Hey all! Went to to the range today with some refined 225TSX loads for 338RUM, after reading the last week or so about how difficult it can be to get accuracy from the 338RUM I was quite pleased when I took a tip from someone and tried seating even deeper than I had been. The following is a 3 shot group at 100 yards, 3 other groups of the same load were nearly identical. I think I found a winner...... IV minus 300 posts from my total (for all the times I should have just kept my mouth shut......) | ||

Nifty! I just had similar results with a 168 grs TSX in an R93 in .300 Win Mag. These bullets are amazingly accurate - even more so when you consider they are pure hunting bullets! - mike ********************* The rifle is a noble weapon...

I am really jealous!!! What kind of groups were you getting before you tried seating the bullets deeper? Maybe that's my problem; I try to seat them near the lands and haven't been impressed with their accuracy. | |||

I did an experiment with my 375 H&H and the 300 grain TSX shot the best at .060" from the lands. As I moved in, the groups kept getting bigger until I got to 2+" at .020" from the lands and I stopped testing there.

I have very similar success with the TSX's in 22, 270, and 338 caliber also. What couldn't or dare say, shouldn't you hunt with that combination worldwide? I'm thinking elephant and rhino? | |||

I had been using .050, I had experimented moving forward to .030 and as others have said, they got worse. I moved back to .055 and .060 and they stayed at about .5" (which was obviously fine) this last week I decided to try deeper just for fun (even though it did not improve going from .050 to .060) and to my surprise .070 was about .5" group and then .076 the group really came together.

Another question that comes up is did your velocity drop as you seated deeper? I have noticed this before but haven't investigated it thoroughly. If your velocity dropped then the bullet was exiting the muzzle at a slightly different moment in the barrel vibration process. I'm not recommending this because I'm still investigating it myself, but you might want to run an OCW sequence around that powder loading. http://home.earthlink.net/%7Edannewberry/dannewberrysop...ightloaddevelopment/ If the velocity is the main reason your groups got smaller than a very slight reduction in charge weight might allow you to seat the bullets closer to the lands and still get similar groups. ____________________________________ There are those who would misteach us that to stick in a rut is consistency - and a virtue, and that to climb out of the rut is inconsistency - and a vice. - Mark Twain | Chinese Proverb: When someone shares something of value with you and you benefit from it, you have a moral obligation to share it with others. ___________________________________ | |||

Hmmm,,, interesting, I always go about .010 from the lands. Gotta try it. | |||

I've thought of velocity being the difference rather than seating depth. When I work up loads, I work up the powder charges incrementally so if velocity was the main factor, there should have been a charge weight that worked for me and there wasn't. | |||

That would be very good accuracy for a varmint rifle,let alone a big game rifle. | |||

Barnes always said to seat the bullets .050 from the lands for starters, and that is pretty darn close from my experience. The TSX is quickly becoming my accuracy bullet in a couple of rifles that were not particularly special in the grouping dept. The TSX is a complete different animal than the old X bullets, great accuracy and minimal fouling. It cured the problems the x's had from the start. A shot not taken is always a miss | |||

Getting ready to work up loads for a 7-08 and a .270. I'm thinkin maybe I ought to try some of these TSXs-- An old pilot, not a bold pilot, aka "the pig murdering fool" | |||

Well Ihave to say the same about the 180 gr tsx out of my 300 ultra I put 6 rounds in .435 @100 and just my luck the 6th round opend it up .308 I have to say so far I have only had one gun not shoot the TSX out of 10+ its a 6.5x55 win fwt but it doesnt shoot all that well any way. I have a 7 ultra coming cant wait to shoot it. You can't kill them setting on the couch. | |||
