New Barnes LRX - Help Needed

(1/3) > >>

engelwood:
Alright, so I got excited about the new Barnes LRX bullets as they are Barnes first off (generally shoot great out of my gun) and because they are copper solids, which wreak havoc on animals. I purchased a box of Barnes LRX 175 gr. bullets for my 300 WSM and loaded up a few test loads. I am using Alliant Reloader 17 for Short Magnums and have had great speeds and accuracy with other loads I have made up recently. Long story short, I made up three (3) shot loads and tested the groupings. Speed was not an issue as I figured, but the accuracy of the bullet was not what I would consider acceptable at 100 yards (we are talking 2-3" groups). I'm shooting the TSX at under 1" consistently. The LRX is appealing as it has a high B.C. at .504 as compared to the TSX which is in the low .400's. Question is this, does anyone know any tricks to making up this bullet load to make it more accurate? Does anyone have any ideas on what I can do to increase accuracy? (ie. back it off more from the lands, etc.) I am loading at the maximum coal of 2.86" which has not been an issue in the past as I mentioned for accuracy. Would speeding it up help? Anything helps. I'm shooting a Remington 700 XCR 300WSM with a Leupold VX III 6.5-20 x 50. Thanks for the help!

BULLBLASTER:
Just need to play with things some. Try different powder charges and different lengths. Its amazing what as little as half grain powder charge will do. I like the x bullets but there are better choices for what I am looking to do. Wouldn't mind trying some 200good grain lrx. In my rum though. Good luck.

Caretaker:
I don't have any experience with that caliber but I do with the 270WSM and 300WSM.  Start by making two groups of the same loads starting with a few grains below the max in .3 gr increments.  Once you find the groupings where the sweet spot is load some more with .1 gr difference.  Also, use a COAL gauge for your specific rifle.  You may want to try different primers such as the Federal's and CCI with the same loads just different primers.  You will be surprised at the difference results.

sirmissalot:
You might try a different powder as well. I was having the same problem with the Barnes ttsx in my weatherby, called Barnes and they suggested trying reloader 19. Amazing the difference it made.

bobcat:
I would try H4350.
