Re: H- Hornady Superperformance powder, any one try yet?

Mike,

Thanks a bunch. It may be next year before I develop any more loads but you have helped me more than you know. I was glad to find out that you had started at 50 and not at 57!!!!!!!! LOL

I am printing this for my 338 Book and will be in better shape because of you.

Thanks again. This is what it is all about.

I will be in touch.

Re: H- Hornady Superperformance powder, any one try yet?

tested it some time ago and got higher vel. compared to my pet loads from Imr 4350. Its actually slower burning than 4350. I only load for my self and my son in law and his 300 wsm i was able to get more vel. from it. I didn tknow what to use for a load for his 300 wsm 4 days before deer season i get the honor of loading something i didnt have a clue of. I picked the 150 grain nosler Bt and H-414 powder worked teh load and zeroed in. The following year i tried the superperfomance and raised the vel. almost 150 fps. But keep in mind my inital loading of 414 was last minute pulling straws.

Re: H- Hornady Superperformance powder, any one try yet?

Mike33,

I think we have the same mentor. How has your chase worked out with the superformance? I am using 52gr of IMR4350 and average 3550 through a 26" barrel with the 1/9.25 twist. Don't quote me on that exact twist rate. But I am finding with that twist I can't push past the 52gr using the 85 Sierra without getting pretty nice plunger marks. I visit our mentors store quite a bit and probably met you. Hopefully you see this reply. Myself and another gentleman is starting the Superformance chase. At 3550fps I'm not sure I will see that big of enough gain to justify another load work up.

Here is my pet load with IMR 4350. Case trim to 2.155. 52gr IMR 4350. 85gr Sierra HPBT seated to cartridge OAL of 2.795.

I can push 52.5 but I'm going to run into pressure issues on warm days and we've had plenty of those during first week of WV Deer season lately.

Danny

Re: H- Hornady Superperformance powder, any one try yet?

Continuing the chase. I picked up a pound of Superformance powder the other day and a box of 75gr Vmax. Our local 6mm 284 guru likes bullets that hit, penetrate, and explodes tearing blood vessels and dumping full energy into the deer. Not pass through. And this method has been unbelievably successful for him. So here is my data here in Cumberland Md today. I'm going to list all of my data which does have some IMR 4350 data mixed in as well as 85gr Sierra HPBT.

Model 700 SPS with 26" heavy barrel with 9 1/8 twist. HS Precision Stock with a Nikon Monarch 4-16x42 scope. Pretty sure that's the scopes specs. So here we go.

Trim to 2.155 OAL 2.795
Weather 37*F Overcast

3 shot strings at 100 yards. Chrono about 10' away from muzzle.

85gr Sierra HPBT IMR 4350
52gr Average 3550fps from previous testing.
52.5gr 3604 3608 3617 just starting to show ejector marks
53gr 3640 3654 3638 ejector marks a little more pronounced but not extreme. No primer deformation at all.

75gr Hornady VMax IMR 4350 No pressure signs at all with the following loads. Room to grow.
IMR 4350 53gr 3679 3695 3670
IMR 4350 54gr 3748 3769 3773

75gr Hornady VMax Superformance No pressure signs at all. Speeds were so low at 53gr I moved straight to 57gr. Will pull the unshot bullets for future tests. 57gr showed no signs of pressure and will be testing 58, 58.5, 59, and maybe 59.5.
53gr 3551 3497 3478
54gr
55gr
56gr
57gr 3697 3706 Error

Thus far my most accurate load has been 52-53gr IMR 4350 and 85gr Sierra HPBT. Can shoot a clover leaf on good days with this load. The IMR 4350 with the 75gr VMax are not great groups. Less than 2". Perhaps tinkering with bullet depth and getting the distance from the lands correct could improve that. Groups today could have been a lot of me. Just not on my game it seemed. 57gr of Superformance shows promise. Group is tightening as I pick up speed. One hole on first two shots with a pull on the 3rd shot. Felt it when I fired.

How much ceiling I have remains to be seen with the Superformance as well as the IMR 4350 and these 75gr VMax bullets. I'm hoping 3800-3900fps. I'm almost there with the IMR 4350.

Why 75gr VMax? On paper they beat out my current 85gr Sierra HPBT pet load with Velocity and Energy at 3600fps. I just hit the ceiling with that load. Can I do better with Superformance and the 85, remains to be seen.

If I can reach 3900fps and the groups keep getting tighter and the bullet performs on deer like I think they will, this could be an incredible load. We will see.

I understand many feel this is not a deer bullet. I can tell you from family and friend experience that 75 and 80 grain explosive expansion bullets do wonders on white tail deer in this region. Typical dressed weight from 100-175. 175 being very high on the norm. 6 point I shot last year with my 270wsm dressed at 125lbs. Typical bullet for them is 80gr Remington Power-Lokt. Very explosive on impact.

Anyone else have any new data?

Hi Danny, I have been searching over the net to find someone who has tried Superformance in the .260 Rem. Any idea of anyone that has tried it? I have gotten nowhere so far. A lot of ,try this, try that, why do you want to use a powder that has no load data? I'm tired of all of this. If it works in the Creedmore cartridge,why not the .260? Any help would be a definite improvement. Thanks in advance. .....SEMPER FI! .....LARRY

Re: H- Hornady Superperformance powder, any one try yet?

Larry,

Thanks for the reply. I'm surprised nobody has stopped in and responded at all on my posts. While I am not familiar with the 260, I do have an answer for those who ask why. Because we can! It's the fun of being able to experiment within reason a safe environment.

I have load from disk that I may be able to get some info from but what I've learned from the 6-284 is that grain for grain Superformance is under velocity and under pressure. Shooting 54 grains of IMR 4350 gets substantially higher velocity compared to the Superformance with the same load. My findings verify the original posters findings with that.

Will that shoot that much different out of your 260? Doubtful but I'm not a professional at this stuff. I was safe within those limits starting out and actually will be loading up 58, 59, and 60 grain this morning with the 75grain V-Max in my 6-284. I'm trying to find that perfect load and then put the 6-284 up to save the barrel. I bought a 223 to burn powder in experimenting.

Keep in touch and let me know how things work out.

Danny
