Most Popular Chamberings for LG & HG @ 1,000yds

[Rat Rifle]

For those who are keeping track, what is the answer for the most consistent winners this past season? I probably already know but I would like to confirm it from those with the most knowledge on the subject.

Thanks...RR

For NBRSA on the West Coast, the 6BRA dominates in both LG and HG. That said, Heavy Guns in 300WSM are starting to show up more.

 

[Jason Boersma]

Bra and Dasher most popular then 300 WSM and some 6.5’s

This question has been answered dozens of times. Dasher, BR-AI, BRDX, BR, give any one of the top shooters any of those cartridges and they will still be at the top of the list.

what is the difference in light gun and heavy gun?

what is the difference in light gun and heavy gun?

LG is limited to 17 pounds (600 & 1000 yard)
HG has no weight restrictions and I believe that any width forend is allowed. (600 & 1000 yard)
The IBS & NBRSA Have a rules (on-line at their web-sites) section that go into very detailed explanations of what is allowable for all the classes and varying competition disiplines.

Actually....there are no stock width restrictions on LG either in IBS, Penn, and, if I am not mistaken...NBSRA.

I shoot at Williamsport and the 2 most common are the 6mm dasher and 300 wsm.

At Williamsport the two Dominant cartridges are 300 WSM and Dasher. The WSM would probably be the most dominate except some cant handle the recoil in a 17 pound gun. They are followed in popularity by the 6.5x47. The top 10 in aggregates are pretty dominated by the first two. Matt

.....or when then wind is light take off the 300 WSM barrel and put your 6BRA barrel on your HG.

I don't think "not handle the recoil" is the right way to say it. I have both 300 WSM and 6 BRA barrels in my LG. At 600 yds the 300 just couldn't be shot fast enough to stay in the same condition. While it shot very consistently, it was well behind all the 6 BRAs in the relay. I did win for score.

It would do much better at 1000 vs the 6mms but with COVID messing things up I didn't get to see. My first 300 WSM LG shot well at 1000 at a range that had mostly mediocre conditions. After I moved away, all my records were beat a 6mm.

This issue with an LG 300 WSM it it moves back under recoil about four times as much as a 6mm. It takes a LOT of BC to overcome a slow shot string.

In an HG 300 WSM everything changes. The rifle can be made heavy enough to shoot as quickly as the 6mms. At 600 yds a fellow competitor did as well as any of the 6mms in HG. He also did well at the Nationals at 1000 with his 300 WSM, so much so that several competitors are now building 300 WSM HGs.

In 6mm they work as well as a HG in the HG class. 17 lb 6mms beat much heavier HGs all the time. However, since I was building a 300 WSM already, all I needed was another bolt and the chamber another barrel so I can go both ways.

I shy away from the 300 WSM, due to eye problems .... Light or no recoil is better...... jim

My beloved Nightforce BR 12-42s didn't have enough eye relief for a 17 lb 300 WSM. The Vortex Golden Eagle has an inch more eye relief, and kept the rifle from hitting my glasses on recoil.

ya, when they have rubber around them, it is telling you .... you are going to bleed...... jim

Been wondering why you don't hear of 7mm/.284's in the mix.
Since I started experimenting / altering cases in the .284 area,
bullets have been a slight draw back. Would yinz say this is
the problem ?? In F-class the .284 Is a staple on the table,
but not so in BR. Any insight ??
