RE: "Tweaking" a load - Lumpy Grits - 06-28-2012
Please do so
You maybe surprised by the outcome.Try the c/filter paper too..
Have never used Steve's brew nor do I know anything about it, so I can't comment on it.
Maybe Steve will pop in and spill da'beans about it.
Wish I could help, I just have no trigger or loading time with the .40-65.

I would like to get 3 inch groups or better at 200 yards before I move to 300 yards, I am hanging around 4 inch right now
RE: "Tweaking" a load - Dave Roelle - 06-29-2012
I'm wondering if this might be a bullet/range-stability issue--------------I think i would shoot a few at 300 yards or farther and see if the expected increase in group size occures----------if so stability would not be a significant factor
I have one load in my 45/70 that kills turkeys but looks like a 3 minute load at 200 yards

I just finished getting my 300 +/- yard target set, I will send her 10 of the initial loads tomorrow afternoon.
my site setting for 200 yards is .38, what should I start with for 300yds, we are in the middle of a heat wave, no wind and when the shooting bench gets into the shade it will be 104 tomorrow
using Fed Mag primers did not show me anything, I will also try Win primers

Why don't you try pistol primers with a wad ?

RE: "Tweaking" a load - Kenny Wasserburger - 06-30-2012
Gary gave you some good tidbits to try.
I usually work up the load in 1 gr increases until I get good round groups. Once there I take it up .3 or down .3 grs till I find a happy spot in compression and the accuracy. In my smaller cases I use the Fed 150 Match Pistol primers with a wad of Filter Paper between primer and pocket to help headspace the primer and also for a primer wad. I start there as its a proven component. In the 2-7/8ths I use the old WLR's as I have a large supply of them and have proved to myself many times over they are one of the best primers for the 110, the fed LR Match also equal in performance.
I always anneal after every firing as is not only gives consistant neck tensions even though my PP loads have none, it gives consistant chamber seal and the Chronograph tells me that it works in single digit ES.
Something else most important, consistant grip and a firm one are a real boon to accuracy as these rifles torque a good bit. Kelley Roos has over the years made mention of that more then once it seems it gets lost in all the other chatter, Although I feel it is very important too. Having won a major bench rest bpcr match or two over the years, and losing by as little as .354 inches, I can not stress the importance of a good frim grip on the rifle. Rifles with a barrel foot are not nearly so effected by this (slug Guns) something to ponder on.

Hi Chaneylake:
I show a 19 minute difference from 200 to 300 for my 45-70------517 grain money bullet near 1300 fps at the muzzle.
Hope this helps get you on the paper
Dave
