I was in Gander Mountain yesterday and was looking at a box of 375 H&H magnum loads for the 270 grain spirepoint. Printed on the box was a small trajectory table which also showed muzzle velocity at 2870 fps! It might have been 2860 or 2840, but it was north of 2800. I then picked up a box of 375 Ruger, same bullet, and it had a velocity less than the H&H, 2840 I think, but was still 2800+. I know I've seen discussions here in the past about the Hornady loads but wanted to see if anyone has recently tried these or run them through a chrono. 2870 sure seems hot, even moreso for a factory loading where they usually lean towards being slower and safe. | ||

I have not chrono'd any of Hornady's 375 Heavy Magnum loads, but I can tell you their Light Mag loads in 280 and 25/06 SMOKE...they are at the high end or beyond of what reloading handbooks have allowed. So to see that their 375 H&H or Ruger loads are warm would'nt supprise me. Gary DRSS NRA lifer SCI DSC | |||

I think I shot some of them last summer, but don't remember if I chronied them. Best I can remember they were accurate in my rifle. I only fired 5 to see how they'd shoot. I bought 3 boxes from Sportsman's guide because they were fairly inexpensive and I could use the brass afterwards. | |||

Any idea why the 375 Ruger would be loaded to a lower velocity than the H&H? | |||
|

Only idea I have is that they tested some of the Ruger ammo in 20" barrels to prove thier point. Otherwise, no. | |||

I think it's called reality... Rich DRSS Knowledge not shared is knowledge lost... | |||

I don't follow again. 'Reality' that you get less velocity from a bigger case? It is a curious observation Prewar. My first guess would be differing test barrel lengths. But perhaps their proprietary top-secret powder actually works a smidge better in the slightly smaller H&H case?? ![]() Cheers, Canuck | |||

Reality? Nobody here has chronographed any of it? I shot some of the .375 H&H pixie dust loads once, and got about 100 fps less than the packaging proclaimed, and about 2 MOA accurracy instead of the 3/4 MOA my handloads gave in the same rifle. I didn't write it down. I was laughing too hard. Packaging print hype is less of an overestimation on the .375 Ruger. That is the explanation. | |||

Good point RIP. I have not chronied any of the 375 H&H Heavy Mag loads, but I have verified the 375 Ruger Factory ammo claimed velocity as being 'reality'. ![]() Also, the 375 Ruger ammo is not labeled "Heavy Magnum". ![]() ![]() Cheers, Canuck | |||

I think it's a clear case of "H&H envy." ![]() | |||

......Even in the Heavy Mag , that would be Quite fast for the 270 in the H&H ... However it brings up a good point about the Extremely versitile 375 Bore magnum velocity cartridges ........Long ish range shooting .......With a 270 gr spitzer that becomes a 4-500 yard rifle ....No need for a littler bore .. ![]() .If it can,t be grown , its gotta be mined .... | |||

Looking at Hodgdon's loads for the 375 Ruger, they don't have any loads that are getting 2840fps with a 270gr bullet, but there are quite a few loads listed that are over 2750. If you look at the pressure of the max loads, almost all of them are below 60k psi as well. I think that it is intersting that most of the Hodgdon's max loads for all bullet weights seem to be well below the 62k psi MAP. When I looked at the max loads for the 338-06 on Hodgdon's website the other day, almost all the max loads were at pressures near 62-63k psi. It sort of had me scratching my head as why they gave data so hot for the 338-06, but seemed conservative on the 375 Ruger...or am I am missing something here? Not that I would load the Ruger any hotter if I owned own, but it just caught my eye. It looks to me like all the fears that handloaders wouldn't be able to get close to the factory fodder seem unfounded. I guess the point I am trying to get at is that ,while the factory ammo's velocities seem hot, it doesn't look to be loaded to the "Heavy Magnum" levels. | |||
