A: Thanks for reaching out Donna! I had no idea, so I sent your question to Hornady. Here is what they said: "I'm sorry but we do not have this specific data. However, as a general rule, you can expect an increase in velocity with a longer barrel. Since we know that rounds start out at 2910 fps out of a 20-inch barrel and you lose an average of 30-35 fps per inch of barrel loss, you can estimate that with a 24-inch barrel, you might see an increase in velocity due to the additional 4 inches of barrel length. This could potentially add approximately 50-100 fps to the velocity, but please note hat this is just an estimate and actual results can vary based on several factors including the specific ammunition lot, barrel tolerances, and chamber size."

A: The Hornady test data shows this to be from a 1.8" barrel, a very common length for small .22WMR handguns. The velocity is only 1000 fps from these short barrels. At this velocity, 100 FTLBS would be accurate
