Very good result. At those speeds you have a 1000 yd Elk rifle

Yes but I will use the 205 SBD2's in this one. I did this load work for a couple of 30 Shermans I did with a 10T. But you are right. These speeds will be great for 1000 and in.

Well I was able to get in some range time today with the 27 Sherman mag and the 150gr bulldozers. Here's what I got.
Average velocity with 80.6grs of H1000 was 3550. And 20 thousand off the lands.

That's some serious horsepower for a 27 cal. What is the Sherman mag case based off? Similar to a 27 Nosler?

It's off of the 300prc case

1400 yards to minimum velocity. Nothing under the BIG 338s does that.

Excellent group but the speed is screaming! You have a bullet that can take the stress at close range (<=200 yds) but remember that strange things happen with very high speed impacts on game. Guys have seen this with Allen Magnums and Rums shooting light for caliber bullets in this 3500+ fps muzzle velocity range. I would not necessarily change your load because it shoots really accurately but rather use your ballistic app to see at what distance and under what conditions the bullet speed falls bellow 3000 fps and consider that distance as a point blank distance since beyond that you will see more predictable bullet trajectory through your target and most likely less meat damage. Great data though. I would be very proud of it.

Tested for max charge today with the 150 BD2/H4350 in my 7SS
57.5 gr 3078 easy bolt lift
58 gr 3153 VERY stiff bolt lift
Very similar speeds to the 155 Hammer Hunter. Hoping to find a node next around 57

What twist in your barrel? Is this a "b" chamber or the original? Just curious is all. The twist is what matters. I run an 8 twist in the 7 ss' I have built and run the 160 BD2's . The are very accurate. I know my twist rate is lacking but at 6000 ft they seem to fly well.

Looks like at 57.5 gr of H4350 you are at max safe load. You might try StaBall6.5 whch is very temp stable, slower burning, and might give you more speed if you want that. The jump is good.
I am surprised you did not go the Kirby route.

Well brother, I already had to sell 7 rifles just to afford one Kirby lol believe me I would have loved to!I am surprised you did not go the Kirby route.
