Nice shows good signs though with same impact
Range Report Berger has a new 7mm bullet
- Thread starter IHFarmer07
- Start date
I just plugged in the info and it all seems dead on out to 1000 though
Past 1000 to a mile plus probably won’t be much of change either.
I’m more trying these because maybe consistency might be a bit better than the eldm’s and even more so because I’m hoping they don’t blow up like the eldm bullets have been.
This barrel has put every 175 and 180 bullet pretty much in the same exact but the 190’s being in there surprised me
I shot the 180s for a little bit what was only pushing them 27 50 but this is the first I've heard that they were blowing up my buddy is building a 7mm saum around that bullet. Ive shot it out to a mile before but changed load and havent been past 1000 with it. I do shoot the 225 eldm to 1 mile
I’ve had the 180’s to 1950.
when they make it they do great but I’ve had a frustrating amount go poof mid journey.
Yea
I had same issue with the 147’s as well.
Seems to not be happening now thankfully.
It’s an excellent performer for those longer distances.
My buddy with the 338 Norma has had NO issues with the 285’s.
I had the 147’s going 2810 in a 1-8 twist barrel.
The 180’s are currently at 2950 in a 1-8.
Thats hoe fast i push the 147 no problems. I wonder the faster speeds? My 225 2929 havent had a problem once yet. No good blowing up
My last two boxes of 147’s had 0 go poof.
they were 219 coded.
I should see what code the last box of 180’s are, I think I still have it.
They’ve definitely been frustrating, I have another 500 from a different source hopefully from another lot

Round count of 7mm saum?
Let us know on firecracking
Just picked up 2 boxes to try out in my 7 Rem Mag and maybe make the switch from the 195 Bergers so I can save those for my 28 Nosler. The listed BC's are pretty close between the two. Shooting the 195s at 2880fps, 28" barrel with Retumbo, SAAMI 7RM chamber. Didn't hit pressure until well into the 2900s. Hoping the 190 will perform well.
So I got the 190’s to 2920 today.
ballistics were pretty much exactly the same as eldm’s going slightly faster.
My barrel sped up a bit more so the 180’s are at 2950ish now.
I did have two 180’s blow up today.
with numbers at 100, 775, 1050 and 1810 yards with a speed of 2920 G7 BC of .375 jived on ballistics AE.
with a bit of coaching on position and how to titty squeeze the rear bag my Canada buddy got a first round hit at 1050 and nailed the second as well.
He’s never shot a rifle past 100 yards before.
yes my spotting scope is a tragedy.

A G7 of .360ish
Another tidbit
I got excellent accuracy with a .02 jump and a .140 jump.
I’m probably going to buy 500 of them.

I have no idea but I can guarantee a few coyotes are gonna have a bad day with these
Looks like these are pretty close in performance (BC) to the 183 SMK according to Litz's book. Not sure why I never gave them a look before. Picked up some 183s to compare with the 190s in my rifle. should have them all early this week.
What does Litz' book list for the 183 SMK?
A little odd how Sierra breaks out the BC on the 183. It's got a "Goldilocks" zone between 1720-2300 fps.
I'm running the 183 SMK in a 7 SAUM. Getting 3050 fps w/60.5g RL23. 31" 1:8 twist Kreiger barrel. Barrel still breaking in, but sub MOA out to 950 yards so far.
The 183 from Litz's book:
Above 3000 .815/.386
3000-2500 .769/.381
2500-2000 .743/.373
2000-1500 .703/.373
Below 1500 .672/.378
Avg 3000-1500 .736/.377
Above 3000 .815/.386
3000-2500 .769/.381
2500-2000 .743/.373
2000-1500 .703/.373
Below 1500 .672/.378
Avg 3000-1500 .736/.377
Pretty impressive better than berger and eldm
I may have to look into those
I didn’t know the BC was that high and a bit cheaper than the Berger’s.
Yeah i was shocked to see that. I did hear the desert shooter guy who does the videos for prefered barrels say he had some inconsistent lengths
I lucked out. After being a little turned off on the price of the 190 Bergers, and the discontinuation of 500 round boxes, I decided I should give the 183 a try and checked to see if my LGS had any. They were on sale for over 50% off. $38 CAD per box. Cleaned them out.
I tried the 183 in my 7 mag. Couldn’t get it to shoot. 8 twist.
Had 180 ELDms blow up at 3060.

What problem did you have with the 183 SMKs?
I also had problem with the 183 Sierra. The bc looks great on paper but I feel like the new Sierra Matchking line has issues when hitting transonic speeds. My loads were under 1/2 moa at 600 yards but all over the place at a mile shooting a 1-7 twist 7 SAUM at 800 ft elevation. Tried the 184 Berger F-open bullet and they were much more consistent.
The ogive radius on all the new Matchkings is secant and very aggressive compared to most other designs out there currently and may not transition well.
That's interesting. Berger describes the 7mm 184g F-Open Hybrid as having "a more aggressive ogive shape; giving it a ballistic advantage to our existing 7mm 180gr Hybrid and VLD Target bullet designs."

Took a pic of my 7mm lineup. Thought I'd share.
L to R. 145 LRX, 150 TTSX, 168 LRX, 180 ELD-M, 183 SMK, 190 LR Hybrid, 195 EOL, 197 SMK.
L to R. 145 LRX, 150 TTSX, 168 LRX, 180 ELD-M, 183 SMK, 190 LR Hybrid, 195 EOL, 197 SMK.
Not even close to the Sierra ogive radius. I think there is a fine line between aggressive and too aggressive with an ogive radius. No one other than Sierra is running a 28 caliber radius.
While Berger has pointed there new line of long range hybrid target bullets, their radius is still a hybrid design and does not transition from the bearing surface nearly as aggressive as the Sierra.
Would love to see a lot more testing done at distance with the Sierra bullets as they enter the transonic zone.
I have had numerous 180 eldm bullets explode as my chamber warms up. Out of my 280AI with a MV of 2987, 29.5" shilen ratchet 1-8 twist.
I tried the 183 SMKs this weekend at 2965. They seem to perform well inside of 1k. Shot about a 6-7" group at 980 yards.
