Optimum Ballistics Techniques, Improved Edition 4
Posted: Mon Feb 01, 2021 7:06 pm
My latest improved version of OBT Edition 4 is now available.
Hi Everyone,
I have just finished an update on Optimum Ballistic Techniques to Edition 5. This is a major update of data and includes further refinement of the fine-tune technique, re-chambering recommendations and introduction of case life estimates. Nodal tunes in Sporter class have been updated to include the faster burning powders and particularly those with 100% burn in the 26 inch barrel.
The books are now heavier and attract the next class of postal rate. The price in Australia is now $55 including postage.
Anybody interested should contact me at g.mincham@bigpond.com.
Hope everyone is looking forward to some sanity this year and wish you all a happy 2022.
regards, Graham
