Between the Pro Staff 3 x 9 x 40 BDC $149 vs the P Rimefire BDC $169. which is best for a CZ 455 Combo with the 22lr and 17HMR barrels.

The 3-9x40 Rimfire BDC 150 The BDC 150 reticle provides a 22 LR specific BDC reticle and a 50 yard parallax setting for confidence and precision out to 150 yards with a Rimfire. The pro staff 3-9x BDC is designed for long range the parallax setting starts at 100 yards.I would go with the Rimfire that is what I'm shooting on my CZ 455 22 mag the 17HMR is a necked down 22 mag which is faster and shoot flatter. With a 22lr /17hmr combo this 2 very different rifles when you change out the barrels I think the Rimfire scope will give you a quicker setup.

The pro model is just built to take more punishment, it's thicker and stronger than the basic one. If you are just in your back yard plinking the basic one will work just fine, but if you want to go hiking or put any significant strain on it, I would go for the professional version. It will last for years, I think the only con with it would be it being slightly heavier than the basic model.

I agree with other comments, the BDC is calculated for .223 not .270. The bullet weights are so different between the 2 calibers, (40 to 75 grains compared to 130 to 150 grains on a .270) you can expect from 2 to 5 inches difference in bullet drop at 500 yards. I would suggest a different scope as well, Prostaff is a great choice.

I like my Prostaff 4-12x40 rifle scope. The optics are very clear and I love the BDC. In my opinion it is a quality scope for the price.

I have two of these. One mounted on a S&W; M&P; 10 (.308) that I've swapped the flash suppressor out for a muzzle brake. Has 18" barrel. Normally shoot Sierra 168 grain HPBTs in hand loads. Last outing I was getting sub-moa results. Have the other mounted on Armalite AR-31 (.308) with 24" barrel. Have shot better than 1/2 moa with the same hand loads. I never worry about the BDC feature since that is pretty dependent on using specific factory ammo. I can wing it on longer shots pretty easily. Great scopes.

We'll Develin, Nikon doesn't make a bad optic product (Even though I use Canon glass for my camera). So no matter which one you choose, I'm sure you will be happy with your decision. As far as the BDC feature, I understand why you would question the wisdom of having it on a .22. My thinking is that not having BDC is not a deal breaker but having it for only $10 more is not a bad thing either. You probably won't use it a lot but having it might be an advantage from time to time. Good luck and good shooting.

I thought this was a waste of good money. I just received my rcbs # 235832 primer pocket swagger combo 2 for $34.99. I am waiting for my 308 brass or I could tell you more. This goes right in the press and looks like the answer I have been looking for. Hope this helps.

The pro has a 5" barrel. I have used this on a SW MP40 with the 4.25" barrel. After ~100K rounds I am ordering a new one. The laser is just starting to fail. The laser will not come on half the time (shaking it helps, but now what you want to do with a loaded weapon) The muzzle blast has actually deformed the ring around the light lens. I it is egg shaped with a flattened top. Even with this the light still works fine but it feels like it is harder to get the carbon off of the lens. I also have one on my rifle with about as many rounds on the light. It still functions as new. Just a few scratches. It does not have any exposure to muzzle blast though. The pro has a 5" barrel.

Not much difference, I like thumb hole to pistol grip. It is what ever your preference is. If you look closely you will see that the axiom is just a tad bit longer than the ibex. I am 6'4" and found out the ibex could be just a bit longer. No problem you can get extenders. So choose either one, both will be one of the best purchases you have made. Oh one more thing buy the bolt cutter broad heads. People get all caught up in Fps, just practice and shoot, and you are good. 280fps or 330 Fps, at 30 yards the animal is dead in just over one second. I have shot deer for 50 years with gun, bow, muzzle loader, and it is human error, not how fast or how powerful. Practice! Not much difference, I like thumb hole to pistol grip.

The only difference between the 2 is that the 938 has a 1/4" difference in barrel length and ambidextrous safety. Depending on how you wear it; either the barrel will stick out a tad bit (with the laser) or the handle will. Either way, as long as your pocket is deep enough, you or anyone else looking would never notice. If you are tight for money then I would hold out for one specifically made for it. It's due any time now. If you don't mind & can afford a temporary fix, until they make a specified p938 version, then go for it. I would.

I run it on a 24 in bull barrel and the Nikon website (http://spoton.nikonsportoptics.com/spoton/spoton.html#:4) I believe bases the ballistic coefficient on a 24 inch barrel and when I print up some of the bdc chart for my given ammo I'm shooting, it's pretty accurate. I was going to put it originally on my 18" barrel model and was reading that the bdc's would be pretty close. What was recommended was get the bdc print out, and then head to the range and you can see the slight differences on each circle and them you can adjust accordingly. I know that sounds like a pain, but the guy that was going over it, said that each bdc circle would be off say 5 or so yards so say if one would be 200, it would actually be 193 and so on. The bottom line is even with a 24 in barrel, I still confirm the bdc circles on each different round I fire down range. The scope is great and I just bought one for my father in law and he is hooked and a big fan. Hope that helps

You can download the nikon "spot on" app and check out how different loads match up using the BDC....its great and printable. I love that scope and utilizing the "spot on" app really helps better dial it in based on ammo using or if you ever decided to put it on a different rifle. But realistically depending on the ammo use its all about the fps as well as bullet weight and coeffocient, but download the app first and you will see what I mean. Enjoy

The main differences are Size and Noise Reduction. The Sport model has a noise reduction rating of 22db The PRO model has a Noise reduction rating of 30db Because of extra noise reduction provided by the PRO version, they have a much larger profile. The larger size COULD be in the way if your using them with a rifle, if you use a handgun, the size should not be an issue. In my personal opinion if the larger "bulk" is not an issue then go for the maximum protection you can get! Your hearing will thank you!

I bought both the M223 XR Mount and the 4-9 bdc 600 and installed them on my son-in-laws AR15.hey work great together. I also bought the P-22 and its respective mount and it also works great! All 4 were birthday presents for my son-in-law. We had a great day shooting both scopes in and we could not have been happier with the two combinations.

Like lost soul said, if you haven't bought anything yet, and just want to load 9mm and .223, you might be cheaper to buy 2 pro 1000's.

Really depends on your shooting style and preference. I have both versions, but i prefer the twist. Its faster for my setup. I have no problems with the quality of both versions, they work great.

Saw the previous answer which is correct, but save your learning curve time; go with GG&G; XDS-2 Tactical Bipod. Pricier but SOLID! Amazon sells both
