6BR bullet question

[Gumby26]

Hi all,..I have a Savage sm shank Shilen ratchet in a 1:8 twist barrel in 6BR. I'm happy w the overall accuracy but of course, always looking for a tad more. The rifle likes 105 Berger Hybrid Targets but favors Berger 108 Boat Tail Target under 30.0 of Varget, .005 in the lands. All the local ranges here in NY are 200yds w a few private ranges out to 1100yds. I would assume I should" try a custom bullet in a similar grain to see if there is more accuracy ? Does anyone have a similar rifle/load that shoots better with a custom over a mass produced bullet ? Thanks in advance

Just my opinion…. 105 hybrids and 108 BT’s are going to be hard to beat. I’ve shot some custom bullets and still do but also like the aforementioned along with the 109hybrids. It’ll be hard to shoot the difference unless you’ve got the other 99 variables right if comparing on paper.

Try some lighter bullets for those yardages. Forget what you read about "ideal twist rates" and just try some 68-80 gr bullets for out to 300 or so and some mid weight, say 87-95s for out to 600 or so. Just do it. Plenty of data on here

Thank you for the replies fella's

I wouldn’t bother with custom bullets. Like others have said the 105 and 108 are tough to beat! Even at 200 you might have a hard time finding something better in an 8” twist. You can sort them and they’ll run right along with the best custom bullets. Sorted 107 Sierra’s too for that matter.

My 6mm CM loves the Sierra 95 TMK but I haven't seem them for some 4 years now. You might try the Sierra 95 HPBT as well as the Berger 95.

What is the overall accuracy you are getting now?

 

[Gumby26]

Occasionally 3/8" to 1" groups at 200 yds. I was just curious if this is on par for this rifle/cartridge ? PS I've had better days and also worse

 

[Liven The Dream]

As stated . 105 HB are great .
Shot then at 300 F/Class Target for the first time last year 200-14 and 200-12 think they work just fine .

Wind flags are truly the most important tool you can have when it comes to real accuracy and/or precision. There are really very few cases of what some call, "no wind" conditions. That bullet(any) feels every bit of it. We all have good days and bad days but you'll have a lot fewer bad ones with some sort of flags out. Do you use flags yet?

You may be happy with less but the adage and standard for br accuracy at 200 is to consistently keep 5 shot groups in the .3's. Not MOA. Sounds like your gun shoots pretty well and I'd bet you have a lot less 1 inch groups even if you just put out about 4 or 5 streamers on coat hangers, if nothing else.

I literally made 3 last week for my rimfire matches. I’ll use these too at my center fire matches too. I’m in. Thank you

Has the #1537 95grain match king been known to be accurate?

I think your doing fine now, .5 moa or better is what i usually call good for the distance the load is for (f-class anyway).

I've no personal experience with that one, but I would think so. Matchkings are good across the board IMO.

The reason I asked was because the 140 grain 6.5 version doesn’t get near the praise as the 142 does.

That's part of the YMMV equation. Different folks do different strokes. But Matchkings have won everything there is to win except for smallbore and air rifle.

here is a prime example. shot three in one hole, then the one at 10:00 or so. no more than said 'wth', looked up from the scope and the streamer was standing out at 09:00. my condition was 06:30 or 07:00. this with good bullets at 100 yds in 6br. so....

Now you know wind doesn't move a bullet at 100 yards like that! Lol!

it can't 'always' be 'all' me 'all' the time. hahaha. bc is about 0.26. my ballistic calc returns 0.27" for 3 mph 90* (of course, assumes wind is constant for the entire 100 yards) ?

Ammerman makes good bullets. I'd try some 68s at those yardages. His bullets are cheaper than bergers. I feel your pain about the ranges in NY. It sucks.
