AtownBcat I think I would still go for the 300WSM rather than the 300WM.

If I was going for a longer case I would go for the RUM, hand load and pick up the extra velocity.

You can make up a more lighter portable rifle in WSM but the RUM would be my pick for a heavy canon.

Re: Hey Guys Help the Newbie out!!!

If you want to know what difference velocity makes than punch in the numbers in a trajectory calculator like JMB JBM - Calculations - Trajectory

Re: Hey Guys Help the Newbie out!!!

BC = Ballistic coefficient = shows how arrow dynamic a bullet is.

Use the standard G1 drag (G is the drag equation used to make the model)

Velocity speaks for itself.

sight height is the distance from center bore line to center scope line (@1.5")

Zero height is the distance above or below your point of aim the bullet actually hits at the target (IE: 1.5" high at 100 yards if your sight in distance is 100 yards)

Sight offset (only if your scope is not directly above your bore like in the case of lever action side mounted scopes)

Windage and Elevation (leave at zero.. I never play with that one)

Line of sight (leave alone unless you intend to calculate for shooting at extreme angles up or down a mountain)

Cant angle (leave alone unless you tilt your rifle drastically lol)

Wind speed is the crosswind that you want on your print out. 10 is a good round number since it is directly correlated to the amount the bullet is deflected (20 mph will do twice what 10mph and 4 times what 5mph...)

Min and max is self explanitory

Zero range is the distance you shot at when you sighted in (here is where you actually need to use the Zero height) SO if you shot at 200 yards and hit 1 inch high than you enter 200 in the zero range and a "1.0" in the zero height. IF you hit low at 200 than you enter a "-1.0" in the zero height.

Input your relative humidity, altitude, and temp.

The last options relate to your scope adjusts in ... MOA, 1/4" clicks, Mils... Most American scopes are based on the inch per hundred rather than the MOA. Only your best Leupolds Nightforce S\$B... will be different.

Happy calculating!

Re: Hey Guys Help the Newbie out!!!

My opinion is to start w/ the 300rum. I think you can learn the long range game with any caliber. Some just go longer than others. You will have a quality rifle built, build it for the future.

Re: Hey Guys Help the Newbie out!!!

Thanks for the breakdown britz, the picture is starting to come into focus.

I called my local range and found out that the RUM factory ammo is about 15-20\$ higher than the WM stuff. I do want to begin hand loading as soon as i can afford the stuff.

Re: Hey Guys Help the Newbie out!!!

All you "need" to load is a balance scale, decent press, die set. Everything else enhances accuracy and makes life easier. I'm sure you could get a great start for under \$250
