[QUOTE="MontanaRifleman, post: 500754, member: 11717"] H1000 was recommended to me for the 177's by another member who has been shooting them almost 2 years now. He's taken game with them at moderate distances. Retumbo is to slow. I've had very good sucess with RL17 in a couple of other cartridges and though it might be a good candidate for the low pressure bore riding GS 177's. So far it's given me better results than H1000 but I may not have pushed H1000 far enough. If H1000 can give me equal velocities with RL17, then H1000 is the logical choice because it's probably more stable and it fills the case whereas RL17 tops out at less than 90% capacity. That being siad, I'm having my next bore nitirided which should result in even less resistance and pressure which would be better for RL17. There's another member who said he got 200 fps more velocity out of his nitrided 300 RUM bore. You could try H4831sc, but if your getting good results with 104 gr of H1000, I doubt it would be any better. Only way to know for sure is run it up. The JLK bullets are great bullets, but really no different than the Bergers. Same jacket and same shape, except for the LBT's. the 210 LBT probably has a better BC than the 210 Berger, but probably not as much as advertised. It's probably somewhere in the middle. The GS 177 has a BC of .638 @ 3300 fps and the overall average G1 BC from is probably about .610 This is calculated and not fire tested. I will be sending Bryan Litz some of mine in the near future for him to test and then we should have and actual BC. I'm guessing probably in the .6 range and maybe a little higher with MV's in excess of 3500.
