Ruger 77 MK II probs

[Krag 1901]

I wandered out to check my J-Word bullet inventory the other day, and was surprised I had ~600 Hornady Amax 50's and ~200 Amax 55's on hand! Had me smiling for a whole day!

I'm also stocked up pretty good on ,308 bullets with 100, 110 and 125 grain bullets plus some 220 gr lead for the 30-40. About 15 lbs of a 170 gr loverian bullets along with 'some' Lee 155's, 165, and 190 gr hard cast.

Good news for once!

This last year has been one downer after another for me. Last Feb I found a cancer on my head and have been fighting the operations, radiation treatments and side effects all year. Finally starting to feel better.

Ground hog says six more weeks of winter so, hopefully I'll get my loading bench cleared off and reorganized to burn up the powder and bullets on hand, when It warms up this spring.

Found some more data on 2015 and RL10X in my Hornaday (2007) reloading book, both for .223 and .308W. Looks like RL10x might be a bit slower than AA2015BR. Only a couple of grains different from 4198.

For 223 I have used IMR 4198 since the 223 first came out. Now that there a lot of newer powders for the 223, I will probably try some other powders even though 4198 works very well.

I've used a lot of 4198 in my cast loads but used 748 in .223 cause it worked good. Couldn't find 748 so bought the 2015 and RL10x as substitutes. Now I have to use it cause too cheap to not.

I was able to recover some of my loading notes that I thought I had lost forever! When I was shooting every week once or twice, I took digital pix of my groups and recorded my notes in a word .doc by caliber, with the results of the Chrony and my observations on my own capabilities behind the trigger. A few years ago my Windose Computer "blew UP!" and I thought I Iost every thing! It did not help that aI lost my range note book about the same time.
When I had lost everything in such a weird manner I switched to Linux and have been happy, except for the loss of years of data.

Yesterday I found a forgotten back up file I had saved and lo and behold I had done some things I had forgotten I did in my last year of shooting the Krag and .308. Some of which was directly applicable to my musing during the Covid range shut down.

For-instance I had tested some H 322, AA2015, and RL10x loads in the .308 that proved these powders were capable of use in Cast bullet loads at lower levels than are listed in any manual I can find, and at velocities up to 2,200 fps. With 4198 and 2400 I had never remembered going over ~1,800 fps with much accuracy. I also found I had pushed 2400 and 4198 a little higher and found a place where 4198 had 'gotten on the step' and produced velocities over 2,000 fps in the .308 and Krag.

My .223 file did not show any use of AA2015 or RL10x, strictly 748 with satisfactory results. So I'll test those in the .223 now that I have lots of .223 bullets and SRPs.

Maybe 2021 will be a year where the 2020 will be just a bad memory?

Searching for data on 2015 and RL10x has gotten me a lot of pdf files, including a Lyman Cast Handbook and a Lee #2 manual, as well as several .308 specific data books. It is odd though that the Lee manual has very few, to none, cast loads for 30-40 or .308, though a lot on 30-06?

I still cannot find much on RL10x except the the mfgs MAX jacketed loads.
