Slight derail but would VV N570 be suitable for a big 30cal?

Absalutely!!!

Wow, well I guess I better get some N570. I use 95g of RL33 with a 230OTM in my 300Rum at 3000fps(been to 99g). Some of the RUM loads on the net are really hot.

N570 is a double base powder as is RL33, they have a nitroglycerin component added.

BJD here is a link to another burn rate list. I think it is the easiest one I have found to follow.

Might be a little warm but that's very promising!!! It's only 100FPS behind my 300LM IMP with the same bullet and barrel length. I'm positive with the extra capacity I'd exceed 3400 by some margin.

The brown truck showed up with a new RCBS 300WM full length bushing die and a .303" bushing. With that bushing and a Redding +.004" shellholder I am getting .002" shoulder setback and about .0015" neck tension with my W-W brass. I also picked up a .307" bushing for the Federal brass- it may also work for the Remington brass.

Sometime soon I will get to go try them out.

Today i shot the ladder of seating depths and the winer was 3.61. My lands are 3.65.

I had two one hole groups and pulls the third before i finished with the 1/2".

So my personal load development is done.

June 2nd ill try the 270-300 Win Mag on wild boar.

Nice job BJD! I made it to the range yesterday and shot the Barnes 130 TTSX with VV N570. Max load velocity was up in the mid 3,500s. I have it written down and will post exact data later.

I am also done with load development. Let us know how it performs in the field!

WI HAD A TERRIBLE DAY AT THE RANGE saturday. The wind was blowing, but i couldnt keep the Berger 170s under an inch and a half. Same load, same can of powder, same seating depth. Unreliable results.

I brought the Cutting edge to the range today and i will hunt with this bullet. It is more consistant for me.

These were the Cutting Edge loads with 4350, and the wind was still blowing today.

3425 fps. 140gr.

I just noticed that Midway has the 170gr. Berger .277 EOL for $37.32 marked as Clearance.

Great shooting BJD with the cutting edge bullets! Let us know how they perform on game.

I just ordered some of these Rifle Reloading Bullets | Peregrine Bullets

I got the 130gr Plainsmaster and Match so hopefully they will work with my 10 twist.
