Bought a 260 a while back, mainly for the wife to use. It is just a cheap Savage model 11 in left hand (both the wife and I are left handed) but a nice handling light little rifle to pack and has very minimal recoil. I don't expect match accuracy out of this gun, but I bought a couple boxes of Federal 140 match factory ammo and couple boxes Nosler factory ammo loaded with 120 ballistic tips when I got it because they didn't have any brass in the store and I wanted something to shoot right away. Both of those will shoot 3/4" groups and to the same point of aim at 100 yards. I did notice that about every third or fourth Nosler chambered stiffly which I am assuming is the brass, because they certainly aren't hitting the lands with those short 120s. Kind of surprised me because I assumed Nosler would be good quality brass.
Went to work up some loads today. I worked up several loads with 130 Swift Scirroco and H4350 (which everybody I read swears is the cat's meow for 260 or 6.5 CM) 41.5 and 42 grain loads were shooting 1.25" and 1.35" groups (3 shot) at 100 yards, respectively. When I went up from there the groups opened up over 2", but started to close back up above 43 gr. 43.8 gave me a 1.11" group but I had been seperating brass by brand (also have some Remington brass now) and the Federal brass was starting to show a little flattening of primers but no cratering at all, somehow I got a Nosler brass mixed in and that blew the primer plumb out. (Still no cratering, makes me wonder about the quality of Nosler brass which I've never used before. All brass is once fired and full length resized). With that result I really don't want to load that hot unless I do a lot of checking for pressure and stick with Federal brass. The groups just weren't justifying that. So then I loaded up a couple loads with 129 grain Hornady Interbonds. 42 and 42.5 grains of H4350, didn't even bother to walk out to the target and measure those groups, both looked about 3" through the scope. By then it was getting dark so I didn't do any more tonight. Another interesting thing was the Scirroco's were grouping 3-4" high compared to both factory loads, while the Interbonds seemed about evenly spaced around the bull.
Oh the Scirroco's were loaded to 2.80 OAL while the Interbonds were loaded to crimp in the cannelure groove. I don't have a gauge to check the distance to my lands but the Scirroco's at 2.85 I could feel touch them when I went to close the bolt a hairs breath, so I backed them off to 2.80 (my magazine will fit them nicely at 2.95 OAL).
Anybody else shoot one of these cheap Savage's or a similar rifle and can they tell me what they have had luck with for hunting loads? I really want to use the Scirroco's on game for performance but had heard they could be finicky to load. The Interbonds are also supposed to be a good big game bullet, but I have tried to load Hornady SST's in my 270 in the past and could never get good accuracy out of them (I also was supremely unimpressed with there performance both out of my rifle and several clients I have guided who used them, I would say 80% plus of them I have seen used shed their jacket and came apart, while I killed one elk with them and have seen some others killed with them I would never recommend them for elk after my experiences) so I wasn't totally shocked but was certainly hoping for better. I know the gun will shoot decent, just the two cheapest factory ammo's on the shelf both shot 3/4 MOA but I'm looking for a good hunting load, one the wife can use for whitetail, mule deer and possibly elk at moderate ranges, so I'm looking for accuracy with a quality bullet (preferably that won't break the bank). Anybody else shoot the Scirroco's and get decent accuracy? Is there another powder I should try?
