Hey guys tonight I am loading .308 with 4064 and 180 grain Barnes ttsx bullets. The bullets are so long that my starting load at 41 grains is being compressed. Can anyone tell me if this is alright or because of the bullet length should I back off some more?
 
I don't know where the idea originated that one must use Barnes data only for Barnes bullets............hogwash !! With the cut ridges now, the Barnes bullets present no greater frictional coefficient than any other bullet of the same weight. I have proven this out at least 50 different times with different weight Barnes bullets and different calibers. In fact in some cases the actually prove to be slightly slipperier than a regular jacketed bullet.

OP don't worry about compressed loads, I actually look for powders that will compress when working up loads as I find them to be more consistent and have a lower SD than loose powder loads. And in a lot of cases be more accurate.

Thank you c-fbmi ! this is sort of the info that I began with but the length of the bullet was off putting. I wasn't worried about compressing powder,just that I was doing it on my min load.
 
I load these bullets in my 30-06 with 46gr of 4064. You gotta remember how long they are aswell, a 180gr TTSX is longer than a 200gr SMK. So it's easy for it to take up the powder space..
 
Also, 42gr of 4064 is the minimum starting load for a 165gr TTSX so I would assume that your start of 41gr is going to be to high for a 180gr TTSX

If 42 grns is starting for a 165, then it makes perfect sense that 41 grns should be starting for 180. There is usually only a grain or two difference between the loads for these 2 bullet weights in 30 cal.

Yea your probably right, you got much more experience than I do.
 
Solid copper bullets don't fly like lead cored bullets. That's why you need Barnes data. It has nothing to do with how slippery a bullet is or is not. Or frictional anything.
And to get the weight the bullet has to be longer due to the difference in mass.
Compressed load are definitely nothing to worry about though.
 
Sunray, you never cease to amaze..................have you ever actually even fired a homogenous bullet? Oh ya I forgot, you never stick around to answer questions, you just dazzle us with your profound lack of firearms knowledge and then evaporate until tomorrow.
 
My first experience with Barnes mono-metal bullets was with .416/350 gr Xs, several years before the TSX became available to the public. Every box was a surprise because the tips were never the same size, one box were like the hollow points on match bullets and the next were as big as an ashtray. When I worked up the maximum X Bullet load for my Rigby, I discovered that it was exactly the same as the maximum load for the Speer .416/350 gr Mag-Tip, 102 grs of H-4350. That was before the banded TSX, which in theory reduces pressure.
