Trailboss in rifle cartridges

I have loaded some .243 for my budies daughter, using data from IMR.

I assume you're talking about jacketed bullets in those calibres.

I use it in 416 Rigby and 450/400 for cast and "regular" bullits. Works good, what are you wondering about?

What velocities are you getting? (I assuming you're using 400 grain jacketed bullets)

I've tried TB in the 45-70 (easy to shoot, super-accurate), but have yet to try it in either the 450/400 or the .416 Rigby.
 
I have the exact opposite results of A-Zone. I have tried trailboss in my 30-30, 444 marlin, 45-70 and .44 mag and to date I can not get any accuracy out of it. I switch to IMR 3031 for the rifle cartridges and accuracy returns immediately. I mean with TB I get minute of pie plate at 100 yards and with IMR 3031 a gopher is in grave danger at 100 yards. My experience with it.
 
Have loaded it in the 7mmRM with 139 gr Hornady HPBT. Recoil and noise levels are about the same as the .223. Very accurate too, POI is about eight inches lower than full power loads at 100 Yards. Handy to have a few in your pocket for those of us that can't walk past a partridge or rabbit while hunting four-legged critters.
 
I've done up small game loads for a handful of common cartridges using TB. Not sure of long range accuracy, but just fine for small game at thirty paces.

Beats passing up fresh grouse and eggs for breakfast, I can tell you!
 
I use it with cast bullets in my 30-30 and 38-55.
It is quite accurate in my rifles, but considerably lower impact point at 100M than my jacketed, full-power loads.
Eagleye.
 
My second favorite rifle powder. I use it for cast and some jacketed projectiles in my 308, 303, and 35 whelen bullets. Very accurate in sub-sonic velocities especially lead casts. It seems 7gr is the magic weight for my rifles.
 
I shoot TB a lot in many different rifles, great for cast bullets in the milsurps, especially the mosins, I like it in the 30/06 as well, have not chrony'd a load yet but 19.5 grains behind a 180 cast gas checked bullet shoots about a 1 inch group at 100 yards and aprox 4 inches lower than my 200 grain sierra hunting load. rifle is a T3 Lite.
 
I made up some rounds for my 17FB with 5.9gr and a 20gr V-Max. Can't remember the velocity though.
 
I have never been able to develop a load in trail Boss that was the most accurate, but I use it, as it has its place for low pressure loads in high volume cartridges. It's ok for subsonic loads, but I usually go to Red Dot or Bullseye for that.

Many seem to choose it because they need their reloading to be "fool proof", i.e. it can't be double-charged, but I prefer to not be a fool, and thus expand my powder choices
 
I'm using it in my Marlin 35rem and Ruger 45/70

Don't have a chrony, but, it'll send a 180wfngc thru 2 and end up in the 3rd milk jug at 100yds
 
I've used up most of 2 cans (9 oz each) over the last couple years. Have tried it in everything from a 32-20 revolver to several different military calibers with cast bullets. Latest outing was this afternoon when I put some Lee 205 gr cast through my 8x56R carbine. Like Andy I've found it works OK but is never the most accurate. Probably a good safe place to start if you are looking for fun plinking loads for cast in military rifles.
I've used the 70% rule to work up loads when no published loads could be found. I've never tried it with jacketed bullets and do not plan on doing so.
 
This is my favorite powder for all my rifles from .17 Rem to .458 Win.
I use it with both jacketed and cast bullets and although it don't give
Olympic grade accuracy with most loads, it delivers good hunting accuracy
in all my guns. As I don't shoot big game beyond 100 yds., this stuff works
excellent for me.
The best part of using this powder is that your get much longer case life due to
the lower operating pressures. It's clean burning and even smells neat when shooting.
 
I tried it in my Ruger#1 45/70 15 grains with 350 grain cast bullets,
And for the life of me can't figure why it shoots a foot and a half high at 100 yards.
Must be velocity is so slow that recoil is sending the bullets high,that is the only thing I can think of.58 grains of Varget straightens it out!
 
Probably my favorite plinking load for my 30-30:
170gr Cast RNFP over 8gr of Trail Boss.

I just finished loading up 50 rounds of them for a total cost of $4.81... Love that part too!
