7mm Accuracy?

[Mark Walker in TX]

That is not to say that the BIG 7's are not capable when the winds are light and variable>>just NOT as capable as a Dasher, in 7 out of 10 matches when the winds are favorable..

Hey Ben - this is where we'll simply have to agree to disagree, and was the whole reason I referenced Ken. His 200-19 simply further proved to me, that the 7s, specifically .284 Wins at least, are just as capable as anything else, regardless of condition.

I know I'm stubborn and my opinion is the minority, but I'll stick with it for now.

Mark, I saw Ken shoot that record, and I recall that his first shot was a 10, after which he made a correction and did not leave the X ring for the next 19 shots. The 7mm's can shoot for sure.

Well Mark, when you and Erik and Ken are at a 600 yard match, I absolutely MUST be at the top of my game IF I am to even be competitive! It is y'all that FORCE me to make myself a better shooter.. Disagree or not, y'all have been a GREAT inspiration to me.. Thank You Guys!! It is a pleasure to shoot with some of the best in this business!

A 7mm will not shot for me, God could build the rifle and Jesus could supply the reloading components and I still would be able to get under an inch with it at 100yds.

Now a random guy off the street could pick up a H&R handy rifle and factory ammo, sit down at the bench next to me and shoot a bughole.

I am going to have to try RL-17! What length is your barrel?

 

[Raptor]

Yep, what's not to love about the 284s.....I sure do like mine and the barrel life is great too!!

The 7's at 600 would have a clear advantage in the wind, but when things are relatively calm (e.g. - when records are set), I don't think they can shoot inside a 6 Dasher, or my favorite 6 BRX (I tied that 600 yd record last summer at a regional, and set the 500 yard record two years before with one).

It's likely that there are 7s that can shoot that tight, but I haven't seen one.

28 in. It was supposed to be 30 in. but something was wrong
with the reamer and we had to get the reamer reground and
rechamber the barrel so I wound up with 28 in.
Brux 9 twist, 1.25"no taper

The 180's grouped better at 2925





The RL-17 can get serious velocity



I reached 2990 fps but SD and Accuracy suffered
I settled on 2925 fps for my load.

I have a 32" 1:9 twist and am getting around 2750 with the 180's and 53gr of 4831sc. Looks like it is time to break out the RL-17. =)

But if you run two 20 shot strings across the chronograph with RL17. One on a cool morning the other during midday sun you'll see why RL17 isn't a popular powder for F-Class.

 

[birdog]

I don't shoot F-class
so that's not an issue for me.
I'm just trying to compete with some
guys in the area who are shooting ONE MILE.

I just had my 284 re barreled and got it back yesterday. I put my scope on it and sighted it in and did my 10 round break in process and then tested a couple of loads for it.

My first group was my old trusty load of 162AMAXs and it shot those into a .467 the next couple of groups that I shot were 175MKs and the load with H4350 went into a hole just a little bigger than Birddogs group that he posted. I believe it was a .306 and a load with 4831SC was also in the 4s. All of these are 5 shot groups. The 284s will shoot.... PS this is set up as a tactical rifle with a 4.5x14 and a 28" barrel

James Phillips and Shayne Halliburton came over Tuesday p.m. and we shot 1500 yards
and 1800 yards.
James had a 300 Win Mag.
I shot my 284 with 180 Hybrids.
I hit the 1500 yard 18 in plate on the 2nd shot. Then Shayne shot it and he hit on the 5 th shot.
Then James went 2 for 5 with the 284.

Here are the 4 shots on target. The 5 th shot is a 300 WM hit. It is the lowest shot.




We then moved to 1800 yds and shot at a pile of cow bones.
On my 7 th shot I deleted the right bone.
There was one shot that I did not see dirt fly and I think it may
be another hit in the clavicle that just punched a hole through
the thin bone.

Here is a pic after shots were fired



Here are the bones before the shots with no hole in the clavicle
