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
