Does anyone shoot 140's in their bolt Grendel? - BLUESGUNNER - 04-03-2020
I was thinking of trying a VLD 140 in my bolt Grendel. Most of my reloading books stop at 130 gr. Is anyone doing this now?

Second is a member who has experimented with 140 grain bullets in his bolt action. You can use the google custom search feature to find numerous threads on reloading 140 grain and heavier bullets in the 6.5 Grendel. Here is a link to Seconds most recent thread.

Speer has load data online for their 140 grain hot core in 6.5 Grendel. Link to Speer 140 grain data.

IIRC there is also some data in the Grendel reloading books for 140s, for AR but you will get good brass life with the AR loads in a boltaction

On YouTube Jonny's reloading he did a test with Hornady 140 HP match in an AR and found that it was probably the most accurate loads and bullet he has found. Might give it a look see.

I played with some Berger 140 Hybrids and some 147 ELDs a few years ago. If I remember correctly, I think was able to get them up to somewhere around 2440 and 2360 FPS with my Howas 20 barrel. I THINK I was using AR Comp, but it might have been H4895. Any of the other popular Grendel powders are either too fast-burning for the heavies(like 8208), not dense enough to get enough in the case(Varget), or temperature-sensitive ball powders that I dont even want to mess with(CFE,LVR). The 140s were very accurate. And if you plug them into a ballistic calculator, I believe they were catching 123s(at 2620 from the same rifle) in velocity by either 600 or 800 yards. If you want to take your Grendel out to very long range, it might be worth trying.
Shortly after, we had a couple kids. My shooting has mostly migrated to pellet guns since then for their ease and lack of time expenditure, or else I might still be playing with the 140s. I think 147s really are too much for the Grendel, especially since my Litz book shows their BC dropping quite a bit more than many other bullets as the velocity decreases.
The other bullet I thought was worth more time was the 130 RDF. I was able to get them to a bit over 2500 FPS, but never found an accurate load. Always wondered if their listed BC would prove true...
As always, you should work up carefully in your own rifle, watching for pressure signs and using a chronograph.

I have thought about getting the 140 gold dots to work with in my CZ grendel.
With the heavy's say 127 are more I would use h4895 powder.

if i recall the berger reloading manual has some loads listed for the 140s. Lyman published a book on accuracy reloading, which had an article from Dave Emory, the head ballistician at Hornady for many a year. if i recall he recommended a gyro factor of 2 or above. a Grendel won't get there with 140s. 130s is about max. that is with a 1-8 twist. if you want to go 1-7 or so you should be good to go. notice the 300 BLK has a 1-7 twist due to the fact that it's trying to fling 220-230 @<1100 fps. of course long heavy bullets can be shot with gyro <2 but the article was about accuracy, and long range accuracy. notice the 300PRC has, if i recall, a 1-8 spec'd twist to deal with those 220-230 match bullets. it's the length of the bullet vs it's diameter that is the primary driver for what twist rate you need for the bullet for best accuracy. you gotta reach a certain rpm. but twist rate affects that to a much higher degree than velocity. you gotta add a LOT of fps to get to the same rpm as a 1" change in twist rates. so at 3000 fps or so it takes a 8" twist in the 300PRC but at <1100 fps in the 300BLK it takes a 1-7" twist for those same long for caliber bullets. so a 1" twist change makes up for 2000 fps difference in this example.
Hornady's online ballistics 4DOF and Bergers twist rate calculator will give you gyro numbers. the heavy for caliber vld type bullets will retain more velocity at very long distances, in general, but keeping the gyro at 2.0 or higher at launch may give you tighter groups. a miss with a faster bullet is less effective than a hit with a slower bullet.... just saying.... my tightest groups in 308 and 30-06 with 1-10 twists for both have been with 190gr. SMKs. i've tried the 220-230s since there's published load data, primarily in the 30-06 but the tighter groups were with the 190s. when i went to the Hornady 4DOF calculator... hmmm... 190s with a 1-10 twist.. gyro ~2. 225s with a 1-10 twist, gyro < 1.3 if i recall.... hmmm.... tightest group in my 308 was with 190s. so with my Grendel 1-8 twist i'm shooting up to the 130s but have decided not to pursue the heavier bullets. my very limited experience and what i've read seem to indicate that i'll expect tighter groups at 130gr. and below. ymmv of course since each barrel is unique. and if your rifle shoots under 1 MOA it's very difficult to get enough statistical data at close ranges. shoot >= 300yards on calm days, for groups. and at least 5 groups of 5 to start to see statistical differences. and if all your trying to do is to hit a 1/2m gong @ 400m then it probably won't matter at all what bullet you use...

As tdbru states above, I'm shooting only up to 130gr and they are the Berger 130 AR Hybrids. Very accurate in my 1-8 twist barrels, (AR & Bolt). Remember that VLD bullets also take up more case room and the 130 Berger Hybrids really limit my MV's using temp-stable powders. (I can get them up there using cfe223), but I want a powder that is better temp stable year round for my shooting. Anything greater than 130 gr really limits my velocities on pills to 2175 to 2275 fps in accuracy nodes in rounds I can use in both my bolt and AR and these are compressed or near compressed with Varget/8208xbr, etc.
I have H4895 but no data on heavier bullets like my 130 Bergers. Blaster? Any help on this. (Hijack not intentional).

custom competition 140 grain with N140. Was not really chasing groups, but it worked really well and gave me around 700m/sec. 100m group was not that impressive, but no problem hitting 12 cm plate at 500 meters.
Just used it because it was the cheapest bullets i had and wanted to fireform cases (half the price compared to Eld-M 147). Swedish prices are weird.

Lots of great info. Thank you

140sst and 143eldx are some of the most accurate loads i have in my gas gun
