300 yard benchrest gun,... what would you shoot?

Well I got a jump on one of next years projects because my barrel maker got my tube done really early. This was suppose to be my long range steel shooter but from what I'm seeing so far I may just shoot it in next years matches at 300. I built a 6mmXC around a 26 inch 7 twist X-Caliber barrel and with only 72 rounds fired for break-in it shot this 200 yard group with no tuning yet. Peterson 6XC brass, Hornady 105gr HPBT seated at .050 jump, RL-16 powder at 38.5gr with Fed 210m primer,... last 5 shots of the day!

Wayne dominated Score with his 30 BR. Like many of us, he probably lost just a few shots that cost him a lot in the Group portion.

AS an example, I went into the last target, which was a Group target, sitting close to the top ten in Group. The mirage had got so bad that I could not see any bullet holes. The wind was around 15 mph, switching from about a 20 degree left to right to about the same right to left Very quickly. That switch was good for about 4 inches on the target.

I decided to just hold dead on and try to put five shots in what I hoped would be the same condition. I did just that. I had no ideas where the bullets hit until I went and looked through a big spotting scope When the cease fire was called.

Four shots were knotted up in about a .800 group about a line to the right of the moth ball. One shot, I have no idea which, was clear across and outside the mothball. I obviously missed something coming across that kicked that bullet out there.

That made the group a 2.235. That one shot destroyed my Group Agg.

But the final Agg did not reflect the other 24 shots. It simply showed that I screwed up royally On one shot. That’s the way Group Shooting works.

The fact that Wayne only missed the 10 ring 3 times is reflective of how well his Rifle, and he, was shooting. Remember, that was a 200 yard target at 300 meters.

So to answer your question, Yes, Wayne‘s 30 was agging well enough to win the whole thing.
I like to look “outside the box”. I am not taking away from Bart’s outstanding shooting ability and a win against some of the best shooters in the country. I know we are talking about the best cartridge/ bullet combo. But, that is not all of the equation to success. I have not heard anyone mention the scopes used! I bet Bart was using his new Valdada Precision 10-60x56 scope with 40mm tube. Jackie said he could not see bullet holes through his rifle scope, but could through his spotting scope. I had the Valdada Terminator very similar to Barts for a year or so. It was very close to looking through a spotting scope. So, maybe Bart could see bullet holes? I dont know. But, if he could, that would make way more of a difference than the cartridge/bullet combo. To win in a high stakes match like the Tack Driver everything has to be working that day in precision! The rifle, all aspects of the load tune, scope, and especially the shooter’s ability. If any one aspect is lacking at all, you will go from 1st place to mid-pack in a heartbeat.

Sam,

You are too astute! Yes my scope was a huge advantage. Getting ready for this match my buddy, Jim Chaney built a target frame that we placed at 300 meters for practice in heavy mirage, on old IBS 200 yard score targets. We knew the mirage at Orangeburg was legendary and my scope would give us the best chance to see our shots. Jim and I both doubled up on my gun not only for the scope but for the extra wind bucking ability with the 6BRA and 103gr bullets.

BTW
Jim was 6th in group after 4 targets, but got caught on the last group and shot a big one.

What attribute(s) of the scope made it better for mirage conditions?
 
I had swapped out a nightforce 42 for a 15-55 competition before this match to hedge my bets on seeing my bullet holes. I was able to see my .22 holes when I heard others on the same relay saying they couldn't see their 6mm holes.
 
I really like my NF 15x55. That said my understanding from several conversations regarding the Valdada leads me to understand that the Valdada is superior to the NF in every way.
 
Incredible Glass. 40MM tube, 1/8 clicks, variable power so I could dial it down when needed. I could see my bullet holes. It’s like a spotting scope with Crosshairs. OH Yeah it holds point of aim!

Bart
Undoubtedly a fine scope. I am kind of thinking that there is a bit more to Bart winning than that and, that others had scopes, maybe not as nice, but good enough to deal with the mirage at 300 yards. Of course, I am just speculating and invite actual knowledge regarding this point.

How did the NF Comps, March HM and Sightron SVSS ED scopes perform?
 
Now this is pure speculation but wouldn't a 6BR or BRA be the right caliber for 300 yards.
My thought would be a 115 or if made a 118 gr. bullet out of a 1:7 26" barrel would be fast enough and heavy enough to beat a lot of wind drift. Lighter recoil to help with fatigue because lets be honest a 2 day match is going to get you tired, affecting your bench manners.
I don't shoot 300 yards and for me to do so would be a 11 hour round trip drive so I don't see myself doing it any time soon, so I throw this out there for those that do shoot it regularly to think about.
If I am way off base disregard my wayward thoughts.

Now Jackie you know Wayne doesn't shoot a 30BR. His 30WW is nothing more than a warmed over 30BRX.

I also swapped out a March 48x in favor of a Nightforce 10x55 on my LV 6PPC for the Tack Driver.
The March is my normal choice on the rifle because of weight concerns.

The last two targets are the only ones I could not see my bullet holes. I got lucky on the last Score target, actually only missed the 10 ring once. That was a 8 about .010 from touching the nine ring.

I simply screwed up on the very last Group Target.

i have a 5.5-40x on a 40 mm tube...they are great...but in class shooting where weight is an issue the scope in question is a full 48 ounces..three lbs and nearly $4000....still very nice
