Have not purchased any 300 A-Tips. Hopefully spring time! It’s hunting season now and our local long range closes Nov 15th. Ending up getting side tracked on my 7 Max build w 190 A-Tipsdid you ever do testing on the 300 A-Tips
I’m using H1000 powder with the 300 grain a-tip..338 300 grain A max ? What powder
.338 300 grain A max ? What powder
What kind of velocity can you get with the VHT-570I've been using H1000,VHT-170 and VHT-570 for over 15 years on all my 338 L with great results.
I specially like VHT-570 the best.
Midsouth offers a 10 pack on many of their A-tips! Try them and see, then you'll know for sure and remove all doubt.I’m pretty skeptical of these atips
The only consistent thing I’ve seen from hornady has been their inconsistency
This is only a 100 yards but it’s through a factory 700p. But here is this old school load I put together.
.338 300 grain A max ? What powder
I don't have that data anymore,i'm sure someone in here does.What kind of velocity can you get with the VHT-570
Sherman 7 Max based off a 7 SAUM case. Running 190 A-tip w N570 at 3003 from 26 inch barrel. Couldn’t reach over 3030 fps at 45 degrees w the slow burning powder.What's a 7 Max?
Wow, great work sir. That 90.5 load of 568 definitely deserves a second confirmation test, incredible precision and es!Have been searching for some info about loading the 300 Atips but didnt find much so i thought ill share my findings
Btw Grammar police please stay away , English is not my native language.
I did some tests with vihtavuoris N565, N568 and N570 powders.
DISCLAMER: These loads are up to Vihtavuoris published max loads for a different 300gr bullet. Start low and work up.
My coal is 3.845 inch (single feed) 0.025 jump , Hornadys coal says 3.681 Inch.
Loaded in Lapua brass with CCI magnum primers.
Rifle is a Sako TRG42 in 338 Lapua with 690mm (27inch) barrel 1:10
velocities are measured with a Labradar and the range is 100m.
Second disclaimer, im not the worlds best shooter so dont takes these groups too seriously of what this bullet can do
Also i know 3 shot groups arnt great statistically but i feel you can still see some patterns (5 shot groups in 338 is expensive...).
Starting with the N570. Firstly the 3shot grps and 5 shot grps where shot at different days. One sunny and one cloudy so i guess thats why there is a 7m/s deferens on the same load. Also the powder was 10 years old when bought, which is vihtavouris stated max shelf life. So that might explain the horrible ES , btw thats in m/s not fps! ( take it x3 for fps). So im going to have to test this more with a newer powder. But getting N570 is like finding a unicorn..
But still i thought the grps were really good and velocities high, no pressure signs. will try more at 87,6gr ~823m/s but i guess the bad ES will open up the grps at longer ranges.
Next N565. These were all shot at the same day. powder was 2 years old. Better ES than N570 but not great ( remember its in m/s).
No pressure signs. Going to try going abit higher on charge to see if it tightens up.
Lastly N568. I was hesitant to buy this as ive read that N570 is velocity KING. But as N570 is a ghost i thought ill try it.
Got very surprised over the ES and SD. ES of 1 and even 0 makes me believe this is a very even burning powder. was made this year.
To clarify, all brass are from the same lot and sized and worked in the same way. So the different ES should only be the powders.
interesting that 89.5gr and 90gr had the same velocity (808m/s) and shot quite well. Have to check that some more.
Sadly its the slowest powder of them all and i really would like to get up to around 830m/s on this bullet. Had no pressure signs so i think ill try going up in charge a little.
Hope this information was helpful for someone !

I'll 2nd that request. Even if the numbers are in m/s some of those are hard to believe.If you aren't the world's best shooter, then you are definitely the world's best reloader. Those ES numbers across all loads are incredible. Would love to hear your process.
Haha thanks for the praiseIf you aren't the world's best shooter, then you are definitely the world's best reloader. Those ES numbers across all loads are incredible. Would love to hear your process.
2979 FPS @ 38 degrees w RL-33 from 338 LM AI w 30 inch, no pressure yet. 6.5 grain swing, 100-106.5 grains.
300 A-Tips are running slower than the Berger 300 OTM
Great stuff. That gives me something else to look at. I am currently running Hornady 285's, Lapua 300 and 300 SMK's in my TRG. Wouldn't mind trying these A tips. Thanks for sharing.Have been searching for some info about loading the 300 Atips but didnt find much so i thought ill share my findings

Are you finding any pressure signs up that high? That’s cookin for a standard LM!i running 101.1grs retumbo 300 atips 27'' bartlien 3045 3sd 5es .. constent hits at 3080 yds
