I did but you won't get the velocity of RL33 or N570 . It will do a little better than H1000 though......Rich

I got my hands on some N570 yesterday so ran a few over the chrono today to check out max with the 225's. Here are the results below. It appears that there may be a good load between 3050 and 3100 but will run a ladder and more testing later. You can see a VERY steady climb up thru 84 grains. There was a slight extractor mark at 86 grains

This round has been on my mind alot lately. Glad to see positive results with 225's. Have you found the number of times the Hornady cases can be loaded with a max or near max load before primer pockets become loose? I've been looking at 338's but for some reason i keep coming back to your 30/375 S.I.

I think I could run these at 3050 8 loads or more. If you run the numbers, this load has killing power at 1 mile plus!......Rich

I'll have to purchase some 225gr ELD M bullets and test them in my 30/375 S.I. I have a shorter and slower barrel than you. A 9.5 twist Krieger - 26".
BTW, I don't experience unacceptable temperature sensitivity with RL 33 in my hunting temperature range. Rarely ever see 70F here while hunting. Perhaps that's the difference in my experience and conclusion, compared to others concerns about temperature sensitivity.
I've tested RL 33 in both the 30/375 S.I. and the .338 Rogue from 0*F up to 70*F, enough to generate confidence in the data. From 40F to 65F (my hunting temperatures), really no issues from my perspective.

That is interesting Paul. I think I will like the N570 the way it is looking.......Rich
I just checked my field-tested G7 BC value for the 215gr Berger Hybrids I've been shooting in my 30/375 S.I. My bullets are meplat-uniformed and countersunk with the Kevin Cram meplat uniforming tools. Berger specs a G7 BC of 0.354 for their 215gr Hybrid. I use a G7 BC value of 0.330 on the meplat-uniformed bullets. A reduction of 6.8% reduction from the factory value.
So by swapping over to the 225gr Hornady, I'll improve my G7 BC value by 18.5%. From 0.330 to 0.391. That's a substantial improvement! I think you make a good point and recommendation Rich. I'd been waiting for some ELD-Xs, as Hornady has been promoting them as the better hunting bullet. If the ELD-Ms perform as well (maybe better from your perspective) than the ELD-Xs, then I should wait no longer. Time to place an order... see how they shoot.
The Hornady BC values are dead nuts on, correct? Should be if they're using their Doppler radar equipment...

Have you checked out the hornady page with all bc values? They have 3 different bc' s depending on speed listed for each bullet. I've been using the lower (mach 1.75) value for all the different bullets I have used so far and been on. I believe Rich has used the higher value and no issues either. I guess check it out and test for yourself.

I posted on another thread that I am shooting the ELD's because they are making now what I was trying to do years ago, and they do it far cheaper than I can make them! I have shot them out to 1300 yards (the 143's) and about 880 so far with the 225's, and have made NO corrections for b.c. I will give "my opinion" on the difference between the ELD's and the 215 Bergers. I think the 215 is better at closer ranges because they don't open right away and probably cause less entry damage than a tipped bullet. The ELD will open fast (remember the tipped bullet of mine that you shot the caribou with)
I believe where the ELD's will truly shine is at long and extreme ranges. They are very much like the ones that I make which perform best from about 600 yards to wherever 1300 fps is? Usually farther than I can hit anything! Don't get me wrong, I think both are good bullets but the ELD's will be better, and more consistent, when velocities drop below 2000'.......Rich

Good info. Thanks guys.
I do remember the caribou and what you say is consistent with my experiences with the Bergers versus tipped bullets.
The 225 is heavier and may have less MV and impact velocity at the closer ranges. And the butt end of the Hornady plastic tip is probably a smaller diameter than your aluminum tips.
So perhaps those two items will be cause for some reduced close range entry side splatter.

Hmm? Does this hold true 285 Eld M's as far as BC and speed changes?

In your testing, was it ELD-X bullets that performed same as Berger's?
What about ELD M?
Sorry if I missed something
