F-open cartridge for lazy people

[marchx]

.......... and pick one that suits US shooting practices and conditions as you'll presumably continue using it back home after the 'Worlds'. The WSMs suit our conditions and shooting format, but the 7WSM hasn't been successful in yours. US String shooting when combined with high ambient temperatures produces too much chamber and barrel heat for best results and kills barrels in short order with this cartridge. I imagine the 7PRC is a good option, as was the 284 in the 'Worlds' at Raton back in 2013.

I live in continental Europe. But thanks.

I'm playing with a 6 BRX - First "guess " load shot on the waterline at 600 today (20 kph switchy wind) at 2888 fps and a low ES. Ill try it at 800 next weekend. Won't take much tuning.

After many years and barrels with the 6brx and 107gr bullets. 2990fps was the target velocity.

If this cartridge is specifically for LR matches then any of those 6mm's projectiles will be at a great disadvantage unless wind is nonexistent. One of the 7mm variants or even 30 cal would be better suited.

Depends on what competition we are talking about but in LR BR its the 6BRA. For F-open its no 6mm at all. Lazy men dont break records

You have a talent for words. They certainly don't set records in competitive shooting but they are pretty successful in politics.

I agree with most of the postings saying a BIG 7 is the best for F-Open. I shoot a 7mm Sherman Short and .300 WSMs. Both are excellent>>>but I am growing weary of fighting recoil and torque. So, If I had to settle on just 1 cartridge / caliber, it would be the 7 Sherman Short. When I first got mine, I had to fireform "unimproved" Sherman brass to the desired 40 degree shoulder. Now Rich has come out with brass that has the 40 degree shoulder. Oh and it is ADG brass which is excellent! I have found 3 powders that work consistently well in the Sherman with 180 / 184 Hybrids. RL23, VV N565 and even H4350. I can't get RL-23 so I tried H4831sc. It "works" but not as well as RL-23. But one that does work is N565. It is a VERY accurate cartridge, easy to load for and is an "improved" cartridge right out of the starting gate. Try it! It is "ready made" for the F-Open shooter.

I am lazy and that’s why I shoot 6br. Even with basic tuning or no tuning it shoots very well. With proper tuning it shoots great.

Is there an f-open cartridge that is equally easy to tune?

6dasher for 600 yards
.284 for 1000 yards

6dasher for 600 yards
.284 for 1000 yards

That was my primary thought 3 years ago. Now, I see more and more people switching to magnums for 1000 yards. Does it make sense nowadays to build a new .284 instead of e.g. 7PRC or 7WSM?

Talking with a customer yesterday, his words not mine....
"Running a 6.5-7prcw @ 2850-2880, is right where I ran my .284."
That being said if you have a standard .308 bolt face run a .284, if you have a magnum action run the 6.5-7prcw,
7 rsaum.

I'm rebarreling my dasher to a 284 win or shehane haven't decided yet. I love cleaning targets at 1k with the Dasher but it won't hang with the 7s

 

[ChrisNZ]

..6.5-7PRC but I heard too many complaints about it being a finicky cartridge.

We had our Nationals last week and the top two were 7 PRCWs, both hammering at longs.

That 284 would be a Shehane and not a straight 284 Win which likes 2770-2820fps.

I heard Tracy Harrold in a podcast comment that the magnums won't shoot low single match scores like the 284s but will agg better over the course of a long match.

If I were just getting started in 1k F-Class, I would build a 7-6.5 PRCW. Very easy to tune, easy to shoot, and is easy on brass if you don't overpressure it.

I believe I saw a comment here {on the forum} by Alex Wheeler about the 7PRCW doing everything a .284 does, but better… Certainly just the issue of brass availability puts it well ahead of a 7 SAUM and that is a positive thing and barrel life is just a bit better as well.
Berger 180 hybrid or 184’s run at 2’850 seem to be the ”go to”.

If you want to run them “Hot”, say 3’000 or more than you better get a Rollsizer to help keep the “clickers” away…

Lazy people don’t win, if winning is not important to you just shoot the 6 Br., have fun and stay lazy

 

[Ranger188]

From @johnnyi chart, 86% used some sort of 7mm (284) cartridge.

 

[Sandstorm]

sort of 7mm (284) cartridge.

Yep...works for me.

 

[rardoin]

Dasher holds more 600/1000 yard records and wins than anything else lately. And now, having said that, I cannot remember what website I read that on. With the ranges and record match data.

In F-class competition? I guess I need to get out more often...

 

[Rset]

Depends on what competition we are talking about but in LR BR its the 6BRA. For F-open its no 6mm at all. Lazy men dont break records

Seems to me that shooting a 6mm in F-Class long range would be anything but lazy.
To be competitive, you would have to tune better, read wind better, and have better consistency all the way around. In the end, they who make the best wind calls break the records.
If anything, shooting the new latest magnum wiz bang cartridge with the least amount of wind drift would seem be the lazy option.

I agree with you 100% in that regard. But if you other guy works as hard with a 7mm you loose.
But my answer was more direct to his question of easy to tune cartridges. Thats mostly a myth. I wont get too deep into that though.
