G'day model 70, keepin well I hope!
Its is all about technique and I love the term Glenn Asher used “when I’m on”
I use to use a rcbs thrower but now use a Rcbs combi and my manual throwers are a Harrell and a redding br3 can’t use the br30 as it won’t throw enough powder on the larger cals.
I ain't no expert and don't claim to be but I have learn't a bit through trial and error, I found tequnique very important, consistency is the many thing, I don’t think it matters how you throw as long as it remains the same with every throw I will still use my manual thrower for most of my hunting rounds from 17 rem to 45-70 except for the long, long, long range stuff just to help with some sort of direction this is my routine,
I throw the first charge then put it back in the hopper then with the lever still down I will raise it to the top of the stroke (filling the charge) lower the handle about 1 cm (not dispensing any powder) then raise the handle hitting the top of the stroke (with a quick but light and consistent force) then repeat the 1cm top of stroke thing then drop the handle and cut the charge to dispense it, sounds a bit long winded but when you get the routine its quick and accurate a simple throw, raise the handle, tap, tap and throw again
Like I said it’s no magic technique but it lets me be consistent, hope it helps and gives you something to start with
P.S. The harrel is great but my old rcbs was a good unit to and able to throw neat charges.
lookin at some of the BR maniacs (in a good sense) they just throw on the day and vary their loads to suite (sounds so simple when you say it quick) but it comes with a lot of practice and experience, and they put ragged holes in paper and will shoot better than me in their sleep!!
If you are using flat out max loads weigh each load but remember speed isn’t everything and may not be the most accurate round for your rifle.
All the best
John
