Finally got my 300 Win Mag back, I sent it off to fix the feeding issues with the push feed, it was built for me about 5 years ago, had been single feeding it to develop loads until last year when I used it for a double nilgai hunt last year and noticed the feeding issues. It's a Remington 700 Sendero chambered for 7 STW that I bought in the mid 90's. After burning 3 barrels, I converted it to 300 WM with a stock change to a McMillian fitted with a ATACR MOAR 5-25 F1, I just found out its a F1 after all these years, it was mostly untouched in the back of the safe, I have always been a 2nd focal plane user and I don't regret buying the F1. Had the feeding issue solved with some adjustments that he should have done when he built that gun, rounds kept popping out when I would chamber to load the first round and 2nd round when I was hunting nilgai and it was not a good thing to have so I had to rely only on one shot and it worked. I had a wrap around cheek pad with foam inserts and never liked it, so he installed a Kydex cheekriser and I like it.
I had remembered when I last checked the bore with a bore scope last year, I am going to work up some loads and ran a bore scope through the barrel again to check the bore and I saw some firecracking in the throat, but not severe so I guess it has some life left.
Going to use some of the RL 25 that I had used eons ago, I got a little less than a pound, and I have always used RL22, and I have one pound left but I don't want to use it, I rather save it for future use. Saving a pound of RL 26 as well.
Has anyone used RL 25 for the 300 Win Mag? I don't see this powder on the Nosler site, but I see it on other sites. I plan to use it with 180 Ballistic Tips and Accubonds. Hodgdon is a tad slower but H1000 is a great powder that I am thinking to use as well and more stable than RL 25. Going to do a 3 round ladder with RL-25 in .5 increments from 78.5 to 80 grains as a start at .020" off and see what it shows on paper.
Edited to add: Just checked Quickload, it shows 107% fill with only 78.7 grains at 59157 psi at 3127 fps. I was hoping to push close to 64k psi. I guess one way to find out. I don't like powder crunch.
