Trail boss should be good in the short barrel as its a fast burning powder developed for pistols.
Any idea what velocity you were getting with 9 gr.
8gr in my 243 had a 105 gr vld about 1050 fps.
Did a number on goats. Tumbled the full length of the animal but no expansion as you would expect.
I have not gone back there as I was a little concerned about ignition on such a small charge less than 60% case full.

No idea on velocity,under speed of sound tho .will work up till I hear sonic crack,thinking 10g trail boss might still be just under sound barrier.
Went with a starting load of 30g 2206h with the 170g cast,nice 1in group @ 50m so gonna go with that for now,low recoil and not as loud as the Barnes load I usually use.just need to bowl an animal now to see how they perform.if 25g is running around 1800fps what do you think 30g of 2206h speed will be?i shot them with the 9g trail boss load into dirt @ 50m and there was very little expansion,almost could have been loaded again!
I have a mate that has bad Arthritis i load him the 135gn smk with min book charge of 2208 id have to check but 48gn from memory
Shoots well and very low recoil
+4 for the trail boss:)
You might get even better performance by taking all the casting marks off the bottom of you projectiles.
Noticed those rings in your pic.
I’m thinking that a full case(14g) of trail boss won’t get the speed I need for decent expansion,the 9.5g load didn’t expand at all.
Did you end up shooting deer with the 170s and ar2206h ?

With two grains less powder and 6 inches less barrel you would be lucky to make 1,700 fps which would be below the velocity you would need for reliable expansion with that projectile. I also chronographed the 150 grain Hornady spire point and 38 grains of AR2206H which gave 2,350 fps or about 2,200 plus in your barrel. This would likely work but the recoil may still be a bit much for your boy. A lighter or softer projectile as suggested elsewhere in this thread could be a better option. Hodgdon suggests a 125 grain BT projectile and 38 grains of H4895 (AR2206H) for about 2,400 fps in your rifle in their youth loads section.

Have settled on 110g Barnes for him,light recoil and suppressed he doesn’t mind it to much.seems to kill like a .243 at bush ranges.
Next option is I will go with a bullet ment for 30-30 and use it in the .308 with 35-40g of 2206h.
Got sme Sierra 125g 30-30 bullets today,gonna try 36g 2206h an see how they go,if no good I willl use them for subsonics small game loads.
Fail..they don’t feed well in my A7, too short I reckon,had the same problem with the 151g cast bullets in the past thought these might be better but no dice,in for sale section now.
