PGW LRT-3 50 load development thus far

It actually works amazingly well. It was quick to put together and after braking the first piece of plywood, i went with something considerably heavier and now all is well. With a blanket over myself and the scope to stop the glare from the sun being so low while shooting south, there is also zero blast felt what so ever and the blanket doesn't even fly away. Concentrating on accuracy is greatly increased now which is nice.
That's it we are changing your name to ####-A-Maniac
You sir need to hand over your man card
You could probably install a Latte holder on your sheild I can supply some pink spray paint and sparkles You just inspired me to get my photoshop working Okay okay all joking aside great idea I was planning on making a small deflector that fits over the brake I will post pics when done. I am pretty immune to the back blast now really does not bother me much except when shooting US-869 powder you get particles of unburnt powder once in awhile peppering your face. The muzzle brake works very well and is light so it does not mess with the harmonics of your barrel so if you are making one try and keep the weight down.
One of those guys eh...!!! that love the feel of burnt powder and hot gas slapping them on the face. Nothing better first thing in the morning!! Lol
Truth be told, I don't drink coffee and I love the smell of gun powder, just not impregnated in my skin or up my nose.
I am interested to hear about how the powder you use differs from US869 since I haven't tried any other powder.
As for the brake design and weight?? I wouldn't mind sticking with something close to what is already on the gun actually with the exception of a few changes and most to do with the direction of the gases mainly. Weight wise, I want to keep the weight down also by finding cast blocks of steel. The brake is almost as light as aluminum or so it feels.

H-50 is a temp stable powder so is VT 20n-29n probably even more stable the the H-50 they also have different burn rates. I beleive brass prep to be very important for consistant accuracy in the .50 BMG I have even more tools on the way for brass prep. I already have flashole uniformer primer pocket correction tool, annealer, CH4D Neck bushing die and straight line seater die my concentricity is .0015" - .005" with the new tools I should have this consistantly under .0035" with mostly .002" and under the buulet will print in the barrel correctly with less velocity spread. Concentricity is important! I plan on making the blast defector as small as I can get away with and use 7075 alum.
H-50 is way better than 869 powder!
and my breif time playing with 20n29 shows improvement over H50
Plywood blast protection.........your missing half the fun!!!
you now need to shoot with your pants off from the ladys Tee's!
Joking.... well sort of... I will share my testing when i am doen with 20N29, I just started a new job so time is tight, no squeeking out earely to the spring.
Keep sharing your info, we will master this beauty soon!

From shooting quite a bit with the ATRS muzzle brakes on the 50s and my 338LM AI, muzzle blast is definitely something I have no interest in getting use too. LOL You guys use the face blasting powder eating experience as a conversational piece, not me, especially when you're burning through 50 ammo like I am. I'm not shooting for the thrill that's for sure. I want to become accurate with this gun and changing the muzzle brake will help me do just that and be able to offer you guys an opportunity for something new also.
How many grains of H50 BMG powder do you use behind a 650ish grain bullet btw?

I use 237.7 h50 with the mill ball or API rounds 647g'ish, shoots nice for crappy bullets.
I have been using 230 gr h50 with amax and my gun likes 231g 20n29, I will post all of my data in a bit when I am done or at least starting phase 2 of load development
Practice with That slap in the face, it will make you a better shot if you can deal with it, I understand you pain tho.
I'm just messing with you!
Happy powder smelling

I would also try 220 gr of h-50 under amax and work your way up in .5 grain increments no higher then 225 gr is what I have been told. Now since Matt has had no problems up higher I would work my way up cautiously. I have had good luck with as little as 215 g of H-50 but velocity will be lacking for the real long shots. 215 is popular with the tight chamber crowd 220, 222, 225, 228 is popular in the larger mil spec chamber crowd.
