6.5 Grendel and H335?

I ran H335 with 107 grain bullets. Didn’t have great results.

don’t overlook leverevolution for the 120 class bullets.

Anyone load this cartridge with H335 and a 120 or 123 grain bullet? I am about to start fooling with this cartridge (Hornady Black shoots very well for me) and I have a pound of TAC to try and scored a pound of H335. The goal is a hunting load with 123 grain SSTs for long range deer, out to 300 yards. The thing that has me a little mogadored is that the Hornady data indicates a max load for 120/123 grain bullets that is way below the Hodgdon data for the same bullet weight. I am really looking for velocity here, but I also do not want to blow up the gun. What gives?

I dont know, but i would start at the low or middle of the low end and work up from there.

I see it at midway quite often. Its popular enough to be out there, but doesnt sell very fast.

H335 is my go-to powder for the 6.5Grendel.
Forget the Hornady data. Hodgdons data much closer matches my experience.
My H322 must be a “fast” lot# as I ran high on pressures before velocities matched predictions.
Good results w/#335 from 90to 123gr.

IMR8208. 28.0 grains. 123 grain Hornady projectile. Done.

I use H335 for 100 grain Ballistic Tip bullets for one of my CZ Grendels. With that particular rifle it’s sub-MOA groups.

8208 is king in my book, but forget Finding it.

the lever powder has been impressive and there is lots of discussion about it on the net.

The last tests I ran were leverevolution 30-31.5 grains with a 124 gr eldm at mag length in a gas gun. I was getting up to 2536 fps and sub MOA accuracy. It’s also easy to find.

only downside I see is temp stability.

These.

8208 and the Grendel case are a match ordained by the Gods. As ideal as it gets - great precision and consistency, and if it fits, it ships - I can’t get enough into the case to create excessive pressure.

I’ve bought two 8lber’s of 8208 in the last ~8mos. Just like Varget and H4350; just gotta be watching (no, I’m not running bots to find it).

TAC also works well with the 120 gr. Sierra SP. I have less pressure spike with it over 8208 in my 20" Grendel.

I don't have any of that Powder, but I have A LOT of H335.
Got a 15" Bullberry barrel ordered

A 15” Grendel is a great answer to a lot of questions!

My new Grendel upper is a 20". I shoot lots of 120 Hornady ELDM through it. I have used both Benchmark and H335. I like Benchmark a little bit better, but H335 is a great powder in my book and I too have a LOT of it. When I run out of Benchmark I'll work up a good load with H335 rather than buying more Benchmark at today's prices.
Keep trying, I have not doubt you will find a very good load with your H335.

Im with @Varminterror
8208 is a great powder for a Grendel, doesnt matter if its 6.5, 6, or 22. It just works. H4895 and Benchmark is solid too. Pretty much anything in the burn rate from Benchmark thru H4895 is a candidate, with some powders working better than others.

I never use Hornady's data, ever. Ive found that its too far under what the powder manufacturers recommend. So I start about 1/2 way up the powder manufacturers load range to see what I can see. If Im trying something that Im unsure if its going to work, I generally just pick a mid range load and shoot 3 so Im not wasting alot of time and components. If it shows some promise, Ill investigate further. If not? I wasted 3 primers, 3 bullets and minimal powder. Nothing ventured, nothing gained.
