / 1000 = 1.8 inches x 0.5 MRAD = 0.9 inches). The center of the first (lowest) bullseye is set at 0.9 inches above the aim point. So keeping your 50 yard zero and holding over the 0.5 MIL should have the same effect and your impact should be somewhere in that first bullseye. What different velocity will impact is your ballistic solutions/DOPE for targets at different distances. So for a 100 yard target your hold or dial might be 1.8 MILS where mine might be 1.7 if we are using ammo with different velocities.

I just uploaded a MOA version on Patreon. Go check it out!

​@CopperStarPrecision got it thanks ill have to try this with my new setup 😀

Thanks! Don't forget to report back how you did!

Glad you like it! Don't forget to report back how you do!

@@CopperStarPrecision Went to the range today, got all setup to do this, and realized I forgot the details of how it was supposed to be done. Really good practice, but I didn't shoot it exactly right so I'll have to redo it later. I didn't hold quite enough wind, but all my shots were hitting high for some reason.

Hmm... it could be printed at the wrong scale. The document is designed to be printed actual size and the black bars should be exactly 1 inch wide. Otherwise, a strong right to left wind would push your bullet upwards (assuming a right-hand twist barrel).

@@CopperStarPrecision That's the issue. The black bars printed at 0.90".

@@KoryReeves try printing "actual size" or whatever setting ignores the printer margins.

Are you in ouray Colorado right now?

Nope

Thanks! Almost as awesome as your Eley Ultra video hahaha!

Paper never lies haha

You're welcome!

That's a great idea, I'll have to add it in the next version.
