The BD marks only mean something at a certain zoom, usually full. You also need to know your dope.

Their site has a link to the reticle that tells you everything you need to know…

Did it have a guide in the box? Those generally explain what each hold is calibrated for on a bdc reticle. Do you know what cartridge it's made for?

According to the description it is multi cartridge compatible.

Normally with a 2nd FP reticle with holdovers there is a chart showing what magnification you need to be set at for the drops to match up with your cartridge

There is, I linked it in my original post.

SFP is what a vast majority of the scopes are. Only thing to be cognizant of is reticle size changes with zoom, so dope for Christmas tree reticle needs to be noted at intended power use. I would just use 9 power for longer shots on that particular scope and get cozy with the subtensions of the reticle at that zoom level.

I have a 7mm Rem mag and when I find what ammo it likes best I'll stick with that and maybe just use a 300 yard zero it's going to be my Muel deer gun and longer shots are more common where I hunt

The reticle remains a consistent size regardless of power setting on SFP optics. The reticle size changes with zoom on FFP optics.

With SFP the reticle remains a consistent size relative to your eye, but not relative to the target, which is why magnification level is important if you're not using the center of the reticle. With FFP the reticle remains a consistent size relative to the target, but not relative to your eye.

Agreed, I said that assbackwards in my post. Subtensions of reticle change with zoom on sfp scope is what I was trying to convey. Goes to show you not to blindly trust some idiot on the internet and do your own research.

I've never been able to grasp the FFP and SFP thing. I get what they mean, just don't know ....? SFP is better for hunting game, and FFP is better for target shooting? I think? Or NO?

Blondes, brunettes or redheads. It's all about what you prefer.

Depends on the day and weather. Confusing, yeah.

Or, you don't get it either and are just funny guy?

I have my opinion, but ill start with reality... they both work, its a matter of personal preference for any application. whichever one gets, learn it and they both will do the same jobe equally. One is not better than the other in regards to hitting a target.

Now my opinion, from a hunting perspective.... FFP seems to be more popular because the militaries use it, and its way over rated for hunting. Its ideal if your going to both glass, range, and shoot your target all thru the scope, you dont have to move which is a tactical advantage.
Glassing game thru your riflescope is dangerous, unethical, impractical for long range glassing... and not what hunters really do anyways regardless of focal plane which is why the FFP tactical advantage is kinda moot for hunting.
Just my opinion.

Like others said above it's pers preference. I like SFP because the FFP scope I had was hard to see the crosshairs at all magnifications. Also I know my holdovers so I'm really comfortable with SFP. Maybe long range competitors do it differently but I always just use holdover dots/markings. Probably due to airgun shooting in the past where you get massive drop and massive wind drift. I kinda just use holdovers automatically once I learn a particular gun. I don't do any sort of really long range paper punching so maybe that's why I like SFP I dunno. SFP always seems to be cheaper also.

FYI here's a decent video on pros and cons of each:

I take it "Glassing" in this case is using the rifle scop instead of binoculars? BAD deal if you see some dude 150 yards away pointing a rifle at you?

So the consensus seems to be, personal preference, or how you learned from you dad! Now I've got a good grasp on the difference between the two.

THANKS! .
