[Dusty Stevens]

Have you emailed sierra and hodgdon? Maybe varget is such a bad choice they dont list it?

 

[Evlshnngns]

Nosler has some info posted for 77-80, nothing for varget. My 8 twist 22-250 gets here tomorrow, should be fun.

Word
Reckon you wanna be a step slower in burn rate (~ '4350 range) to push that pill...

After trying several 70-80g bullets, The best load I found for my 22-250 28” Shilen 1:8” barrel is the 80g Berger VLD over 34.5 g H4350, 9 1/2 primer, 0.010” off touch. Lapua brass.

It’s an honest 1/4 minute load, lots of 5 shot 100 yd groups in the low 2’s and 200yd groups are smaller MOA than 100 yd groups. I shoot several heavy bench guns and never saw groups get smaller in MOA at 200 than 100. I’ve read the explanation is the long VLD bullets take longer to stabilize.

I had extremely good results from 33 to 33.6gr R15 behind the 75gr Amax. Varget has similar burn rate so I would expect similar results. Warm load so work up to it.

Only load I've tried has been with R19 and the ncc 77 gr. And they shot good. Got to try more, this was the first load that I've shot in it. Nosler book load.

I may have to get rl19 or h4350

H4350 is the winner in mine at this point. I've got a 7T barrel and it's the go-to for 77SMK or 88 ELDM.

How about some good loads with h4350 with the Sierra 77&80 hpbt,give me something to go by

28 inch X-caliber 8 twist, 80 grain SMK jumping .020, H4350 (work it up) Lapua brass, BR-2. Very good to 800 yds, a bit inconsistent at 1000, but I'm not a competitor and it could just be me.

I have a 9tw that has an affinity for H380 and 760. H4350 ought be the cat's meow. After theorizing how good the fast twist 22-250 would be, it still can't hold a candle to the 6mm Rem for long range hunting.

I'm setting on 36.5 H4350 in Lapua brass with the 77SMK.
