    What scope magnification for 100 yards?

    Whats is the least magnification can you see 223 holes at 100 yards? Most of the time.

    Yes the most important part, how old are you?

    I have a 3-9 variable on my 223 Rem and I see the holes clearly at about 4x. If I use a very bright "splash" target I can sometimes see the "splash" without the scope (but, of course, I can't see the actual hole). I'm 70-- but the artificial lenses in my eyes are only a few years old.

    A lot depends on which way the range is facing, thickness of the backers and light mirage conditions for a given day. On a north facing range with good light and thinner backers I can usually see 224 holes at 300 yds with my 28 X 88 kowas. On a south facing range its iffy at 200 yds as the light dosnt get to the face to illuminate the bullet holes as well. The old canvas backers were great as they didn't seal up behind the bullets either. Corrogated card board backers can actually close up behind the bullet making them harder to see. Most spotting scopes in the 20X x 60mm range or larger should work for you. The bigger objectives seem to do better as they gather more light. I'm 54 and wear bifocals. I recently went to a pair of 25X x100mm binoculars on a tripod mount that are working very well for me and relieve a lot of eye strain and fatigue due to using both eyes together.

    Not sure what I can see .223 holes using a scope, but the scope I use is 40 power.

    I was thinking rifle scopes not spotting scope although a spotting scope might be the best option

    With mediocre glass I can see 22 shots in the white on 12x. With good glass I can see shots in the black on 12x. Mediocre is Weaver/Leupold. Good is Nightforce, US Optics, Marsh. I can see 22 holes in the white at 600 with the good stuff at 32x and up. A lot will depend on mirage and light conditions.

    My 40 power scope is a rifle scope!

    My spotting scope is 80 power!

    Using an old Weaver 4x on my Savage 110 rifle in .223 loaded with JHP bullets. I can`t see a bullet hole at 100 yds because the chipmunk has exploded!Robert

    No problem with 12X on regular black bull/beige paper NRA targets with good optics and bright daylight. I've got a Burris 6-18x50 on my M700 that stays set on 12X and last week I spotted for a buddy as he sighted in a new scope on his 22-250. BTW...I'm 72 and, after cataract surgery, test at 20-20 (corrected).

    March? Never heard if them and after looking them up cant afford one but a 10x ratio is pretty impressive

    I'll say this, I sure don't need a $2/3 thousand dollar scope to see .22 holes at 100 yards!

    Age over 60, eyesight correctable to 20/20 says the doctor but without legally blind
    12x binoculars in my gun bag will usually do it but if I have a long range gun with me
    then the 20+ to 32 power scope on the rifle will let me see it real good.

    Spotting scope (I have more than one) most clear is 90mm with changeable eye pieces
    and I can zoom into see the fuzz of the paper but then it was designed for astronomy
    so I would sort of expect that - I also have a 2.4 Ghz Camera system if I want to us that
    but usually use that for 600-1 mile target ranges.

    It isn't as much a matter of magnification as resolution. A high-quality 4x glass which resolves 40+ line-pairs on the USAF resolution test target will do better than a mediocre 10X glass capable of resolving only 30 line-pairs.

    The T series scopes weren't your average Weaver. I have three I wish I had more.

    I'm 64 now and find that I seem to need a minimum of about 9 power to shoot well at 100 yards. I have several fixed and variable target scopes in the 10 power to 15 power range. Most of them are decent quality scopes which definitely help. (Leupold, Unertl, Sightron, etc.) I use a 40 power spotting scope to have a better look at the target after I've finished shooting the group.
    I may have passed my "Best Before" date, but I haven't reached my "Expiry" date!
