Bench-Talk

   Drawing from the wisdom on this board, i'm working with a redding br30 powder measure and it will consistenly throw incosistenly.  The range it seems to be in is .2grains for 20 throws so + or - .1 over or under target weight.  

  Question is: Is that good enough?  I understand that perfect would be better but has anybody done testing to see if +or- .1 is detremental to your score?

This would be for score shooting a 30br mostly at 100yds.

Main reason for the question is do I need stress need to scrap my br30 for something differant? 

   'Morning, Steve. You might want to try this and see if it improves the consistency: Instead of dropping a single charge, try dropping two half weight charges and see where the total weight ends up. I wouldn't be too quick to jump to a different powder measure in search of the 'magic' tenth-of-a-grain standard. But that's just my opinion...there's lots of ways that people approach this.  -Al

Im not the best shot in the world but can hold my own and it is my opinion after throwing and watching others throw that + or - a tenth of powder you will never see the difference. Hell I bet most cant see + or - 2 tenths if the wind is blowing. More errors are made with the wind and bench manners than in the reloading....just my 2 cents......Good luck

I'm with Leon. Flags cause more dropped points than powder charges variation.

I'm really not one who aspires to the double drop theory. Dick Wright is one who double drops. I feel if your charge is .2 off on one charge, if it's .2 off in the same direction, you are in worse shape than you could be in with a single drop. You guys think I'm nutty but I believe you have to practice and perfect your handling of the powder measure. On some cold long evening, sit there and drop and weigh a hundred charges or more. Then do it again tomorrow. I think you'll see some improvement.

  I don't know if the 'double clutch' method will be better or worse. That's why I suggested trying it to "...see where the total weight ends up". Might be better..might be worse..might be no change. But it might help identify the area that needs work.

  I'm a single tosser, myself. I'm not smart enough to double my workload.  ;) 

Stick with me kid, you'll, I'll guide you.

Okay, double click: If you want 30 grains dial to 60 grains and double click. Right?

Steve:

It also depends on the powder you are throwing. The longer stick powders are tougher to keep consistant than are the spherical ones. I don't see where the make of the thrower has much to do with this either. Just about all dispensers consist of a partial cylinder that rotated an adjustable opening in that cylinder under an opening in the body of the thrower. There is a cleaving action when the handle is brought down. Spherical powders part rather than cut the way stick powders do. We use Harrell measures and find we can stay within that +/- 0.1 grain window easily when using N130, 133, 135, and H4198, 322. It helps to choke down on the handle also. In our application for benchrest, the handle is longer than it needs to be.

   Thanks for the help guys, i'll continue to practice throwing.  Mainly using 322 and h4198
