    Out to 500m, a 40fps spread could mean max of 1.5" out = dead deer. Out to 800m, a 40fps spread could mean max of 4" out = wounded deer. Out to 1000m, a 40fps spread could mean max of 9" out =...

    grandpamac liked post by Bos On thread : Load Development - Velocity vs Accuracy
    Invitation wholeheartedly accepted Being what is considered "old school", I always test a load out to 400 and even as far out as 960 if I need to. So I know how the group is perfoming on paper which...

    Managed to bag a buck on Stewart Is. trip. The 168gn went straight through and would probably try a much lighter bullet next time. It was an unexpected 'long range' shot too at 350ish yards. ...

    It is a 22-250 1:12 twist Savage shortened to 21" and suppressed. I don't have access to a range so all my shooting is field shooting with a good rest but not a solid rest hence why I'm relatively...

    Hey grandpamac. I'd have to scope it to get a proper idea of what it's capable of. I fired off 20 rounds and managed about 1.25" at 50 after sighting in. This was at the range with very bright sun...

    To really understand "proof" you need to go to European sources, the USA has never had an independent proof system (some manufacturers operate their own versions of proofing) . I don't know if...

    264WM or RM are good examples where the cartridge/calibre is largely fallen out of favour these days, and has been for some considerable time. Hence load data with modern powders and let alone the...

    grandpamac liked post by Tentman On thread : The Importance of Using the Right Data
    Maybe but I often "analyse" loads posted on here with Q/L or GRT to try and get an approximation of the possible pressures they are running. Quite a few people are running loads that are probably...

    I was also going to make some comments. I load for a 358win using 308brass. With a 225 gr projectile I have a max load of 49 gr by book data for velocity in the 2450fps range. So when I look at...

    Just further echoing Grandpamac's views. I wouldn't trust any of the data in Harvey's book, unless you can corroborate it against modern reloading tables from the main players. As pointed out,...
