Bear Creek Arsenal now posting pictures of groups at 100 yards on their website

sbowhuntr Wrote:Well I took the old bca 20" grr out this past weekend for a real test. It did well doing 3 round groups with 90g varmaggeddons and 30.7g H-335 cci 450 primers. 7/8"-1" 100y 3 shot groups were common. So about consistency, it was a no go as 5 round groups opened up to around 1.5 -2" I did one 10 shot string and it was good till the 4th shot and then fell apart, ended up with a 4" group��. Its good for hunting i suppose but I ordered a 20" monster bbl tonite.

You’re exactly spot on with testing your barrel beyond 3 shot groups .

Typically my standard are 5 shot groups when determining a barrel/rifle accuracy capability.

I’ve recently also been testing “hog hunting shooting simulations” where I shoot a string of 10 as quickly as possible (returning the point of aim to target) to see if the barrel/rifle string beyond an acceptable accuracy threshold.

All in all the Diamondback 10 shot groups stay under 2.5” and as you’ll see below a DRACOS straightjacket’ed barrel turned in a sub-MOA 10 shot continuous fire group.

Both of these barrels get the nod on hunting day !

Here is an example of what I try to recreate during the hog hunting simulated groups: hunting sounders of hogs will heat your barrel up fast - be ready by practicing this type of string of fire.

And here is a video of range testing 5 and 10 shot groups

Hi sbowhuntr,

Different resellers have different policies. You, obviously can spend your money where you want. I did keep the barrel, kind of. I trashed it after cutting it up to keep anyone from trying to use it. I am not able to measure the bore diameter accurately more that an inch or so on either end. The evidence of criss-crossing tool marks indicates to me that the barrel had not undergone final machining. I am somewhat familiar with machining practice and that is my 40 years of experience speaking.

My statement regarding BCA's lack of concern for customer safety is based on the fact that they obviously did not conduct a 100% inspection prior to delivery. Inspection of firearms barrels is not just a customer satisfaction issue, it is one of safety for the end user. Firing a barrel with an under-size bore is dangerous.

I'm sorry if you still feel my observations are BS. We are all still free to express our opinions and I respect your right.

Thank you.

Some folks don't have $600-$1000 to spend for a high quality build upper. Buy the $250.00 BCA upper and take it to a local quality gunsmith. 1 HR Bench rate $60.00 and the gunsmith can tell you if the upper is within SAAMI Specs and safe to use. That is still a lot cheaper for folks that don't have a champagne budget.
My $250.00 BCA 6.5 Grendel Upper shoots 1 MOA and that's good enough for me to shoot wild feral hogs.

I own high quality builds and in fact built an M5 Aero Precision 6.5 Creedmore myself. Cost as much as buying a complete Large Frame AR platform but I chose the parts I wanted instead of someone else choosing for me.

A Diamondback Grendel barrel costs $ 125 ... shoots better than any BCA ever tried

There is a quicker way to test without using a gunsmith first, take a Hornady Factory 123gr round, chamber it and try ejecting it without shooting it. On three BCA uppers I got the bullet gets stuck, you need to uses a tool to force the chamber open, be careful sometime the bullets stay lodged in the barrel and gunpowder everywhere. Just spend $50-$100 more for a PSA upper.

Do not disagree with you at all. My advice is for someone who is not sure of their abilities.
For reloaders make several "dummy loads" that are loaded to same bullet-cartridge length- and OAL of Factory load such as Hornady. That's what I do and that way don't have to deal with using live rounds in the test.

Put together 6.5 Grendel with 24" BARREL. I was expecting it to be a tack driver but a shotgun will shoot a closer pattern. No accuracy whatsoever with three types of ammo. Bought the upper complete from Pro2a Tactical. It has a BCA barrel on it. Where should I start? Be gentle

Get rid of the BCA barrel.

Can you be specific as to the results? What ammo, what did you do, what conditions, what results? Any pictures?

These are the questions the retailer will ask if you do the normal thing and contact them with your concerns.

Very sporadic with no consistency at all. Several shots missed target all together. It shot so poorly, random would be good word to describe accuracy. Never achieved any kind of group.

Ammo used
Hornady 123gr SST
FEDERAL FUSION 120 GR
Barnum 100gr fmj

Without details like pictures of the groups, range setup, distance and conditions, no offence but it's still just an unfounded claim. Everyone's definition of accuracy is different so it's all relative.

With only the detail in the thread so far it's less likely to be the ammo than other factors; these include the gun, the rest, the conditions and your ability to shoot. We get you are angling to blame others but there are a lot of possibilities here which you are responsible for. There's also the elephant in the room which is a low count poster abusing social media for cheap competitive gain, or a disgruntled former customer. You see where I am coming from?

Before we follow your lead and dump all over the retailer and barrel manufacturer let's see the detail so we can help you.

Check to see if the optic is mounted tight. Then check the barrel nut for the same.

Optic and mount would be my first thought.

Guys I'm not looking to dump on anybody or any retailer. Just thought you guys could shed some light. I'm 66 years old and have zeroed dozens of rifles in my lifetime and I'm never seen this before. I've been in contact with retailer and they are issuing an RMA and are replacing the barrel. Sorry to take your time.

BCA haters take note of the quote from the Pro2A tactical web page.
"BCA makes very high quality barrels. Made out of premium 416R Stainless Steel for enhanced corrosion resistance and accuracy. "
There you have it, case closed! Smile
https://pro2a-tactical.com/ar-15-upper-a...upper.html
Numerous threads on the forum on what to check on a BCA. Start with inspecting the barrel crown (take off the flash hider and test without it as well).
More info on your setup will help. For example what trigger, scope, stock, rest, distance shooting, barrel break in (total number of rounds fired), etc.

Ask away, the vile horde is a great resource and usually very helpful.

A 'Rookie' who wants us to be "gentle" is a 66yo who has zeroed "dozens of rifles". If you know your stuff and have already contacted the retailer then let us know how it all turns out because clearly you have it in hand and don't need our advice. Wait until it is all resolved before sticking the boot in. You might not be so disgruntled if they look after you...or if it turns out it's your fault.

It's a BCA barrel. What else does he need to say?

Either way, I've merged the thread appropriately. There's a great set of tests across numerous barrels with detailed results, conditions, ammunition, and control rifles in this thread so that nothing should be surprising.

Specific details mean we don't assume.

Deduction trumps abduction any day.
