[QUOTE="CA48, post: 2628992, member: 21446"] I’ve had some 75gr Hammer hunters for awhile now but just got around to testing them today. Pulled the 25sst out of the safe blew the dust off cleaned it up and mounted a scope back on then did a pressure test. 26” bbl 1&7” 90* CBTO 2.173 COAL 2.592” -.001 NT .002” Fed210 ADG 2X 75gr HH Bbl round count 1,301 Magneto speed H4350 58 3930 clean cold bore 59 3961 60 4074 ej mark 60.5 4091 ej mark sticky extraction Interestingly enough 60gr of h4350 is where I saw my first ej mark when testing the 90gr absolute hammers as well. But they were running 3796 fps, 278 fps slower. In short what inspired me to pull this back out and test lighter bullets is I have waged war with the coyotes! I’ve never been a cat guy, but in my area I have a lot of rats and rattle snakes. The snakes love to hang out on my porch in the mornings right by the door to so you get a nice wake up scare when you walk out the door in the mornings and the rats crap every where and chew wires up. Anyways I’ve started collecting barns cats and letting ppl drop off stray kittens. And now no more rats and snakes but the coyotes pick the younger cats off non stop. So I worked up a load in my fav truck gun, the tikka 243win 16” Bbl pushing moly’d 55gr Nosler ballistic tips at a mild 3,615fps. With a 100 yard zero it drops 6-7” at 300 yards and has been working great. But over time the coyotes have gotten smarter and I just have a lot of open country around me so it’s not uncommon for them to stay out past 300 yards and they never stay still long so ranging and getting back on them is very hard. So I started thinking I want something flatter shooting, in comes the 25sst. I’ve got a few rounds loaded up with 58gr/75hh That I’m going to test once the sun drops a little more this evening and if accuracy is ok il see what the drop is at 300 yards and how it compares. And I also want to see the drop of the 90gr AH’s to when I have more time. And then there’s this dream I have to keep ignoring where I build a 6SST running 55gr HH’s at 4600 fps just holding over on fur at 500 yards slaying coyotes by the pack! I have to say the wheels have been turning lately when it comes to flat shooting cartridges. [/QUOTE]
