No, that one shoots lights-out with anything 150-gr+

My Featherweight is the one I’m having the hardest time finding a load for. It doesn’t like 140s either. 150-gr. Nosler Partition Caution, load is max in my rifle. 48.5 gr. Rl 17 Winchester brass and WLR primer Velocity 2847 FPS. Note some of the velocity in the latest Speer and Nosler manuals leads me to believe the loads are OK. Loads were shot in my M70 Featherweight in 90 degree weather. Load were one inch or less, mostly less. Paul B. This is about where I want to be. I'm soon going to take a little different tack with this rifle. My plan is to use IMR4350 (just because I have quite a bit on hand) and run a Satterlee ladder test to find the velocity node, then start adjusting seating depth. I'll start with the NPT, but if that doesn't work I'll run through different 150gr-class bullets until I find something that suits my liking. Maybe being more scientific (i.e., Satterlee's method) will help. From what I understand, it'll sure save on time and components. It works excellent for me.

So I just purchased my first 7x57 (M70 SG Lightweight), and am pondering loads. My first inclination was to go 140’s since the load data suggests similar charges as the 7mm-08. I understand that the 7x57 has more case capacity and load data is light in respect to older rifles.
While doing some forum reading it seems most 7x57 guru’s prefer bullets in the 160-175 grain class. Is this because of nostalgia? or because most are built on a long action, so since there’s room, might as well use it? The rifle is the only opinion to follow. I have owned several 7x57's including a genuine John Rigby .275 and they were all different in preference but same in performance. My current Super Grade will clover leaf Barnes 145gn LRX's and shoots as low as .3's with 175gn Nosler Partitions. Everything else is ok for hunting but not the best loads for this rifle. There also comes a point in a handloaders life where the ability to maintain the accuracy potential of the rifle falls off so that also has to be/could be a consideration for the older blokes.
When truth is ignored, it does not change an untruth from remaining a lie.

GKs and NPTs about an inch, plus or minus. Oddly enough, it and my MRC absolutely love factory loaded 158-grain Prvi Grom. I haven't shot any of it over a chrono, but the box says it's about 2460 fps. If that's accurate it's pretty slow, but it gives one heck of a performance on game.

Who makes 175gr RNs now that Hornady got out of them? Good question, anyone? A quick check of MidwayUSA and Midsouth Shooters Supply didn't show any RNs in stock. Hardly definitive, but there you go. They both have Speer 175 gr Grand Slam Soft Points though. Perhaps not a bad option if they shoot well in your rifle. IMO, Speer offers a lot of bullet for the money across the spectrum of their product offerings.
