These are very good.  Use with my .338 AI

Some ballistic apps, Field Firing Solution, for example allow you to calculate accurate BC for your bullet from observed drop.

Are there any apps that account for lat / long and course of fire bearing?

 

I'm not aware of any that I’ve used over the years having this as a data input from the user

 

it may be that it’s automatically accounts for lat / long but one should be able to input the bearing / path / direction of fire to allow the logarithms to give a true solution 

 

Or am I wrong in that line if thinking (Matt asking you as your probably the most experience ballistician here )

Field Firing solutions software, http://www.lextalus.com,  uses these as the PDA has built in GPS for you position and you enter range and bearing to target.

Yes I take it into account, why would you not?

Ballistic calculators can do this so why would one not allow for it for long range stuff.  Yes wind is a more important factor but every little helps

Dyfed Powys firearms office have now confirm to me that  they will now confirm whether land has been cleared over the phone to certificate holders with a closed certificate.

To be honest I`ve yet to meet anyone from firearms admin whos experienced enough to determine if land is safe to use centrefire firearms on , what may get you a quick answer is if you can quote someone who is already cleared to shoot that land with centrefire .

You should get an open ticket after five years / on your first renewal , getting your DSC1 can speed things up.

I'm not asking for them to clear it.  I want to know if it has already been cleared

I would have through a phone call would have sorted that.

I was told today by Dyfed Powys that I have to send in a letter showing I have permission and a land clearance form.  I explained that I was not asking for it to be cleared only enquiring if it already was and for what calibre .  The lady said I need to send in the documents.  I have followed it up with an email asking it that is their policy as I would have though a simple phone call would save both them and myself time and resources.

How do you check with your local firearms department if land is cleared?

Can one simply phone and they check on their database or does one have to do it in writing?

I have my FAC now cleared for deer and AOLQ on land I have cleared and also on land cleared by the local chief police officer.  If i am invited to shoot on other land how do I check it out, at short noitice.
