Cali_Ed Posted March 8, 2015 Report Posted March 8, 2015 Ok guys every one has seen this picture from the other thread My question to you guys is should I call the testing quits or keep trying to develop each one of those load by adjusting seating depth? Or ♢don complicate poop with stupid poop?♢ mmy next goal is two test the 2 best ones at 300 and see what they do? What would be my next logical step?

IBefore you go out further I would at least chrony the loads to find out the velocity and deviation, as it may come into play, depending on how far out you plan to shoot. IMO
Cali_Ed Posted March 9, 2015 Author Report Posted March 9, 2015 Still need to get one of those lol. I think the range might rent them
survivalshop Posted March 9, 2015 Report Posted March 9, 2015 As you said , just shoot those loads at 300 & see what happens . The Velocity thing is over rated , but SD & ES will tell you more & you will see it at extended ranges . The COL will be max ( or close to it ) @ 2.800" , as you know its as close as the Magazine will let you get to setting the best COL & the bullet type may have an effect on the out come also
98Z5V Posted March 9, 2015 Report Posted March 9, 2015 On that 178 AMAX at 39.9 - didn't you have a very similar group size at a higher charge? Something at or over 44gr? That was one full pass through an accuracy node. The results at 39.9 and again at 44-something. You'd probably hit the one under somewhere around a 36gr charge. It's times like this - working all the way through an accuracy node - that you have to decide if the additional velocity will help you. At longer distances, it certainly will help. If you'll stay at 300~500 yards, then it won't matter.
Zebra644 Posted March 9, 2015 Report Posted March 9, 2015 Darb on the first pic on the left with the vertical stringing is the your cold bore shot that is to the right of the group or a called flyer? Still nice shooting
Cali_Ed Posted March 9, 2015 Author Report Posted March 9, 2015 I never cbs when testing, I always fire random ammo I have first.
Cali_Ed Posted March 9, 2015 Author Report Posted March 9, 2015 These where all my targets for that day .
Cali_Ed Posted March 9, 2015 Author Report Posted March 9, 2015 (edited) This is my previous amax load up, this was a rainy, windy day though Edited March 9, 2015 by Cali_Ed
edgecrusher Posted March 9, 2015 Report Posted March 9, 2015 The 39.9 looks good to me. As long as it doesn't op up at 300 beyond what it is expected to, I'd go with that and load up. Your groups will close with more practice too.
Cali_Ed Posted March 9, 2015 Author Report Posted March 9, 2015 As for the 175rmr would i be better of with the 42 or 44?
darb Posted March 9, 2015 Report Posted March 9, 2015 As for the 175rmr would i be better of with the 42 or 44? My vote: 44gr.
Cali_Ed Posted March 9, 2015 Author Report Posted March 9, 2015 (edited) 44 are on the far right Only thing I've noticed is the bottom rims aren't perfectly round? But that's the same slightly for the rest Edited March 9, 2015 by Cali_Ed
98Z5V Posted March 10, 2015 Report Posted March 10, 2015 (edited) Those ones on the far right are starting to flatten out - you're approaching a max there, with those. But, I'd shoot that if the accuracy was good. <thumbsup> Edited March 10, 2015 by 98Z5V
Cali_Ed Posted March 11, 2015 Author Report Posted March 11, 2015 I have about 40 made of the 44, after that I think I may go with the 42 just so the cases arnt getting super stressed out with a max load
