Berger 7mm 190gr long range hybrid

[birdog]

I’m shooting in Fclass Open with a 7-270 WSM and I use Berger 184 Bullets . I have quite good results pushing them to 3140 FPS on a 9 twist barrel. I’m testing new 190 Berger with a 8 twist barrel but I can’t find any accuracy at high speed . I can push them easily to 3070 FPS but no way to find good accuracy . If I slow down to 2950 not fantastic but acceptable accuracy . Any help ?

Go with the accuracy. The increased BC of the 190 should help you

Which powder? I’m now jamming them with imr 8133(basically retumbo) and I am in the 2970 range and yes, not easy as 180’s, but this all I have...BR2 have been better for me also

Haven’t got them to do much of anything fast. Best accuracy seemed to be in the low 2700s

That little 284 ain’t enough for the 190’s.

They don't use ballistic tips because they do not "point" that well.

Very true

Probably need to slow to 28xx with sc

New bbl, one last effort with these f’’’kers
First groups shot, will try to repeat

they are in stock everywhere…..

they are in stock everywhere…..

Maybe there is a reason for that.

Some potential, liking +10 today

decent tail wind today

Maybe there is a reason for that.

Absolutely, they are not easy

8.5 twist is what I tested with.

Just used up the last of my test bullets and finished with my 5 shot groups all under 1/2moa. The best had an ES of 3 and an SD of 1.2 with a 2.81” total vertical at 1000yds. While I’m not totally happy with the 2.8” vertical I have no doubt I’ll get it under 2” once I have more bullets to tune with. Overall I was REALLY happy with the 190s and can’t wait to use them in the real world later this year.

FWIW I was getting on average a 49% retained velocity on target at 1000yds.

Hi John..
Are you still using the 190gr hybrids and do you see any advantages over the 180gr or 184gr hybrids..??
There maybe still a few boxes left on the shelves over here but they'll be gone shortly as there probaly the only 7mm berger left on a few shelves..

I actually stopped using them quite a while ago and went back to the 180s however I would shoot them if it all I could get ahold of but would definitely shoot 180s and 184s first given the chance.

Do you mean if you could get hold of them..?
I think there was a typo..!

I really like the 190 Berger’s but I shoot Steel and ELR with them.
It’s pretty amazing how far you can shoot them and the performance at some considerable distances.

I can understand why Fclass types would like the 180 hybrid(a fantastic bullet) and 184 more.

Yes i have tested 500 rounds now in a 7mm SAUM AI. Low node 2775 high node 2911. All with H4831SC-57.5 low high H4831SC 58.8 grns. An yes they shoot well. I have another friend shooting them in a strait saum @ low node. His is shooting quite well. Shooting inaccurately at super fast speed never seems to work well for long strings of fire.
My plan is to run them @2911fps. Its a good speed with a very high bc bullet. Hope this helps out. Also @. 240 .250 Fb seems about perfect for these bullets.

Hi here I just started to shoot a 7m saum with 190 Bergers hybrid targets in Australia anymore info on the load testing
