Yes I agree, the point I was making was that the velocity can be calculated reasonably accurately using a ballistics program if you dont have access to a chrono on the range. I was clear that the point of impact here is the important point, not MV. In my case as long as ME meets the minimum in law for the quarry then I dont care as long as I have a group zero (for want of a better phrase) for different bullet wts. Ron is trying to duplicate the factory round, something which I have done with my MAS 36 by loading in steps up to the max with the correct bullet wt and then achieving correct POI for the sight settings! Your point demonstrates what I said earlier about changing things on the rifle such as bipod, moderator etc which moves the POI. The BOSS system is ideal for finding sweet spots with factory and hand loaded ammo that will save you time experimenting with different powder wts etc with handloads. What I am trying to achieve is different to Ron, I need an acceptable poi for one rifle at different ranges with 2 different bullet wts. ron needs to tune his hand load so that he has the ammo available with one zero setting. I have done this for my mate and his 22-250. We are now at the point of ready to test the 2 preferred loads at 50, 100 & 150 for group and POI aganst his factory and prove which load we developed will replicate his factory. here factory sporting ammo is expensive and you cant guarantee batches so loading an identically performing round is a great help. He doesnt reload so I do it at my place in his presence so he knows he has the confidence to shoot that round!stubblejumper said:

The results are in...and they are better. I am on the mark at 100yds. 
Still a couple of inches low from the factory load but I am satisfied with this...for now.
(FYI - 45.2 grains of Re 15.) I will be boosting it in the future but right now I can't test anything new, just go with what I have. I don't know what the results are like at 200. (Too windy yesterday.)
Good point Stubblejumper. From the onset, my original loads didn't hit the paint at 200 which made me think that my velocity was not good at all. That's what's brought out all the guesswork regarding velocity. But your statement has hit home with me. Thanks.
The last thing is to see how they perform on deer on Monday.

Actually I no longer own a BOSS equpped rifle as I found that the disadvantages outweighed the advantage.I am able to produce accuracy just as good or better with load development as I could produce with the BOSS.I bought the BOSS equipped rifle out of curiosity after hearing so much about theBOSS system.
