Just checked case capacity now, and its identical with yours.96,3-96,5 grains of water
I`m testing retumbo now with 220 Lapua scenar L bullets in Norma brass. Best accuracy load so far is 80 grains of Retumbo for 3000 fps.Will test your Hodgon 1000 load with 215 Berger
Wow! That should perform identical to mine. My case capacity is 96.4 grs. of H20. Mine really likes H1000 for accuracy. It won't get you top velocity, but is VERY consistent. I once shot a 1.18" 3 shot group at 880 yards with 80 grs. behind a 208 SXR. It also is very fond of 79 grs. behind a 215 Berger hybrid. Retumbo will get you another 50-75' with about 81 grains for near 3100. RL33 is the top dog for velocity. I shot some 230 Berger OTM's at well over 3100' and reached 3300' with the 215's and ran out of room for powder before max pressure. I use standard primers with the H1000 loads. Either 210's or BR 2's..........Rich
I have made a wildcat very close to yours 30-375 SI.Mine is based on 300 Blaser mag with less body taper and a 37.5 degree shoulder. Case capacity is 95-96 grains of water. My rifle (Sako 75 with a 28" LW 1-9 twist barrel) is just finished, and im ready to start load development in a few days. I can see yours is extremly accurate.What powder do you recommend for the heavier 215, 220 and 230 gr bullets? I was thinking REL 33, but cant get hold of it :/ What about Hodgon 1000, REL 22 or Retumbo? Which gives you best speed and accuracy?
I had read through final design and the load data and I'm interested to find out more. I live off of Seltice by the Hockey Rink in Coeur d Alene, I see that your in North Idaho just not sure which town. If there's a chance to check out the 6.5 SS I would like to and find out more about it.....
I've been looking for a light weight rifle with punch and it seems that you have designed it.
I tried to put my yahoo email address in but it wouldn't let me....
Rich,just learned of the Sherman and would like to know more about it. Recoil compared to .270? How Many yards until the ft lbs decrease to 1000? Velocity from muzzle to 1000 yds with 140 grain? If possible would like to call you about it. Thanks for your help.
