Hello All,
After much debate,"reservations"+ financial swindleing(I sold alot of unused and neglected toys),I had enough funds to buy the rifle.I paid a little bit more,but didn't have the estimated 4-6 month wait.Plus,I wanted to have it in time to work up an accurate load before an upcoming 1,000 yard match.
The rifle is a real piece of work,in a good way.Nice welds,metal fit and finish.All of the bolts are tight.After a bit of function testing and break in,It shows alot of promise.
Pros:
It's a Semi
It breaks down easy for cleaning,without any tools needed.
It's liteweight
It has hardly any recoil,for any 50bmg rifle in it's weight class.I've shot them all and built some too.
Cons:
The grip:
Too thin and it doesn't do the rifle any justice in the looks dept either.After a couple rounds fired,I replaced it with an Ergo grip from a 300 blackout AR I was testing.If you have small hands,you'll probobly be Okay with it.
The scope Base:
No MOA. A 10 or 15 Moa base would be a good addition.
All in All,I'm very happy with the rifle.I mounted my Leup/BORS combo and I'm looking foward to some real range time with it.

"I can't and won't spend $7k on a 50 bmg rifle whose accuracy capabilities are unproven"
I guess you changed your mind?

On another forum,I got in contact with a decent LR shooter that has one and said it had decent accuracy past 500yds in his hands.Hearing that it shot "Decent" at and past 500 yards,is alot better then reading it functions perfectly firing from the shoulder into a hillside.
Like you,He didn't have alot of experience loading 50bmg and he hasn't had the time to load and test any quality match reloads in it yet.He is shooting good groups past 500yds with some modified factory match ammo.That peaked my interest enough to look into the 50A again.I have alot of experience with the M82 and have modified them to make it a decent shooter at best,with single round loading.Thats 1-1/2 MOA 80% of the time.As you know,the 50A can be accurized with alot less effort than the M82,if neccesary.
It took sometime for me to get the funds scraped up and I was lucky enough to find one available,otherwise I'd be putting a thermal scope on the 300 blackout.I'll look back at my posts,usually "can't" and "won't" aren't in my vocabulary.

Well I checked my posts and found that I did post "Can't and Won't".Usually I only say that to the wife.Looking back at the post date,It was around the time my cousin and good friend were deploying again.I apoligize for the A hole attitude.

So how soon are we going to see an in-depth range report? I mean a serious one, something that goes from 100 to at least 1000 yards, group sizes, bullet types used, charges behind these rounds....
Oh yeah and LOTS of pics because you know it didn't happen if you didn't catch it on film. |

I took a half day off from work today and went to the range to do some load testing.Brought a MA deuce and a M82 also, to round out the day.I've been shooting the Amax and M33 ball loads from my M82 to break in the rifle.This time I brought the chrono and some Amax+M33 loads for the serbu.LC07 brass,CCI35 primers and various H50(Amax)+Virgin5010(M33)powder charges. After firing the first five Amax rounds that chrono'd 2450 and produced a 1.5" group at 200yds,the rest of the loads went down hill from there.I started with 225 grns and had cartridges loaded up to 235 grn charges of H50.The rim of the cases were getting ripped off with the 230 grn load and the cases were getting stuck in the chamber.I tried the rounds in the M82 and they fired and functioned without issue.I thought they were loaded too hot,but they showed no pressure signs,except for getting stuck in the chamber of the 50A.The ball rounds fired out of the M2,but not in semi mode till the hotter loads were used.
Knowing the rounds weren't too hot and they fired in other rifles,I figured it must be a case sizeing issue.After I pulled the projos,I checked the cases and found that I had used the size die for the Tac 50.I neck size only for the Tac-50.I put the semi auto die in the press and Full length sized + loaded some Amax rounds with H50 and Re50.Re50 might be too slow burning for the 26" barrel,but I'll never know till I try it.These rounds are seated .oo2" off the lands and are too long to fit in the mag for semi auto function.If these rounds are accurate,in my FPS range and eject without issue,I'll load the info into the BORS and use them for an upcoming 1,000 yd match.When I find a good load,I'll make the OAL shorter to fit in the Mag and see what happens.
The 50A's chamber is tighter than the Barrett's.The necked sized cartridges functioned in the M82,but not in the 50A.The 50A shoots more accurate with the M82's Amax match loads,than the M82.I'll update soon,but No Pics or videos till I get a target that'll be worth viewing.

| I'm only going to use Amax and 680-700 grn AP and ball projos for testing.I only shoot monolithic borerider projos in a borerider chambered barrel.Never had any luck with other types of monolithic projos in a std chambered barrel.If you want me to test monolithic projos,send me some projos,a barrel,the appropriate wrenches to change barrels(I already called and spoke to Carl.It looks like the wrenches aren't going to be seen outside of the serbu shop) and I'll do the rest. |

The A-Max bullets didn't shoot nearly as well in my gun as the Barnes TAC-X BT and TAC-LR BT.

