Running out of time, but just needed to get er done anyway.
So, yesteday, had the alarm set so I could get to a friend's range in time to have the bench, bags, Chrony and targets set up in time to begin putting rounds down range by 6:00am. The friends are out of bed and having coffee by then.
My first in-depth 45/70 testing - 2010 - was with a 350gr LBT/WFN or LFN boolit that try though I might, I could just never get to give the consistancy or groups I desired.
That brought me, after more research to a Babore 465gr WFN mold and a lot more testing.
With the lighter boolit, I tested loads as fast as 2500fps, finally settling on the best of the lot at about 2300fps. As said just never got the results I desired.
I again tested a number of powders with the 465gr. with velocities mostly in the mid to high 1000 - 2000fps range.
Bruce's powder recommendation had been 47.5 gr (as I recall) of H355.
What do you know, not only did he make great molds - sorry he is no longer producing those molds - but he knew what he was talking about with powder and load.
I was also using a sample of his green lube.
Well on to the new tests ------- I wanted to test the proven boolit with some different lubes and retry some of the other powders.
So yesterday, it was H322, RL #7 and IMR4198 and White Label "BAC" lube.
No winners! HOWEVER, the powders may not have shown positive results, but that BAC lube left the barrel clean as I've ever seen it.
Other lubes always seemed to leave a touch of fouling in the last 1 or 2" of the barrel, but with the BAC the Barrel is left clean and bright end to end.
I thought that possibly I was over driving the lighter boolits, as the good results with the 465 were in the 1600 - 1700 fps range.
Thinking this might be the sweet spot for my rifle, Yesterdays tests were again in the 1600 - 1800fps range.
So, if the weather holds and the testing resumes in the morning (Friday) I will give the proven boolit a test with BAC and the proven load of H355 - 47.5gr. and see if there is a change between it and Bruce's green lube.
With a very early anterless elk season opening in just 6 days, Here's hoping I repeat last years events when I took what was apparently the first 2011 game animal taken in Ideeeeho, putting my huge cow on the ground at 7:10am, Aug 1.
An up date will follow if the up-coming tests provide any useful info.
Keep em coming!
