    Yep read that thread also, actually purchased a new sierra 11 manual to cross fereference the current sierra app. Most loads are a grain or more over what the powder manufactuers recommend. Going to work up a defensive 38 +p load soon also to have in the data bank.

    I reload for accuracy, which usually does not translate to fastest. If my SD bullets don’t expand properly at the accuracy speed, I find one that does.

    YMMV

    definitely could not agree more, Luckily most of the loads I have used have been common loads used by many so there is a ton of data on how well they work online. I for example worked up to a max load of trail boss in .38 special and 357 magnum and found that instead of max 4gr shot more accurate.

    for some reason also I find that in .38 special plated ammo shoots better when loaded to +p and soft lead shoots better at +p loads. I find that if I match the bh of the bullet and the psi so it obturates correctly int the barrels it greatly increases my accuracy. could be attributed to most of the lead bullets I use have a bh of 10-12.

    speed is useless If I cant hit the target lol

    Appreciate the input from everyone Thank you all

    It's an old thread, but a current topic because people always wonder about the "hot" loads of yesteryear. You mentioned Lyman's 44th. Here is the data for 240-250 grain hard cast .44 Special back in 1967, tested in s Colt SAA. Loads like this give people the heebie jeebies today. Just for informational purposes.

    One thing to remember about manuals and their data... Test barrels are just that. Unless you are shooting with the exact same gun/barrel your results will vary. Find the load YOUR gun "likes" and stop before blowing it, and you, up.

    to me its a lot like following as gasoline recommendations for your new 2019 car by using recommendations from a 1953 manual.
    things change over time, especially years and years.
    first no 2 batches of any powder are identical, the chemist guys at the powder companies add stuff to get the powder rates as close to uniform as possible but still.
    a powder that was manufactured say 30 -40 years ago is not going to be same as a powder manufactured last year typically. add to that that these load rates are generalizations as to performance with a mind on safety.
    as we are now a much more sue everybody nation well safety margins have been increased, guess someone is trying to protect us from ourselves???--well I will show them-- here hold my Beer!
    in the end does it really matter that much if your load produces 550 Ft pounds of energy or a measilly 530 Ft Lbs of energy???
    we all have our loading rituals , myself I will stay within the recommended loads from the current info.

    I use current load data for all but one of my loads, that one I don't is .32 S&W Long. I am using data that dates back to the early 50's I think. Well above today's max data. I worked up to it slowly and watched for signs of pressure that never came. What I did do is get my cases to expand properly and not get scorching down the case almost to the rim. I also started getting complete powder burns, which never happened with current data. Now my .32 S&W Longs are hot loads in modern terms and they are also way more accurate. I did work up my loads in a .32 Mag revolver to stay on the safer side.
