6 BR recommendations

[Beck]

I know this horse has been beat to death. Im wanting to build a 6 br. I'm thinking about a 7 twist and shooting 95 - 105. The main distance I'll be shooting is 300 yards. Give me the ups and downs on this combo. Or what you would recommend for 300.

 

[Phil]

A 7 twist is a little much, if 300 is truly your max then pick a good mid range bullet and build to it.

What is the rifles purpose, that makes a big difference.

They shoot the IBS 300 score target. But there's a twist. Instead of 1 shot at each, they shoot 3 for a total of 150 points 5 x. I know most shoot the 30br at tips range but I like the heavier bullets (95-105) for their BC. I'm leaning towards the 105.

Would the 7 twist be to fast?

 

[Phil]

You need some info from others shooting 300 yards.

I only shoot the 103-108r. bullets past 700 ish....

At 300 i`m still shooting the 39-88gr. bullets, but i`m a varmint shooter, so i tend to do things differently.

My 6 BRDX shoots the 65gr. Vmax like a hammer out to 500+.

Personally i`d look into the 6BR with the 88 Berger at 300 yards, 10 twist barrel.

Everyone I know is shooting a 1:8 twist for this.

Yeah I don't really see a need for an 7 twist. Heck if 300 yards is the max then there is no reason for the 105's either. Shoot a match grade 70-90 grain bullet out of a 10 twist.... Done deal

i have two BRs that i shoot 105s in. They are both 8 twist and perform great from 100-1000. I wouldnt get really worked up about trying some new combination, i believe the regular ole br with a berger 105, and some varget is a hard combo to beat.

......snip....... i believe the regular ole br with a berger 105, and some varget is a hard combo to beat.

I'm a 1:8 twist guy too, mostly 600 yd F Class using Berger 105s of various flavors, but I prefer IMR 4895 or Vihtavuori N-140 over Varget 'cause I can't find Varget.

The 1 in 8 seems to work good for me, this was a 5 shot group at 55yds with 90 gr. The 105gr. shot just as good. Shooting off bipod on my porch.

At 300 yards, the 95 VLD grain should buck the wind slightly better than a 105 Hybrid.

I'm with the others....1:8 is the twist you want for the stated purpose, especially if you decide to go longer or shorter range later. Obviously shorter range means a lighter bullet as well. And a custom build ain't cheap so better get it right from the git go. Just my .02 worth.

As you say, "custom build" equals expensive, or at least it can be. But it doesn't have to be if you do it yourself. I recently bought a used-but-never-fired Savage 12 LRP. I sold the new barrel and stock and recovered all but $300 of my initial investment. I was left with a repeater version of the Savage Target action and target Accutrigger. I put on a 6mm BR Norma Shilen Match Select Barrel and bedded the result into a Boyd's Pro Varmint stock to shoot F Class. I even found a second hand, but never mounted scope worth $1500; I paid less than a grand. Add in a scope base, some rings, some Devcon 10110 bedding compound and a few nuts and bolts and the total cost is still below $2000 including the good glass.

You might not take this equipment to a world championship event without expecting some of those "stink-eye" looks from your fellow competitors, but this sub $2000 gear wins (sometimes) where I shoot. Accuracy is expensive, but it doesn't have to be REAL expensive.

I have a 6br in 7 twist. It will shoot 107's very well and it's won some group matches, and a couple of varmint matches at 300yds. It is not as competitive with the 105's as they seem finicky to tune in properly (at least for me they are).

During the great bullet, powder and brass shortage of a couple of years ago, I tried to get it to shoot the 95's from 3 different manufacturers. It would shoot them well at 100, fair at 200, and not worth a hoot at 300. That has been my experience, your mileage may vary. WD

 

[Beck]

Thanks for the info guys. It looks like a 8 twist it is.

I've got a different take. If all you plan on shooting is 300 yard matches, then forget the fast twist stuff. Get yourself a 13.5 or 14 twist 6mm barrel, chamber it in 6PPC, and shoot custom short range bullets. Learn to tune that rifle, and you'll be far ahead of the VLD bullets. IMO, long range bullets and barrels should be use at long range, not 300 yards. I've shot matches at 100, 200, 300, 400, 600....group, score, group and score, etc. Much testing of VLD style bullets at 300, along with shooting lots of short range BR at 300 told me one thing. A well tuned PPC will out agg anything at 300, day in, day out...

Run the ballistics on the 95, 105-107 and 62-68 grain bullets at their respective velocities. At 300 yards the 95 and 105-107 range bullets have almost identical wind drift in a 10mph wind of just under 6" with the heavies having a slight edge, while the light point blank bullets have about 12". If your great at wind calls the point blank bullets might agg great but miss a wind call and you'll get your arse handed to you real fast.

I know what the ballistics programs say, but they fail to take tune into account. A tuned rifle bucks the wind far better than an untuned rifle, and therin lies the advantage of the short range bullets. What I'm saying is that the long range bullets don't come into their own until past 300. I've seen a few shooters chase this mystical 300 yard combo that just has to be better because the charts say so...they'd fair far better if they could just keep their PPC or 30BR shooting all day.

 

[GSRswapandslow]

if you know most people are shooting a 30br.............then why are you trying to reinvent the wheel? See what wins at your range....there's a reason people are using what they use, and it's not because the internet told them too (well...sometimes its not...)

Yep^^

There's an evolution to this hobby. I've been shooting local matches for about three years now and I don't feel ready for a PPC yet. I may get there eventually, but there's a lot of appeal to us newbies in ready to roll calibers like the 6br, 6.5x47, Creedmore, etc. Load and go. Spend more time shooting in match conditions and practicing and less time fiddling. I'm not arguing whether or not a well tuned PPC in the hands of a good shooter would group tighter. I think that's pretty well proven to be true. I just don't think it's a recipe for success for someone just getting started.

The guys that win matches that I shoot in are shooting mostly 6br, 6 dasher, 6.5x47, 6.5-284 and .284 win/ shehane. These are 200 - 550 yd "break stuff" matches with no sighters after the first relay. Some matches, your misses are blind (lonely feeling). No agg or score shooting, just knowing where to hold and keeping a consistent POI over 4-5 relays in 3-5 hours. A few 30BRs and 6PPCs may place sometimes, but not often. I don't ever remember one winning. I don't completely understand the OP's match format, so i don't know if it is similar to ours or more like a traditional score/ group match. Regardless, my $.02 to the OP is to go with an 8 twist 6BR shooting the 103gr to 108gr pills. It can win from 200 to 600 and the learning curve isn't quite so steep when you have ballistics, proven components and well documented load recipes all working for you. You'll learn what you want to try next in the 2,000+ rounds that the barrel will last you. Don't be surprised if it's another one just like it.
