Stepped out and tried some VV N570(70.5grns) as per Bergers data with a 140VLD shows great promising as per accuracy and lighting the chrono up a little over 3200fps(3204fps average)! I'm stoked and will verify this load again on the weekend Lord willing!!!! O yeah NO PRESSURE what so ever in the Broughton 26incher!!!!!

That load is a screamer! I imagine RL33 and N570 would be very awesome in the 264 with the heavier bullets. 3200 with the 140's is no joke!

B in TOTALLY freaked me out especially the accuracy! Can't wait to try that load out again. The RL33 suppose to step up velocity as well, which is a good thing being that VV N570 is so expensive and sometimes hard to get......

What size group? VanZwoll clocked 3346 fps with 140gr Hornady with 73gr of H570 which is not made now. What would be the closest powder to the H570?r His group was not that great at 1.2 inches at 100yrds.

.656 FOUR shot group 1st 3 where .558! H570 or H870? If it's H870 I scored on 3lbs of that and is shot better, just ran out of light to chrono....

That load is way to hot in my rifle - caution big time. No criticism of Van Zwoll, as I'm sure he was OK with the stuff he used; it just won't work w/ me and mine.

Everyone needs to use caution when loading hot loads he was using a 26" barrel and has a warning on the article.The H570 was discontinued in the 70's but he did use it.

I found US869 to the powder for my gun. 7828 could match the velocity and accuracy, but case life wasn't good- meaning I had to push it too hard. Found pressure too soon with Rl25 magnum and the other usual suspects. Never seen N570, but would be interested.
And you should be able to hit 3400 with that 30 inch barrel and 130 accubonds. I'm getting 3375 just fine in my 27.5 incher

I am liking those numbers and can hardly wait for the 130's to get here I will be getting a crono soon also.

Here is a decent snap shot of the 264, 26" barrel and a 140 AB and some different powders..

Cartridge : .264 Win. Mag.
Bullet : .264, 140, Nosler AccuBond 39457
Useable Case Capaci: 74.854 grain H2O = 4.860 cm�
Cartridge O.A.L. L6: 3.340 inch = 84.84 mm
Barrel Length : 26.0 inch = 660.4 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 64000 psi, or 441 MPa
or a maximum loading ratio or filling of 110 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
