it would be important to have knobs installed on your scope assuming yours dosent have them.
an elevation only knob would do but i would suggest you get both. the target knobs will have cover caps. the m1 knobs being larger will not. we could argue all day about which is better. i have both and they both work fine. i do like the caps however.
you could get by just fine with your duplex reticle and knobs.
that said dialing does take time and there is always the possibility of nervous error.
there are also other options beside the leupold reticles.
for example, t k lee in alabama will customize a reticle that is programmed specifically for your cartridge and load. www.scopedots.com
i have several scopes with custom multible dot reticles. they are very fast and accurate.
you can simply ignore them and dial if you like.
or you can fine tune with a few clicks.
i would suggest a 1 min. dot for your main aiming dot.
i would personaly not go smaller than 1/2 min on the others but certainly no smaller than 1/4 min.
