I've loaded and shot the Speers but not at game so can't offer any opinions about them but can highly recommend R15 powder for the 375. I load only 300gr bullets and it seems to offer great performance without severe powder compression.

I have used them on game here in Alaska, and I second Ray's opinion. I would choose them over the nosler partitions, except for perhaps on the big brown bears.

Two years ago I shot about 200 of these - I originally wanted something what would shoot a bit flatter than 300grs (only had one rifle - and needed to do some springbok/gemsbok hunting in Namibia). Problem was that they wouldn't shoot hoot in my rifle - about 3" groups at 100m - and I tried all local powders & various primers etc. Ended up shooting barnes-x as I could get 1" with them. Positive side with the GS was that I easily got them up to 2800f/s (can't remember if it was S365 or S385) - so if the accuracy had been there they would have been great. But now they did a great job on tin-cans. Rgds., Peter
Sorry - I was talking crap. Checked my F/S conversion and I actually just broke 800m/s = 2622f/s - which gave pressure signs (primers slightly cratered) and I backed off to 790m/s which is 2585f/s. But still a lot better speed (but not accuracy) than I got with Barnes. Factory Sako 270grs Barnes clocked only 2513f/s out of my barrel but they were super-accurate and I ended up shooting springbok and gemsbok with them as I thought accuracy more important than bullet drop. As I knew I was going to shoot far anyway we sighted in the rifles at 250meters. Rgds.Peter
