I built a rifle around that bullet, so I'm running it well within mag length and kissing the lands, with the bottom of the bullet shank just below the neck/shoulder junction.

That bullet certainly is an animal, and even makes the 162 look silly in the wind. You can definitely tell the difference between the two when they hit steel. When the 195 hits it sounds like somebody hit the plate with a sledge hammer.

Jordan,

I always start load work in the lands .020" or so. Both dummies were set up for that, with the bullet's pressure ring at the n/s junction too. The Bergers were about .020" under box length, the SMK's about .050" over. I've moved my seater out .010" at the 450 round count. Smart move on my part for not adding the third bullet to the mix for testing at this point. Have you tested jumping the 195's?

I just ran another side by side ballistic comparison, the 183 .713 BC vs the 195 .755 BC, with a WAG velocity loss of the 195 at 125 fps. A virtual tie across the board at 2K, except the SMK's 3 MOA less drop.

From a LR plinking standpoint, I think the SMK wins, edging the 195's in drop and cost. But from a hunting standpoint, my 180 Hybrids run about 2 MOA behind the SMKs, so the 195 wins there. However, I pointed my Hybrids, so the true figures are likely worse, as I don't want to shoot pointed bullets for hunting.

I was about to replenish my Sierra stash, maybe I should re-think the 195's.


aalf,

I do the same thing by starting into the lands about 0.020" and working backwards if need be. I have jumped the 195's a little bit, no extensive testing by any means, but the little I did work with the bullet jumping about 0.060" off the lands showed a lot of promise. A starting load produced a few groups of 5 shots into about 0.5-0.75 MOA, from a couple of different rifles. It's been a very easy bullet to work with so far.

In my rifles I usually get about 100 fps more with the 180 Hybrid than the 195, just FWIW. Though you're right about the cost. The Sierra or a Hornady would certainly be more cost effective when burning through thousands of the things, though the 195's wind-cutting performance and impact on target are pretty satisfying smile

Honestly I'm not sure you'd see much difference between the 3 bullets in all practicality. I'd probably run whichever shot better/was cheaper for plinking, though it wouldn't hurt to try a box of the 195's just to see what it'll do in your barrel. I'm definitely liking the idea of the 195 for LR killing, though ironically the only game animal I've killed with it so far has been a WT buck at 100m *grin*

Very nicely written, great pictures. You are very handy with doing your own stock work, the bedding looks great. Glad to have been able to help out, Tim.

My 7/300WM works great with RL25 and the 160 NAB. 3225 fps and nice tight groups.

You get tired of that, we can ream it out to the 7mm338RUM!

Another reason for the 7x300 was I had a couple left over 8 pounders of H-1000,
that should be been perfect for the cartridge.

Priming the new Hornady brass, I was surprised how easy some of the primers seated. After the initial firing, fifteen or so never made it to round two, and that number again after round two. I have 60 some left now, still going on their 4th & 5th firings.

Shooting at 200 yards with the H-1000/183 Sierra SMK combo, 77 grains yielded a best group of .880" at 3147 fps.

Best group also, at 1.1", was with the same 77 grains and the 180 Hybrids at 3175 fps.

I went to 80 grains with both, and got the first tattoo, so felt I was OK at 77.

I loaded up a bunch of both at 77 to test seating. All loads were .020" in the lands, and I went off in .015" increments.

The Sierra didn't like getting off the lands at all.

The Berger Hybrids lived up to their reputation as not being fickle in seating preference, laying in a nice 1" group .080" off the lands, leaving plenty of room in the mag box for hunting.

So the results met what I was going for, the Sierras for play, the Bergers for fur.

Except.......

I didn't care for the Hornady brass, and while I got decent accuracy,
it seemed I could never got consistent results.

So, I sent back the other 100 pieces of Hornady brass, and ordered some Nosler.....
world of difference. Luckily I always use my Sinclair priming tool, as the 'ol Lee Auto-Prime woulda fell to pieces trying to seat primers.

At the same time, I had a burning desire to try some R-33. Just so happened the closest supplier had an 8 pounder in stock. After another round of testing with both bullets, I settled on 82 grains with either giving single digit ES's at 3125 fps.

I went back the next day and bought another 8...... wink

FYI.....for the new Sig rangefinder fans.....

The 2nd closest jug, at 625 yards, the orange one sitting just on this side of the creek bank, the Sig could not pick it up to save it's ass......

You'll like the Sig, as you don't shoot beyond 600, and you're not worried about ranging a coyote laying out in the middle of flat ass nowhere. It's reload speed is amazing, and does damn good to 1K for the most part.

That day it struggled ranging on the jugs as I went further up the hill, and couldn't get the last couple, which was 1K or so. Ranging into a hillside is a piece of cake, the level schitt on small stuff is a problem.

Got it. Will it pick up individual deer?

My Leica flunked that last year in Kansas.

Like most answers....it depends....900, 1200, 1600?

I had the old style 1200 and liked it, but when I built the big 338, I was outshooting it's capability, so I was forced to update to the 1600B. That ended up marginal for my needs, so I updated again.

The sunlight plays a huge role in getting consistent readings too. I haven't had the opportunity to range many deer with the Sig yet, but the small testing so far is favorable.

As inexpensive as they are, you can buy one, give it a good workout, and peddle it w/o losing your shirt if it doesn't meet your needs.

Good. Thanks. Scott said his findings are like yours. I will give one a go.

I was pretty frustrated in Kansas last year...even short readings were tough on the deer.

More play time.....

Filled up some more jugs with colored water:

Backed up a little bit and got set up:

Not really the best day to be out there, as it was cold with the winds huffing & puffing more than predicted. But worse yet, it had rained a little bit, which made spotting impacts sketchy at best. The bullets were just bombing out little divots. Managed one kill for my effort though.

Aalf what do you like about the Nosler brass v the Hornady? What makes groups/shooting with the Nosler brass more consistent?

Judging from your other posts Al, I take it the Game Warden wasn't the ticket? Pros/Cons; the good, the bad, the ugly.


I never thought I'd grow up to be a grumpy old man, but I did, and I'm killin' it.

I had a 375 Ruger, & I thought the brass was great.

With this brass, the primer pockets were too loose on some right out of the gate. The Nosler brass has some TIGHT pockets. Maybe it was just this lot number, I don't know.

It was the R-33 that seemed more consistent, not the brass. I'm still shooting 60+ Ruger cases.