No Wrenches??? I want a 30+" Lija one day, will have to send it back for install, Mark?
Glad you like your testing NYS, I love mine. I noticed she likes reloads much better than factory. New to reloading and loving it! Its just hard to find good 50 brass that hasnt been through hell or has goop inisde.
Enjoy:-) _________________ Kinky is using a feather

I almost don't know what to say other than "Thanks!" and let me know what you need in order to help you out. I'll be glad to send you one of these extended 25MOA rails once they get back from anodizing. Trade you for the one you've got. As far as the barrel nut, handguard nut, and barrel extension wrenches they're out for quote and we should have some for sale (or rent) within a month or so.

I'll take you up on the offer for the rail and would like to purchase a set of tools when available.I have a lilja blank ready,but want to see what the stock rifle can do first.
I went to the range sunday around dusk and had enough light to get a reading on four of the five rounds tested with the RE50 powder.They averaged 2,475-2,500 fps.The brass ejected without issue and no real pressure signs.I'd like it closer to 2,700 fps,so I loaded five more rounds with a two grain increase and will try it again.
Tony,I tested projos for some 50 cal projo manufacturers and solids performed well,but they required alot more attention and regularity in cleaning of the barrels.More attention and time than a dedicated shooter would even think about doing.Barrel life decreased with projos that had longer driving bands.Those same projos your trying.I've seen Nitride coated barrels that've only shot Moly solids Sh!t the bed before 1,200 rounds fired.They were loaded pretty hot,but we were shooting a long long ways.I don't feel solids gave that much of an accuracy increase to justify the extra work.
On the other hand, Heavy Borerider solids are a different story.Not for the 50A,but they've performed great for alot of shooters.The Amax have performed well in almost every rifle I've shot and tested.It's my goto test and LR hunting projo.I prefer copper jacketed projos in my std chambered 50's. |

Cool, a 50 Reloader. like i said, new to reloading and saw the hype about the solids. lehigh vs. Barnes? I've been using Some SA 690 gn with good to random results. Want to try something else to see the diff. Lehigh makes a Hybrid borerider standard projo, you ever use these before? Also, is WC872 that much different than H50? Been using 225gn 872 without issues for 300 yards, how does H50 work better? 872 is all the same lot.

I've tested the lehigh and other solids projos extensively.The lehigh 510-200 750 grn HP solid projo was designed for Mag fed weapons.Thunder Ammo has two solids made for mag fed weapons.The 746 grn Match82 and the 710 grn match solid.These are multi banded solids and shoot pretty accurate out of the M82.The Barnes solids have a solid drive band and will generate more velocity and pressure.Every projo manufacturer hype's their product and some do work pretty good.You'll never know until you try them and see what your rifle likes
WC872 is a powder made for the 20mm.It's a slow burning powder.It works fine in 50's,but you'll only be burning three quarters of your charge with the 872 in your 26' barrel.Good for plinking,but if you want to hunt or squeeze more accuracy out of it,your going to have to use other powders.H50 was specifically made for the 50bmg.It's not supposed to be temp sensative,but it is.Not as much as H869 or VV20n29 powder.Surplus 5010 and 860(ball powder) are faster burning and great for shorter barrelled rifles.I've been useing+ testing Reloader 50 and have been getting good results.It's also a bit temp sensative,but it's real steady in the velocity dept.In the three different loads tested today,I had less than a 5 fps variation between each of the 5 rounds fired.Thats impressive.
None of the loading programs I use have any info for gas operated semi auto 50cals,so this is new terrirtory for me and I'm working up a load in two grain increments because of that.With a 240 grn charge of Re50,I'm getting 2,600 fps and some semi primer flattening.The 242 grn loads had some rim deformation from the extractor and flat primers.My OAL is 5.600".I started with 235 grns.Those charge weight's might be a compressed load with the Amax seated deeper to the 5.450" max length to fit into the mag.I put three rounds into the same hole at 200yds and the last two opened the group up to 1".These were the first rounds I shot at a target,as it looks like 2,600 fps is all I'm going to get useing Re50 powder.I'm going to work on the trigger after the match.It has some creep,but it's a semi auto and I expected that.Once you take up the creep,it does break clean.I'm going to shoot the rifle stock for now and see what it can do. |

Steve,
The 25 MOA extended scope bases are back from anodizing. Please contact someone at the shop about getting one sent to you. You can call (813) 243-8899 or email DeAnn or Carl. Their email addresses are their first names at serbu.com
We intend to have a service where we'll do the machining on a customer's barrel blank and install a barrel extension. We'll also be putting out the specs and selling parts for the "roll your own" crowd.

Providing parts and services to allow the customer to customize the gun, is a great idea. The most successful gun designs became that way due to the supply of custom aftermarket parts. The AR-15, 10/22, 1911, etc.
It's still a bit early for the aftermarket to jump in on the BFG-50A, but it would give it a boost. OEMs usually try to avoid that....but it's a bad call.
Just ask J.D. Jones with his proprietory 300 Whisper that pretty much went nowhere, until the 300 BLK allowed everyone to jump in on the game.
Aftermarket parrts create more demand for the base gun everytime....how bout that SAIGA-12?
