Find the lands (jam point) in semi automatic

Ok,…… we have all tried to tell you it’s a hunting rifle and nothing more!…. It’s not a piece of crap!… it’s a Browning!…. John Browning made the best guns in the world however you can’t compare a $800 hunting rifle with a $6000-$10000 fully custom br rifle. Now with that said what scope and mounting system do you have on that rifle?…mounts? And whatnot?. You have been getting it hot with those five shot groups do you have a carbon ring starting?… have you looked in the bore with a scope?… is it copper fouled?… is the rifling sharp? What does your crown look like?….. what setup do you have for shooting?… solid bench,…. I mean solid!… sand bags? Bipod?.. shooting rest?.. rear support?.. my M1 Garand shoots between 3/4 and 1” it might do better if I rung it out more but it’s plenty good for what I use it for and it will easily hit my 600 yard gong are all your screws tight and correctly tight?… there’s a lot to this sport AbeS we’re all here to help ya but you can’t pull a loaded 24’ stock trailer with a corvette and you can’t beat the corvette up a windy grade with a dually dodge pickup . Let’s get this BAR shooting somewhere in the 1moa range and if you want to shoot smaller groups with a hunting rig build one from the ground up and it will shoot those 1/2 Moa groups your looking for

I appreciate your comment. I apologize for my rant. I have Leupold vx5hd leupold mounts. I shoot laying down off a Harris bipod and and rear bag the barrel crown is fine, after barrel break in its fired only 68 shots I did not think that copper fouling or a carbon ring would be an issue this soon so i have not checked. I got this as a gift brand new in the box it’s the latest mk3. The rifle cycles perfect not one feeding jam or ejection issue

This is two shots at 100 I could not find the third shot ( I only loaded three shots groups for seating depth nodes because traveling home and to farm takes time) the group printed low it’s more likely that it placed under target rather than in the same hole as the other two. At 500 i shot at a big (and I mean big) fresh painted gong but that was all over the gong not a group. Not lateral line or vertical stringing just random all over. I did not have any more reloads to go back to 100 And not enough time drive back home reload and drive back to the farm. I have a 550 yards range I admit that I choose wind still days like today when shooting out that far. my experience competitively long range is not much I do shoot a lot out to 550 so I practice a lot but then again I choose my days when the wind is favorable

Flatten that group out I bet you find the third shot

Actually 68 rounds through a rough factory barrel could be very fouled. The triggers in those rifles suck!… I did find a aftermarket trigger for my ex wife’s 708 browning xbolt that worked nicely, I can ask my smith what it was it even had the gold trigger. I’m sorry I kinda jumped on you RegionRat is correct don’t get discouraged. I’m not lying when I tell you I was in your shoes at one time in my life. I spent a lot of money trying to get benchrest accuracy out of factory rifles!… I still go much further than I should although I rarely buy factory rifles. I have one of those scopes there nice scopes although I find it difficult to get parallax adjusted just right. Make sure your taking the time to adjust it correctly it really can screw up your groups. I think your rifle will shoot for ya if you can be satisfied with maybe 1 moa who knows it may do better. If you didn’t have wind and your confident in your shooting abilities and your setup I really would look at scope adjustments
Best of luck my friend and you got this!…. It’s a fun sport,…. Don’t make it a job

That looks like 3 to me. Listen if you want to shoot long range with a factory rifle a BAR ain't it. Sell it buy a bolt gun with a heavy barrel and get to working up a load. Oh and I've seen a ton of groups from BARs and that is the smallest I've ever seen

Thanks I’m taking every bit of good advice I can. I really want to like this rifle I’m hunting in Africa end of this year and shooting springbuck and impala at 400 is common practice over there. I was really hoping to take this rifle. I’ll be back out there tomorrow I’m hoping for a better day. Thanks again

Absolutely and you will get it.

You might be better served by practicing rapid bolt manipulation with a more accurate rifle. I wouldn’t go on a hunt like that with a “spray and pray” rifle.

Yep I tried today again. Called and got the receipt. Will be taking this rifle back to scheels tomorrow

Got a seekins precision 6mm creedmoor because they had the nosler brass for it and I can use the h4350 I have on hand

 

[DiffEQ]

Many years ago, I tried finding the lands depth on my AR10. Long story, face full of hot gas, etc.
Recommend you find the shortest, most accurate round for your AR and load from that. You can get MOA or better accuracy doing that, and magazine length won't matter.
In the process, learned that function matters, and for repeatable, sub MOA accuracy, I use bolt guns.

Glen makes nice rifles! His business is only a couple miles from my town house in Lewiston Idaho. My good friend bought one in 6.5 creedmoor for a antelope hunt last November, I don’t like light rifles and it’s extremely light but it shot the factory Hornady nicely and Jay doesn’t reload one shot took his antelope in Wyoming. Again there a hunting rifle not a br rifle but they do shoot well. If I were you and I’m not but if I were I would not use nosler or Hornady brass I would buy Lapua or Peterson if your looking for the most precision you can get. Nosler is a crap shoot it’s real good or junk! I don’t know what twist rate Glen puts in those but if it’s 1:8. You can stabilize burger 115’s I have 2 6 creeds one factory Savage the other a custom by PBG out of Grangeville Idaho , I took the custom on my antelope hunt and the 115 took it right down. Hope you have better luck with this new rifle

H4350 is great in the 6 so is RL 16 I however use RL 26 as I can get considerably more speed out of the 115’s

I couldn’t find any lapua brass and lapua uses the small rifle primers and I just stocked up on the federal large rifle match primers but yes I can see what you mean I use lapua in my .222 Sako

I got 100 of the hornady 6mm 110 a-tip match @ $80 G1 bc .604 recommended twist rate for them according to hornady is 1:7.7 and yes glen seekins rifle is 1:8 twist do you think these bullets will work?

That BAR would have been just fine in Africa, just like on Guadalcanal, as long as you saw the whites (or glints) of their eyes before snatching the trigger.

Yes I think so if you can get enough speed. Peterson and Alpha makes lg rifle primer brass for the creed or you can neck down 6.5 creed Lapua brass but you will still be happy with what you have. You might have a excellent lot from nosler
