Velocity Question

[ratrod54]

I'm sorry but I am not sure what forum to ask this question in.

I have been reloading for my 300WM for my hunting trip however I was not able to get a chrono on on my load. Can someone give me an idea based off of my specs? Is that possible? I just need to calculate my drops and while I know it wont be accurate, it will be closer than a complete guess.

73.4 Grains of RL22
Competition Technologies Partition Bullet
BC .507
180 grain
CCI 200 primer
Seated at 2.750 (doubt that matters)

I would appreciate any help.

77gr is listed at 3055 fps on their website with 180s, I would estimate 2875-2900, sounds like a light load but it could be very accurate. This is a estimation of course, far too many variables.

Do you have any confirmed dope for this round? Barrel length? Rifle manufacturer, stock barrel?

I haven't done much with this round. I had planned on taking another rifle but last minute things have made their way into my plans again so I had to work up a load for this rifle. It is on the light side but was accurate enough. I was ~.7 MOA. I did a ladder test and this was the third round I shot. I didn't have time to work up others and go back to the range so I am using what I have. Only dope I have is at 100 yards... I can hit my mark. Outside of that, I am guessing.

I knew this would be a long shot but figured it could be worth asking.
