i know huh...who posts more questions then me?? hope im not irritating anybody yet!
set up the new rcbs chronny today and let fly with some loads i been waiting for weather with and wowww why didnt i get one of these a looooong time ago?
first thing i found was the seemingly best load performance wise for my winchester hiwall...68gr 2f goex behind a 1/8th felt and compressed enough to seat the 457125 520 gr lyman to cover the greese grooves with the brass. this averaged for ten at 1090 fps with 11.5 variation with the 10 shots and shot like a business like rifle should.
this same load would shoot at 1112 fps average thru my ped sharps with its 34 inch barrel but the variation is 38 fps with the same loads.
my ruger shot 1052 with these loads but with a spread of 31 fps.
now after looking at the book i keep my info in it occured to me that with the longest barrel...34 inches...and the shortest barrel...20 inches...that the difference was only 60 fps velocity loss. im amazed with this small variation between velocity with a 14 inch barrel difference. i thought it would be over twice as much...what gives here?
another question is why the winchester hiwall gave such tight averages with fps spread of the 11... and the ruger and sharps were 31 and 38 fps spread respectivly....with the same 68gr load and weighed as well as assembled the exact same including the thrust of compression given on all loads.
still dont know about 1 or 2 or 3 hundred yd accuracy yet as i wanted to examine the consistancy of my loads first before exhausting the range with smoke before i am ready to test some loads with promise.
if these are any indications about the differences in velocity with regard to barrel length then its gonna be a no brainer about which rifle go with me into the brush this year.
another thing i noticed with regard to these rifles was recoil...meaning this...the ped sharps [even at 12 lbs] bucked harder then the winchester...and then the winchester believe it or not recoiled more then the ruger! after cleaning these rifles i did a very exact experiment with them.......i layed the sharps down and layed the winchester on top to inspect roughly the length of pull and drop at the butplate...then i examined the ruger on top of the winchester in the same fasion and this is what i see with my scientific examination.......the sharps dropped 1/2 inch more then the hiwall....the hiwall dropped around 1/2 inch more then the ruger!....[smilie=b:...WALLA! discovered why the recoil diferences between these rifles........thinkin about turnin the ruger into a 45/90 now.......so take that...:kidding:
ok so there ya have it...another learning day for teddybear!
answers anybody??
thanks for the patience with me...ill continue to charge ahead tho till ya get tired of answering these silly questions for me.
