If the brass from 5.0 grains of you favorite powder hits your hat & glasses most of the time, and 5.7 bounces off a 10 foot high ceiling what charge would you try next?

5.3, 5.4 or other?

Thinking that at least BTF is stronger than FTE or DOW.(dribbling over wrist)

Maybe 5.3?

Why not just load a few of each? Just step through the entire range until you get what you want.

What is your goal?

Make quick work out of it and take your press to the range.

What I normally do is print out a bunch of targets and load up 10 rounds with every other 10th of a grain. So if I was you I would load 10 each of 5.2, 5.4, 5.6.

Personally I load for accurate loads. I don't really care were the brass goes.

I'd check my revolver, I think you have a problem.

It's called load development or working up your loads. A proper, at least IMO, process is loading 10 @ starting & then working up in 1/10gr increments to max, never exceed max data. Fire them in order, note functioning, accuracy, recoil, pressure signs. Your best load will show up.

Sounds like a winner!

But I figure the gun is a lot more accurate than I am, though, so accuracy of my rounds is not an issue yet.

Still it's amazing how soft that G38 shot with 5.0 grains of PP. It FELT like a .22 Magnum!

OK, thanks SCM. For the newbs that have missed it:

BTF - Brass to the Face
FTE ` Failure to Extract (Eject)

This might be good reading for those wondering about all the acronyms:

I don't think I like a pistol that throws brass in my face, no matter what the load, but then I guess I am picky.

That's pretty slick the way that you devised the press stand to fit into the hitch reciever!!!! Really like it.

You're one smart, inovative and imaginative person

Please don't use obscure acronyms. Lots of people around here are old and not will informed in the ways of digital media .

C'mon, country... they put the sights on top for a reason.

Made 50 rounds with 230 gn roundnose tmj (plated) over 5.3 gn PP and another batch with 5.5 gn. Will shoot them at IDPA tomorrow. Mainly looking for decent ejection. Accuracy should be good enough for marksman class.

I had some of my original HP my LGS guy helped me build, which got stuck in the mag. (These were the ones using a "scoop" (.5 cc) :wow: of HS6, and when I measured the OAL, it came out longer than 1.080, and the point of the HP was rubbing on the front of the magazine. I reseated those and plan to use them up.

I also have a box of factory loaded 230 gn roundnose, I won't even have to touch.

So I'm all set for IDPA practice tomorrow. This will be my first practice classifier with the G38. Gotta do better than with the G27, right? We'll see.

"The G# Framework is an add-on toolkit for LabVIEW (http://en.wikipedia.org/wiki/LabVIEW) that adds reference based object-oriented support."

I'm not entirely certain how to apply this to reloading. :rofl:

Well, if I'm gonna tune my extractor, I'd rather it be sharp than flat, and it just has to be in the key of Glock.

How else would you tune an extractor? :tongueout:

Sometimes checking Wikipedia can get you ALL messed up! Was that article in English?

Well, in spite of extractor being a bit out of tune, the GAP shot nicely last night - with a couple minor exceptions, all my fault. Ol' cheapskate had to go and re-use damaged bullets, like when I'd neglected to re-flare rounds I'd pulled and shaved a slice off the side of the bullet next time I seated it in that shell.

So diameter ended up too big, and pistol Failed to go into Battery when loading those bad rounds. I got pretty adept at malfunction drills. I think I ended up with 5 bad bullets out of the 100 I'd built.

Every one of those malfunctions ended up with a very "teachable moment".

Never fear, my reloads will be better NEXT WEEK, and I WILL NOT be using them for SD carry!
