Yep, when Barnes don't shoot, increase the jump.

Sometimes the extra jump works miricles.

Looks like I'll be trying it. Had some interesting velocity results tonight. Accuracy isn't fantastic.

Mine shoots 120 TTSX and 120 E-Tips more accurate than 127 LRX.

Adjusted 3moa down after first group. And sorry for hijacking your thread, but I guess it is relevant. I'll likely be looking for a velocity bump and definitely better accuracy. Before I switch bullets I'd like to experiment with powders.

Very cool. I could be in for some of the N570 for my 264 Win.

DF, I would not sweat that 130 Scirroco one bit at 3400, you may get it to turn inside out and umbrella over the base but it'll hang together and retain a very good frontal area. I LOVE them to be honest. Consistently wider expansion than an Accubond.

Going to have to hit QL up and see what it shows for N570.. bet it is good. Seems about the same as RL33.

They like to jump. The 100's in my 25-06 are .125 off and really came around with the jump. Maybe more than a mono.

Increased the charge a .5 grain to get the speed back up after shortening them and shot this one.

Those were one shot readings over the Magnetospeed.

Just worked up a load for my buddy's newly barreled .270 Wby. With 7828 no problem pushing 130 NAB's at 3,400, no pressure issues and sub MOA.

Burning a lot more powder in the 26 Nosler, pushing 130's at 3,400.

I know, better B.C.'s with the 6.5, much better bullet selection. For LR target shooters and hunters, that may make a difference. For hunters shooting out to 500 or so, probably not.

Sorta took the wind out of my sails.

It's all relative. Both are flatliners.

For the hunter ain't much you want for with a 130 at 3400 in either.

My little 270 WSM will put 130's down range in a hurry as well. For me there isn't much difference in any of them under 600.

That's pretty wicked. What sorta case life do you get at 3400?

The 270wby and wsm seem to be a much better way to get a 130 class bullet cruising.

The .264 is the only cartridge that RL-33 has worked well in for me

Seems to be an ideal match for that round.

Not as good, IME, in the 26 Nosler.

I'm still working with n-570, US869 and WC872.

Still working with the 26 Nos.

The 140 NAB over 85 gr. WC872 shot .4" at 3,214 fps.

The 140 VLD over 88.5 gr. WC872 shot .56", didn't get speed, probably 3,250 or so. 3,100 is reportedly the design ceiling for Hunting VLD's, so I don't use them for hunting.

The 139 Scenar shot half inch over 79 gr. n-570 at 3,316, SD 32.

The 127 LRX over 91 gr. US869 shot over an inch at 3,446 fps., no signs of pressure. I've not gotten stellar accuracy from that bullet, may need to jump it more, adjust the load.

130 SSII over 80 gr. n-570 shot a fairly good group at around 3,400, but had hard bolt lift. The SSII has a very long shank, probably too much friction for that load.

120 gr. Swift A-Frame over 80 gr. n-570 shot an inch or better at 3,565. Good speed, average accuracy. Not a high B.C. bullet, may not use it.


So far, seems WC872 and US869 with 140 NAB/VLD's at 3,200+, 120 mono's, (TTSX/E-Tips) at 3,450 are best performers at half MOA. You add the 139 Scenar over 79 gr. n-570 at 3,300+ to the half MOA club. 139 Scenars also shoot good with 869 and 872.

I've yet to try 120 mono's over n-570. I'm thinking n-570 may outperform 869 and 872, at least QL thinks so. Fast doesn't mean accurate. Maybe I'll get a final combo before the barrel is toast... cry

At 500 rounds, maybe getting close to half way. I'll shoot it as long it'll go half MOA, regardless what the Hawkeye shows.
