Surprising ES/SD with Leverevolution - Dt219 - 12-24-2020
Is lever ok to use with 90-100gr bullets ? I know people have been using it in 6arc claiming great results. Surely somebody on here has tried it Chime in please

My SD with my pet load is 7 FPS. Lever is a great powder for the Grendel, my go to. One word of caution, the 32.5 max from the manual is a load I believe your referring to from the Grendel manual. Most of those loads are done by fellas like me in their garage, the arent tested for pressure. Im even in that manual, that means its not a manual pardner. Be careful.

Glad you brought that up. I was looking at some other data yesterday, trying to remember were I got that from. Went back and edited that portion of the data to be more precise.
At the time I wasnt worried so much because I was using a bolt gun and figured the data was from an AR.
Anyway, good catch and thanks for the heads up.

No signs of pressure noted and all 4 of the last single shots went into a 1 MOA group!
Are those normal numbers for Leverevolution?
Ok so what is a realistic min/max charge for LVR. I am going to load for a bolt gun (Howa). If I were to follow Harpoon1s data then I would say that 30-32.5gr is a safe range to use for LVR?
I am going to be loading the 123gr Hornady HPBT in Lapua cases w/Rem 7 1/2 primers.

I would also add, the max load in the Grendel Reloading Handbook had a reported COAL of 2.275
The data I generated was with a COAL or 2.366
I have already loaded up 3 rounds each at 32.8 and 33.1, weather permitting, I intend to light them off tomorrow. Since there was no pressure signs with the last four shots and their POI was virtually identical to the 3 shot 32.5 group, I have high hopes of finding something usable around there.

That area looks like a good place to try. I did notice your COL was longer than book COL. My powder order hasn't even shipped yet so it will be a while before I can do any testing.

I have been testing and using this powder in the 6.5 G for some time now. Think I was the second person to try it besides Nimrod he was testing it before me.It has always given me low ES/SD numbers. Velocity is very much in line my load of 31.8grs with a 120gr BTHP is running just a hair over 2600fps in a 20" BHW barrel AR. 123gr SSTs 2570fps with 32grs.

Anyone come across any pressure data with LVR in a Bolt action Grendel yet? 129 grain projectiles interest me most here, specifically the Hornady 129 gr SP flat base.

Ive never come across any manufacturers Grendel bolt gun data. Ive changed my approach since posting this OP data several years ago. I dont push it like I used to! The Hornady guys have convinced me there is really no reliable way to measure pressure without the proper equipment. Several times in the developmental stage working up loads/data for the 6 ARC, they thought everything was fine out in the field. I.e. no visible signs of pressure, only to find out back in the lab they were substantially over 62,000 PSI. So, I just use the max gas gun data now in the bolt guns, maybe go up 1% more. If I need/want more performance, Ill just use the Creedmoor now. Its just as lightweight as the Mini Howas anyway.
The Hornady book shows 2300 fps/ 18 barrel with 31.7 of CFE223 as max with their 129 projectiles. CFE and LVR are pretty close in burn rate and Ive never had any issues substituting one for the other in the Grendel.

Has anybody used leverevolution for 100-110 gr monolithic bullets?
Surprising ES/SD with Leverevolution - stonehog - 11-15-2023
I did a few ladders with LVR and went from 30.5 to 31.5 and was getting up to 2560fps with Sierra Pro Hunter 120s, slightly less with 120 Speer Gold Dots, and just over 2500 with the 130 Sierra TGKs. No real pressure signals on the brass/primers. Another high velocity powder I'm having good luck with is the Shooters World Match Rifle. I laddered up to 31.4 with 18" velocities over 2600 in 120gr bullets. Sweet spot was 30.4-31grs.
