.300 Win.Mag. 190 SMK, H1000

[bbarber25]

Well, another blessed year and hunting season. Was able to take my first bear and a decent bull this year. My .300 with 215gr. Bergers did fantastic, as I’ve come to expect. Most importantly, I was able to spend a lot of much needed time in my “safe place” up on the Unc here in Colorado, with family and friends. Super thankful for all their help, support and resources.

Now it’s time to screw on my summer/practice barrel on my win mag. Have a whole bunch of 190gr Sierra Matchkings I’d like to use up. Would appreciate any advice on where to start with H1000 for a load as well as what jump/jam you’ve found this bullet likes.

Few pics/videos from this years success!

I thought the 300winmag is Obsolete

J/k I love mine. My first rifle was a 300winmag and have always had one.

I loaded 190 SMK and VLD in mine years ago.

My notes show I went up to 81 gr H-1000 for 3,065 fps from a 24" bbl. with the 190 VLD hunt.
Accuracy was not as good as I hoped. Tried IMR-4831 and reached 3,100 fps with no pressure signs, but again accuracy was not worth more tinkering.
Tried H-4831sc and between 72 and 73 gr it all came together like I hoped. Tho Velocity was fairly anemic, at just under 2,900 (2,893 fps to be exact). Highest I went was 74.5 gr H-4831sc.

Then I used the same H-4831sc load with 190 smk when I ran out of the VLD.
