crazyfrog Posted August 17, 2012 Report Share Posted August 17, 2012 I have a Remington 700 sps in .223 with 1 in 12 twist, I have the 4th Edition Vihtavuori Reloading manual and I have borrowed Edition 8 from a mate. I have brand new Lapua .223 Remington Match Cases. I also have N133 that I intend to use for this calibre, I have some N140 as well but intend using this for my .308 later on once I purchase one. My bullets are as follows: Sierra Gameking 55gr HP Boat Tail Hornaby 55gr V-Max 52gr BT A-Max 55gr FMJ-BT W/C 53gr HP Match I cannot find the specific makes and grains of bullets in either of these loading manuals, I would appreciate if anyone can either let me know the starting and maximum loads for any of these bullets or a link to any site where the data is available, I have had a look on the Vihtavuori website and they merely mirror the data I already have.... I know that the maximum bullet for the 1 in 12 twist is 65gr so I am well within ths with the bullets I have....... Many thanks Quote Link to comment Share on other sites More sharing options...
crazyfrog Posted August 17, 2012 Author Report Share Posted August 17, 2012 Further to this is the make of bullet critical or can I go on the weight on it's own,,,, Cheers Quote Link to comment Share on other sites More sharing options...
al4x Posted August 17, 2012 Report Share Posted August 17, 2012 weight of bullet gives you a perfect starting point Quote Link to comment Share on other sites More sharing options...
Redgum Posted August 17, 2012 Report Share Posted August 17, 2012 weight of bullet gives you a perfect starting point As above with maybe the exception of Barnes X heads, its amazing how the differant manuals will differ in start and max loads, I have always thought the Viht charts are on the high side but if you start at Min load and increase with care,keeping an eye out for pressure signs you should be ok. As always,its best to air on the side of caution and max loads are rarely the most accurate. Quote Link to comment Share on other sites More sharing options...
crazyfrog Posted August 17, 2012 Author Report Share Posted August 17, 2012 Thanks for that I had came to the same conclusion that I will start with a lower load from a bullet with the same weight and carefully work up... Cheers Quote Link to comment Share on other sites More sharing options...
