with 4x in that type of quality glass there is ZERO reason to ever need higher magnification.
Maybe if you have 20/20.
zero
C'mon. Shooting at steel or at the center dot of a paper target?
the magnification is just one small factor. the quality of glass and objective size is far more important. honestly i've used crappy optics where couldn't see shit with 9x, even as close as 200 yards. then run a quality 3x optic and can see clearly out to 300+ yards. a good example is my leupold rimfire 4x optic running on the henry 22. that damn thing is so clear it's amazing. with 4x in that type of quality glass there is ZERO reason to ever need higher magnification.
OP- if your'e using a 4x magnified optic at 100 yards and not getting clear images, then the optic is either low quality glass or there's a refractive issue with the human eye.
another nice example: my nikon prostaff 308 with BDC. it's a 4-12x second focal plane scope. by all descriptions shoudl be high quality. it BLOWS. eye relief awful. glass quality shit. cannot see anything at 12x. it just magnifies all the imperfections in the glass. soon i should have it in the classifieds keep your eyes peeled

Best and worst groupings. 6,5 Grendel AR. 123 GR Hornady Custom Ammo.
Worse case 2.521 and Best at 1.686. That's a big group. What twist do you have on your Grendel and what barrel length. I know with my Radical arms 24' 1-9 I can group 1 MOA at 100 yards and My groups tend to tighten up at 200 yards and my groups are around 1.75. But this is also with bags and I tend to leave my scope set at 12x Out past 200 yards I crank it up too 18x But only so I can use the proper hold overs.
is your eye relief OK? (i.e., no black donut around the outside of the scope picture)
Yeah, Im not happy with the sizes of the groups. That's why Im starting with what were my first complaints (scope) and I assume the $15 trigger doesn't help. I have a 1:9 twist with a 24" (also Radical).

Eye relief was fine.
I have a factory trigger on my AR. Heavy but crisp. What hornady ammo were you using. I actually found the sst to group slightly better then the amax boat tail. Are you using bags? I can group much better with bags or a lead sled then I can with just my bipod. Bi pod only and my groups open up to maybe 1.25 at 100 and 2.25 at 200.
I was off of bags. I had better luck with the SST compared to the A-MAX.
Its not so much not getting clear images, I think the human eye had more to do with it. I know it has to do with more than magnification. Time of day was around 5-6PM, sun was setting and I was shooting directly into it. I was using a Burris Fullfield Tac 30. The center dot was too large (IMO) with the target bullseye. I was covering the bulls eye, but was relying too much on keeping the crosshairs in the scope level with the horizontal lines of my target and I think that is where I was loosing focus. (focusing between small black lines vs red bulls eye). It would have been nice to realize that the scope illuminates while I was at the range, and not right now.....
All I know is the entire time shooitng, I kept thinking "man, I wish I had a few more times magnification" LOL.
Hopefully I can make it to the range tomorrow to try a few different things to see if I can get some tighter groups. Swapping out my trigger right now. I may bring an extra scope with me to see if that helps me.
100 yard range. Shooting paper. I was using 4x today and was having trouble focusing on the target. But yet felt guilty at the same time. What do you normally use?
C'mon. Shooting at steel or at the center dot of a paper target?
good aperture sights allow some darn good accuracy....
Although Jasons should mention a few things.
service rifle and high power rifle is shot at known target sizes the black bull which contains X/10/9 and as far out as the 7 ring on the official targets. SR1 at 100 yards its a touch over 6" with the X being 1.35" at 600 its a 36" bull with a 6" X ring.
If your not familiar with " match sights" or the "match rifles" in NRA high power think long long sight radius and expensive aperture sights front and rear.
believe me im not that good and I shot better at 600 yards with iron sights my first time out than I did with my 400$ match barrel and 800$ scope the first time out at 600.
your vertical shot placement could be head position and breathing?
I don't ~just~ shoot highpower (or just match rifle for that matter.) Even for the up close "tactical" stuff I personally prefer a simple unmagnified red dot like an Aim Point. It sort of depends on what you're trying to do though I guess.
Other than jason, don't any of you guys use iron sights anymore?
