[QUOTE="montana west, post: 1912086, member: 113504"] ok I have loaded ammo at 200'and at 5000 they shoot high about 2" at 100 m and the handloads are very hot up here... you need to drop your powder charges 1.5 grains so you will not have flattened primers.. from 200 to 6000 elevation.. I am sure that is why the 416 rigby is loaded at 40 000 cup instead of 50 000 cups because in africa it is high elevation.. I think that elevation has more effect than tempature.. another thing if it is light rain you velocity will go up as much as 75 fps.. [/QUOTE]
