[averh2o]

was that 46.5 gr of varget?

Have not played enough with H4895 to give it a fair shake. Never ran XBR8208 in a Palma rifle. Some how I get just enough Varget.... right when I need it, so I keep on using it. Keeps everyone on the Team the same that way.

Russ,
Got some 175's to test hopefully this weekend at Lejeune. Unfortunately only 600 yds. but if they shoot well there they ought to shoot at 1,000. Using 4320 powder.

Shot the new bullets at Lejeune this weekend and they shot pretty good, great elevation but about a minute lower than the 155's at 600 yds.. The hotter load seemed to shoot a little better so I'll load up some different loads and head to the 200 yard line to see how they work with some better load development. Might just make a good 1,000 yard bullet.

Looking forward to seeing your results. I loaded up another 22 and shot a Mid Range prone match Sat. They shot pretty well. Trying to figure out how to get some to California for testing while im out there.

Russ:

Great pic, OK Weber has them in stock, but only 500 packs. Was thinking of ordering to try some. Will wait until people like you take them for a test drive. Heard Bob Mead shot them at AZ. They definately have a different profile from anything Sierra has ever done. I hope they are not sensitive to seating depth like all the other Sierras, or Berger 155.5 for that matter. Glad we have competition and Berger/Sierra keep trying to improve.

Keep us posted on your findings.

Tried them in my tikka t3 ctr 308....@ coal spec, .227 off the lands ...holy batshit man, 41.5 gr imr 4064...and yes they shot like crap. How can you keep enough bearing surface in the neck and even get close to acceptable jump?

I've had good luck with the 160gr 7mm versions in my 7x64 (Think 280 Rem)

I also get great results with the 160 grain 7MM's and the 175 30's.I've tested them pretty hard in my 280AI,and they're some great 1,000 yard bullets.Had I known they would be as scarce as they are now,I'd have bought more and tested less.My 280AI has a Shilen Select Match heavy barrel and it's been under .250 several times for 5 shots at 100.Best group was a .194.Thousand yard groups were around 8-12 inches summer before last,and they were shot in not the best and not the worst conditions.I was jumping them .010,but they didn't seem to care about the seating depth too much.

If only they made a 175-180gr 7mm TMK...

The throats on the guns that the original posters are shooting them in are typically way shorter than what a Tikka factory gun is. Probably a 95 Palma or 2011 Fullbore or some chamber like that. Also, you may try more powder, like 44ish grains of 4064. Work up to it, of course, but those 155s like a little more speed than a 168 or 175, at least in my experience, for whatever that’s worth…..

Thank you sir...much appreciated. Only tried the low charge because I had no idea what that bullet would do with that amount of jump.
