Has anyone done a head to head test on these to and seen how close or different they are. I have some 150 Speers that I have considered expending on this theory but I have about another 15 tests loaded and waiting.
N135 vs imr 4895

I haven't done a head to head yet, but I did compare N135 to AA2495, and both looked very promising. Just working to see if I can tighten up the groups a bit now. I have a ladder loaded up with IMR4895. I'll have to see how it does next time I can get to the range.

Not IMR but H4895
N135 is close in performance to H4895 but not as similar as N140 is to Varget.
The only way to know how IMR4895 stacks up N135 is to test it in your rifle(s).

We all know I'll load it up. It's time to test completion is the real question.
What round are you planning to use it in? My case is 7.62x54r running out of a sportered Mosin Nagant. I was punching sub MOA with the AA2495, and had some horizontal stringing with the N135. I'm working on tightening up the horizontal on the N135 before I make a final judgement on it. I'll also be trying out some N140 in the not too distant future.

308 is the primary consideration but 30-30 is also in question. The speed of these powders seem best in the 150 range as slower would be better as the bullet weights increase.
I'm running Speer Hot Cor 150s in mine, but they're .311 instead of .308. I was working for 2600 or so FPS based on Hornady 11th edition, and forgot to take the chrono out with me. I'm thinking next load out, I'll be double checking Vihta Vuori's data for the round to see if I missed something with the Hornady data. I think Hornady just had too many lawyers involved with the loads they are publishing.

Looking at Lyman and Speer both can be loaded to 45.0 with the 150 btsp. Vv data is lower in the mid 40s. If I were running a test I'd probably run 5 shot groups 5 steps each .3 or .4 grains each. That would be 50 total and a decent range trip.
Your bullets are for 7.7 or 303.
VV data for my round, using a Lapua bullet is 41.7 to 47.1 for N135. Hornady 11th edition is 40.4 to 45.5. The Lyman Historic Military Calibers booklet I have in front of me only has data for N140 as far as VV goes.
You are correct about the 7.7 or .303 bullets. I'm shooting from a 91/30, which has a bore that slugs out to .312. It was the Finn captures, I think M39 if I remember right, that were rechambered to use a .308 bullet. I've also heard of people loading with 123s for the 7.62x39 in them with good results.

I have a friend that uses n135 in his dasher
N135 was very popular for a time as a target powder in the 223 when the AMU was using N135 in their 5.56 V8 loads. That lasted a couple of years and the herd walked over to the next powder du jour.
In the 308 Win, N135 is about as fast as IMR 3031, and so while it makes for an accurate load, it won't be the fastest. I don't have any N135 data in the 308 Win, my advice, look at the published data, and look at IMR 3031, it will be close. And be happy with mid range loads.

I hear you. I’m wanting to try N150 w/185 Hybrids in .308. I have 16lbs of it but haven’t had the time
My .308 seems to prefer N135 to IMR 4895. Pressure signs would show up at pretty much the same velocity between the 2, but N135 is much more accurate for me. GREAT for 150's, 155's(the best for me), and 168's. I feel like 168's are about as heavy as I would go with N135.

I have an accurate 165 grain load of n135 at 39.0 and loaded up a pile. It's definitely not a fast mover.
From the couple pounds I have used in .308, it definitely shines as with 150&155gr! I've had the same experience as you with 168's, accurate, but a little slower than say N140, H4895, AR Comp
