Ready to reload 230gr rn fmj's

[redactor]

Is 45 gr of Lil Gun still the 230gr FMJ load, or has that been deemed unsafe?

I've been shooting it for over a year now. Several hundred rounds with no ill effects.

I would disagree. No two chambers are the same.

I was seeing excessive pressure signs starting at 41gr and a 225gr FTX. Possibly, you could get away with that if you shot plated the bullets first with Tungsten Di Sulfide or Molybdenum Di Sulfide. The first being more slipperier than the second. You certainly don't want to start right off at 45. It might prove to be a short, catastrophic range visit. Work your way up from 40, in 1/2 grain steps, examining the case heads for imprinting and the diameter just above the web every round. I'm no old lady where load development goes, but trust me when I advise against that load without workup.

From the reloading forums, here are some threads that bear heavily on questions and points raised in this thread:

• anybody tried the magtech 230gr (.452)
  .
• 230gr fmj's-which brand?????
  .
• Cheaper bullet for shooting paper (This thread has some discussion of possible too-high pressures.)
  .
• These any good for plinking?

John,

Of course you're right. My question is.. did you work further up than 41gr. I'm finding something that might be going on with the new crop of primers and how they ignite the powder. With some powders, I will see pressure signs and then the signs, go away, as I work-up in charge weights. When graphing them on the computer, using strain gauges, those same loads will spike and then backs-off, as the powder charge increases. The high-end pressures return, with all the signs as before, but with much increased powder charges. Meaning, after the initial spike, the curve settles down into the normal range, to return at some later point. Go figure. I'm thinking some of these primers are causing the powders to react in ways, here-to-fore, not seen. The war has put production strains on all of our products and I'm thinking, the primers have taken a QA hit, but this hypothesis is not a fact yet, that is for me, anyways???

For you guys, this is not a license to just Willy-Nilly go for broke and increase your loads, this has got to be done methodically and carefully or the Pressure Gods are going to wreck your guns or worst..
