Can I get to 300 yards with this?

What is my max range that I can dial to?
-22lr Wolf MT- 1050fps, 40gr, BC=.130,
-scope rings= 20moa gain
-Scope=50moa adjustment range (which I guess means 25 in either direction)
-sighted in at 50 yards

Also, I would greatly appreciate it if you could tell me or direct me as to how I can calculate this for myself in future...Thanks!

The bullet will go 300 yards, but don't expect great accuracy. A BC of .13 and a MV of 1050 fps is roughly similar to a 9mm pistol round.

Mr. Smith,

I appreciate your taking the time to respond, but you didn't really answer my question. Let me be more clear. I'm trying to learn how to calculate and pre-determine the max range at which I will be able to dial to with the turrets on a tactical style scope.

Thanks

I didn't give an exact answer because it is the wrong tool for the job. However, here is the answer.

Step 1. Noting your current zero, dial your scope up until it stops. Note how many MOA up from your 50 yard zero you have until the knob stops. It should be approximately 25+20, let's say 45 +/- 5 MOA.

Step 2. On this ballistic chart, determine where you have 40-50 MOA drop:
Code:
Z 50yd  2000'DA
RANGE  ELEV-  moa    mil     | WIND(10) moa   mil   RANGE
  20    0"    0.70   0.2mil  |   0"   0.70   0.2mil   20
  40   -0"   -0.70  -0.2mil  |   1"   1.50   0.4mil   40
  60    1"    1.00   0.3mil  |   1"   2.25   0.7mil   60
  80    3"    3.70   1.1mil  |   2"   3.00   0.8mil   80
 100    7"    6.70   2.0mil  |   4"   3.50   1.1mil  100
 120   13"   10.25   3.0mil  |   5"   4.25   1.2mil  120
 140   20"   13.70   4.0mil  |   7"   5.00   1.4mil  140
 160   29"   17.50   5.1mil  |   9"   5.50   1.6mil  160
 180   41"   21.50   6.3mil  |  12"   6.25   1.8mil  180
 200   54"   25.50   7.5mil  |  14"   6.70   2.0mil  200
 220   69"   29.70   8.7mil  |  17"   7.50   2.2mil  220
 240   86"   34.25   9.9mil  |  20"   8.00   2.3mil  240
 260  105"   38.70  11.2mil  |  24"   8.70   2.5mil  260
 280  127"   43.25  12.6mil  |  27"   9.25   2.7mil  280
 300  151"   48.00  14.0mil  |  31"   9.70   2.9mil  300
 320  178"   53.00  15.4mil  |  35"  10.50   3.0mil  320
 340  207"   58.00  16.9mil  |  39"  11.00   3.2mil  340
 360  238"   63.25  18.4mil  |  44"  11.70   3.4mil  360
 380  273"   68.50  19.9mil  |  49"  12.25   3.6mil  380
 400  310"   74.00  21.5mil  |  54"  13.00   3.8mil  400
You didn't list your altitude and temperature or the sight over bore distance, so I used 2000' DA and 2.0" SOB. Your setup should be limited to somewhere between 265 and 310 yards without using additional reticle holdover.

You can use any ballistic calculator to generate the data above, or approximate it with a "9mm pistol round."

I plan to use this setup as a cheap way to practice fighting the elements(wind, gravity,etc.) and to simulate the long range shots that will be taken in the future with high powered rifles. I'm guessing that about 90% of the skills/technique used in long range hunting can be obtained through practicing with a near identical setup in a 22lr at shorter ranges. I realize that I will only get limited feedback from this rifle as far as my ability to shoot accurately. I also know that, at those ranges, that projectile pretty much becomes useless for any purpose other than making steel ring or perferating paper. I certainly dont plan on taking any animals at those ranges with this setup. Anyway...

Thanks for your time sir. I appreciate the follow up.
