I shoot 22 grains of IMR 4198 and a Lee 170 grain cast bullet. I think velocity is about 1800 fps. Can anyone tell me my trajectory at 50, 100 150 and 200 yards? I use this load in my 94 Winchester but I just got a Contender carbine with a 2-7 leopold scope, the generation one model. Any info appreciated. Thanks, Craig

You can also look for Hornady Ballistics Calculator on the internet (Hornady site). It's free and lets you put in all the details, and then does the calculations and gives you a printable table of results.

With your velocity being the pivotal variable, an investment in a chronograph at a minimal cost would be an asset to your tool kit. While working up loads for the 30 WCF and the 32 WSP, my expected velocity was very different from my actual velocity. My Chrony F1 which I have used since the early 90's, has been a valuable tool to determine my actual velocity. Once determined, accurate trajectory tables can be generated. No more guess work. The Chrony will also show you load consistency and identify the load(s) with low SD and Range.

Lee says the BC for that boolit is .268

Without knowing the exact velocity, all the calculators in the world wont do much good. I reloaded for years without a chrony, just went off what the book said. Now I have no idea how I reloaded without a chrony.

the tables will get you close, nothing for certain till you actually fire groups at the different ranges.

Or conversely to asking this question, you could just hang a target at 50, 100, 150, and 200 yards and find out empirically. Load charts, ballistics tables, and trajectory charts are only guidelines anyway. They can't possibly take into account the effects of temperature, humidity, elevation, and wind on your situation on any given day.

Kinda wish the forum had a "Like" button, then I would not have had to type in so many letters just to reiterate the above comment.
