QL request for 300 WSM 165 NPT. Which powder will get it don

[mjcmichigan]

I’ve been using IMR 65.5 grains to move a NPT 165. I’m getting about 1”give or take a little.

I’m wondering if H4831sc is a good option. For that matter any other powder.

For some reason I don’t get, having trouble finding a H4831 recipe for 165 bullets.

Can I get a QL report which list max safe charge for model 70 24” 300 WSM. Using CCI mag primers and a 165 Partition?

Thank you in advance, Mark

So, when I shot a 300 WSM a bunch, I used RL19 and RL17 quite alot. My best friend has a 300 WSM that we developed a load many years ago with 71 grains of RL19, CCI250's, 165 grain Accubonds and WW cases. It was easily a 3/4" load with a little seating depth adjustment and ran a cool 3150. He just called me a few days ago and he took a nice 5x6 bull at 724 yards. We shot this Summer out to 800 and it was easily around 4-5" most days at 800 and sometimes less.

I loaded him up some fresh cartridges for his trip, but he said it worked like a charm. So 19 get's looked past alot, for me and a few others 19 has been really good. I haven't noted temp problems but we're usually not into the extremes with most of our hunting anyhow.

Good luck with your load work!

Thank you Dr Mike and Scotty.

I have from 165’s sitting over H414 I think 68.0.

You might recall I had a problem with this guns consistency.

When I was working with 180’s, didn’t matter, NBT, SGK, HIL HSST, I’d get two touching or nearly touching, then one 2-4” left or right. Always SubMOA vertically.

Well, the 165’s are always less than ONE MOA horizontally, but I’m seeing the verticals spread.. same way.. two nearly touching then 1 high or low 2-4”. So the weird pattern rolled 90 degrees.

Again NPT, SGK and HSST all doing the same thing.

Barrel free floated ok.

Going to remove the muzzle brake and see if that changes how it behaves. It’s good enough to kill a deer at 100 yards, by the time I get it to two hundred I worry we could wound one.

I might have helped a fellow shooter today.

Christenson arms carbon fiber braked 300 WM with a NF scope. Is getting frustrated nothing is grouping. 165’s to 210’s. Several brands.

Told him if his scope bases are not tight, nothing will group… well, 5 minutes later.. out comes the torque driver… there was a little wiggle on the front mount.

I looked at it, and the base had wear from recoil on the back of the base bottom. Also, one of the screw holes on the receiver went all the way through. Never saw that before. If I stuck my finger in the receiver, I could see finger through the screw hole.

He’s supposed to go on an elk hunt in Montana next week.. getting down to crunch time. He has a 12 # target gun he could take instead.. he’d really like to get that CA working.

The other thing I floated was remove the brake and see if it groups better.. which I haven’t done on the said problem 300WSM.

I’ll probably get that done at lunch tomorrow.

Did get a nice 3030 load working and a new optic on the 45/70 sighted in.

I’ll use one of the levers for white tail.

If I don’t get the 300WSM working well for 200 yards, I’ll give hi. The 3006. It’s solid.
