Pressure sign and 300wm load

[yorketransport]

Those should work great for you!

Went and shot this weekend.  Still the same flat primer, even at only 73grs of the H1000 with the hammer hunters 

So, I ran by the store and am going to switch up everything and experiment, hoping to find something great by the time spring bear gets here, which aint that far out.

I bought the only brass they had, Nosler, picked up with 215m primers and h4831sc.  Based on my googleing I think I am going to start at 68grs and hopefully make it to 71.5grs and get over 2900fps.

I also plan to try my loads that started this thread in the nosler brass with the 215m primers and see if I get the same primer flattening that I did in the Bertram brass.

Stop messing with it and just shoot!

Don't worry about the primers, there are lots of other signs to watch for. If it's shooting well and you're not beating the bolt open with a mallet after every shot, you'll be fine. Hodgdon lists a max charge of 76.0gr H1000 for a 230 OTM at 3.400" and the Hammer Hunter is roughly the same length. Nosler lists a max charge of 75.5gr H1000 for their 220gr Custom Comp bullet at 3.400" and that thing has a bearing surface a mile long!

My favorite load in my last 300 Win Mag was a 200gr Accubond over so much Retumbo that I had to have a second person help me pull the handle down when seating the bullet. Pressures were low, velocities were good and accuracy was great. If it shoots well and you're getting 3+ loadings per case, you're good to go.

I know and you're right!
I have a problem with tinkering and trying to get the best thing ever, which is a battle I'll never win, yet I won't accept it 
I will load them up, shoot them and take them bear hunting.
And then after bear season, I'll tinker until the week before my Montana deer hunt in November

You'd think after years and years of doing this crap, that I'd figure it out before the week before a hunt, when I'm scrambling out to the desert to throw some final lead, to then scramble home to load 10 or so rounds to jump in the truck and go hunt .
One day....

I’m the opposite. I like to get a good load made up and then board components in the hopes of not having to re do a new load. I hate shooting groups!

[Magnum_Willys]

Don't settle for 3" groups at 500 yards - my gawd thats over .5 moa     Keep tuning til you can get under .5 moa - that extra inch of accuracy at 500 yards is huge.  Don't give up.

back to the drawing board, kind of.
With the nolser brass,the 4831sc, and 199 hammer hunter, I was getting 2860 fps but had zero stability as the bullets were tumbling when they reached the paper.

The Bertram brass with h1000 pushing them at 3015 fps, stabilized them and I had perfect pencil holes in paper.

I have noticed comparing the Bertram brass and nosler brass, in the bertram the bullet is A LOT tighter/tougher to seat than in the nosler brass.  Both sized and seated using the same dies.

Another note.  Hammer Bullets just released a brand new .308 designed for a 1-10 twist at 196grs.  Got those ordered today and will hopefully work a load this weekend.

This bear hunt is coming up quick!

I have settled on a load for the 199gr Sledge Hammers, that I will load and hunt with if I don't get a good group with these new hunters on order.

Ive Been Using H1000 for the 300 win and My 338 rem ultra  Since they  introduced it  always stable and plenty of power and fills case almost the whole  way

I wouldn't determine my maximum load in this cool weather.  I did mine in the 80+ degree weather of the west side.  Deer hunting the weather is cooler.  That removes one of the major variables of high pressure.

Those 196’s should help
