Aw man that popcorn analogy is probably the best and most original way I’ve ever hear someone describe the density of Trail Boss compared to almost all other powders.
I use 11g Trail Boss under a 220 or 225 g Hornady projectile. Not sure of velocity but would be around 1000ft/sec give or take. I zero my rifle with supersonic 180g rounds at 100m then use the ballistic reticle to hold over for 100m targets subsonic. 1MOA is doable sometimes 4 shots out of 5. Big projectiles need a 1;10 twist or faster. If you use the 2.8 inch max length for the overall cartridge and a 225 Match projectile then 11 grains is getting very close to the max non compressed capacity of the 308 brass. Word is dont compress the Trail Boss Powder as very bad things can happen. My next task is to track down a good 220g projectile that will mushroom on deer because match stuff and probably sst or other ballistic tip stuff wont.
speed of sound changed depending on altitude etc. my 308 takes about 9gr trail boss for ideal velocity of about 1050fps with a 150gr cast projectile. i tend to favor increasing the weight of the projectile, over reducing the powder charge. I have now gone up to a 200gr cast projectiles, since i have a 1/10 twist and yet to tune the powder. i have heard a lot of people talk about projectiles stopping in the barrel, however, yet to see it in real life when you are driving the projectiles at 700-1050fps.
The Armed Tramper, Use not just subsonic bullets but put petroleum jelly in the sound suppressor and hear the difference. About the only thing that you'll hear is the snap of the firing pin snapping forward.
Hi Nathan. I'm using the Winchester subsonic factory loads in my Tikka T3 and they are firing clean, I've sighted at 50m and am grouping in 1inch. Are you shooting further than 50m? Do you know what your drop at 100m is?
Ahh found pt1. That gives me the info on the rounds I was looking for. A couple of questions....do you use a filler in the cases to take up excess volume?.Or does the trail boss eliminate the need for this as its such big particles?. I've seen videos of people using the stuffing out of soft toys for a filler?. As the trail boss is large how does it throw?. Also what barrel length and twist rate are you using in your rifle?. Many thanks for the info.
16” barrel - can’t remember twist off hand, but have answered that question before so it’s in the comments here somewhere. Trail boss fills it nicely, not too loose, seems to burn well and fully. Throws fine through my hornady autocharge
@@TheArmedTramperNZ well i cast my bullets verry soft they expand prety nice. Does not matter where I hit them. My bullets are so soft you can pinch em with your fingernail and leave a visible indent. But its hard to get then to shoot well when they are so soft. Need slow powders for keeping pressures low. Next attempt i will mak bullets with a softer nose and harder shank.
Really cool work! I have to say I’m surprised how loud it still is! Is that because it is such a light gun? There is some other videos out there with just a plopp-pling Sound. Anybody please enlighten me!
The Armed Tramper that’s awesome thanks for that, we fired out first today used 10gr and slightly fast at 1168fps. So we are now just going to slowly reduce it. We are using the 168gr Lehigh bullets. Really enjoyed the RU-vid video so well done really inspired us to get to it
Hi. Not sure if you'll get this. I've watched all your video's . I have a bergara takedown and want to load sub sonic rounds. I have 220gr hornady sub x . What would your suggestions be? I have primers ,still trying to source trailboss powder. Hope to hear from you. Regards Robin
Thanks man. You don’t happen to know the sellers username do you? Iv been watching tm for a while now and have only managed to get hold of 151grn bullets but i would prefer something closer to 200grm too.
Not sure what you’re on about chap. First of all, that’s 50 metres. Secondly the group is INSIDE 3 MOA. That was the goal 1 1/2 inches or smaller at 50m - that’s head shots all day.
can’t get close enough to the wild pigs and bucks on my ranch with sub sonic 308…..they are worthless to me, however, 308 147gr hot loads…no problem shooting 0.0125 groups at 200yds zeroing
Wooa... Man with brains... One of it's kind... Using very reliable budget rifle with internal hammer 👏👏👏👌👌👌👍👍👍 Scum with external hammer is for brainless creatures !!! Excellent video mate. LIKE 👍👍👍
