Show me your 7mm long range groups.

[Terry]

Many are shooting 6mm rounds because they group better that 7mm at 600 and 1,000 yards.
Show me your 7mm long range group pictures.
Do 7's group as well as 6's?

Thanks!

Terry

Don't be shy.

Terry...maybe not shy, but just modest! Let me see if I can help you gather up some long range benchrest photos, or otherwise, from your benchrest friends. Possibly from Jerry Tierney, who fondly uses 7mm for benchrest competition out in CA.

I am a F-Class Open shooter, and I shoot 7mm from 300 to 1000 yards. However, I do not maintain shot group pictures for those distances in our shoot-pull-mark scoring routine. Also, I do have a 6mm DASHER, but wouldn't dare compete with it in my sport at 1000 yards, and I'm reluctant to use it at 600!! Might use it at 300 yards in a fullbore or mid-range match? I much prefer the Winchester .284 for the short ranges.

At attachment is a 7mm shot group for you that I recorded last year while working up a load for my 7mm short magnum team barrel for use with the US F-Class Open Team at the US World F-Class Championships held this past August at the Whittington Center, Raton, NM. Sorry, it is NOT a long range shot group like you wanted, but simply a 200-yard load development group...for you to use as a comparative to the 6mm and at a distance you would expect the 6mm to really shine. You specifically asked if the 7mm can group like the 6mm. The group is not the 5-round shot group that you commonly shoot, either; rather it is 10 rounds total fired slow fire, and without regard to 200 yard conditions. A barrel tuner was not involved.

I have no idea how many competitors shot 6mm either in the individuals or team matches at the Worlds, except for the one gentlemen that was squadded on Day 2 of the individuals with me. He did not fair well with his 6mm XC. Despite the awesome groups that some of your friends achieve at the long ranges with the 6mm, I did not see any 6mm's in the top 20 at the F-Class Worlds shot at 800, 900 and 1000 yards while lying prone on the ground with the same type front rests/rear bags you use on the bench. Yet, the Berger 7mm 180 grain Hybrid dominated that group. One does run into the 6mm's at the F-Open short ranges, the pesky little rascals!

I too shoot F-Class in both mid-range (600) and long range (pamla and 1,000 yard). We see a fair amount of 6mm (BR, BRX, and XC) at 600 yards at my home range, but they are not as frequent at Palma or long range.

It does not seem to be a question of grouping capability (at least from my discussions with various shooters), but more of bucking the wind over the course of a 20-shot relay.

Terry, I don't have pics but at Va. state match over two days and 4 matches my agg. with the Dasher was 2.8" and a score agg. of 50 with 2X at 1000 YDs. Over the year it shot 2- 6 match score records, with 600 pts. total and the Dasher had 596pts. our 10 ring is 7" ……. There were a lot of 7's and 30"s…… jim

 

[Erik Cortina]

Terry, what is the intended purpose for your build?

 

[Terry]

Erik

I shoot 600 and 1,000 yard benchrest. I have a 6 Dasher and a .284 Shehane.

Looks like you're all set then. Looks like the Dasher does well in LR BR, for F-Class, the Shehane would be the best one.

I'll see if I have any group pictures I can post.

 

[johara1]

Eric, I don't post pics. but draw a circle 2.8" and put 20 dots in it…... ..jim

That would be a world record in F-Class if you could keep them centered!

[dannyjbiggs]

It would appear that someone doesn't want 7mm groups posted here.
I posted a couple pictures over an hour ago and they have disappeared.
Maybe I pissed someone off? ? ? ?

Nope...See data base restore issue under "Main Message Board"...they lost it for you!

[jamesh]

Thanks Dan. I had not seen that.

 

[jamesh]

IBS 1000 yard match targets below shot with a 7mm SAUM. I am reasonably sure they were both shot with Hornady 162 BTHPs

Top one measures 3.437"
Bottom measures 4.084

 

[johara1]

It seems my post disappeared also….. jim

Yes, but yours had nothing to do with the database restore! ;D

 

[dannyjbiggs]

:-\Everyone's is gone...now we have to fret with restoring it. Can't recall a word that I wrote. :-[

[Terry]

My best 7mm was a 2.5" 4 target agg at 600 yards.

Looking to do better.

James groups are great for Byers. The wind that we shoot in is crazy. This tyrant at state when I got out of my pickup at 7:30 in the morning it was blowing 48.7mph.
