I just put a 22 creed together. It's a savage 10 action with a 28in. 1in 7 McGowan barrel. I have just over 100 rounds through it now. I tried h1000 and h4350 in it. I ran 75 & 80gr eld-m, 80.5 bergers, 77gr TMK's and 77gr nosler CC's. 4350 ran almost 500fps faster than h1000 with same charge. I ran 4350 from 40-44.5grs and H1000 from 40-46grs. Most groups were at the .75moa mark. A couple bigger a couple smaller. The load I stuck with was 44gr of H4350 with a 77gr TMK. 5 shot avg was 3636fps at a .490 group. Zeroed at 250 its a 10in drop at 400yds. I took 2 antelope last week with this rifle and load. Doe was at 390yds. Buck was at 475yds. Doe was a shoulder shot and crumbled instantly. Bullet jacket was under hide on opposite shoulder. Buck was heart shot with pass through. He took 2 steps and face planted. My barrel seemed rough. Very hard to get clean between shots. 7-9 patches patch 1 and 5 with solvent. To get a clean patch between rounds. Cleaned every shot for first 20. Then every 3 after that. Im hoping the barrel smooths out soon and gains a bit more speed and accuracy. Very pleased with the rifle. Very pleasant to shoot. Probably won't last long at that rate but it's a toy and I don't mind spending money to have fun.
