[QUOTE="FAL Shot, post: 846094, member: 27328"] I had experience with H4350 in a Ruger M77 .30-06 that I worked up some loads for. It gave excellent results. My next load development will involve H4350 in my 7mm Mauser. I have some loads for the rifle worked up with IMR 4064 and W760. Neither have proven to be really stable with time and temperature. W760 came closest to matching Norma velocity with a Nosler 150 grain Partition, and IMR 4064 beat Norma accuracy (with a Hornady 162 A-Max, which isn't a fair comparison). FWIW, old Norma ammo from 1984 is still the standard I load against in my 7mm Mauser. None of my handloads have been able to equal its velocity, but I have slightly beat its accuracy....at a certain temperature. Nosler 150 grain Ballistic Tips and H4350 are what I hope will beat the Norma factory loads of 150 grain Spitzer bullets in both velocity and accuracy. Of course, you can't use modern lawyer load manual data when trying to beat Norma factory ammo from 1984 for a 7mm Mauser. This particular Norma load isn't even offered anymore, so I was fortunate to stumble upon a stash of it that the owner sold at a VERY reasonable price, being that he is 86 years old and retiring from gunsmithing. The 7mm Mauser is his favorite cartridge, and he was a custom rifle builder that has shot just about everything. Did Karamojo Bell just give two thumbs up from the grave??? [/QUOTE]
