Very nice. To be honest, I always thought of H335 as a powder for larger calibers and cases. I've pretty much stuck with Varget and H4895 for my .223 target loads with heavier bullets. Still, I do ahve a few pounds of H335 in the locker if you care to share your load here or via PM. Thanks for the response.It would be a sweet rifle to have. Im impressed with my 110 Varment in .223. It's very accurate with the right load. Center bottom group. With RMR'S 69 grain target bullets H335 powder. 100 yards.

Oh trust me, I've lost a few nights sleep over the custom build thing already. I've been looking at Savage (and bighorn) actions as well as prefit barrels over at Nothland Shooters supply on /off for some time now. Lots of options . Particularly with barrels. ( Assuming inventory is not depleted.) Building would be fun for sure. Still, it's hard to beat what the precision elite offers for $1800 ish. I certainly couldn't build it for that with an MDT chassis. ( Truth be told, I actually preffer a quality tac/target stock over a chassis for most purposes anway.) This thread is really just part of a decision making process for me. Currently leaning towards the Elite but......It’s nice. But most of us prefer to build our OWN “Precision Elite”. I wanted another Chassis, and prefer building/modifying my own firearms. But if you dig it and it’s calling to ya, go for it.![]()

For the 69's. 23 grains H335 at a COAL of 2.270. I find both of my Savage .223 like H335 the best. Followed by TAC.Oh trust me, I've lost a few nights sleep over the custom build thing already.

p.s. If you have any suggestions for sources/specs , feel free to pass them along. I'm listening.
I was going to the range tomorrow. I'll whip up some of these for a test run before I pack up. Thanks for sharing!For the 69's. 23 grains H335 at a COAL of 2.270. I find both of my Savage .223 like H335 the best. Followed by TAC.
So I did get to build and try 10 of these out of the LRPV this week at the end of my range session. I have to say, that they grouped very well. I got side tracked and didn't actually measure the group but I had 4 rounds go into a nickle sized group ( and one flyer which was me). Velocity out of the 26" barrel was pretty fast at an avg of 2943.7 fps ( per my C1 ). These certainly warrent another (and more serious) test with various seating depths.

Yes, I agree with all said. Still getting to know this rifle. The learning process is where the fun is for me.Tacoma,
I find that it takes me at least a session or maybe two to get the feel of a new rifle. You will see improvement in accuracy when you get some trigger time.
If you aren't used to shooting a HS Precision stock with a long barrel, you might have to experiment with your shooting position a bit and also the placement of the front and rear rests.
Also, when I started to shoot target rifles, I had realized that I needed to aim more precisely. With rifles that can't put bullets in the same holes you can get careless when you aim.
A LRPV can shoot very accurately, but only when the shooter aims very precisely.
I find that with a .223 that is capable of 1/4 MOA like a LRPV, having the aim point off 1/2 the width of a target reticle can cause movement of about 0.1 inch of POI variation at 100 yards.
I had to shoot my new Shilen barrel for a month before I figured that out.
Oh.. well, yeah, I was referring to you. I was asking you. But no man, not what you think. Wasn’t looking to get a rise out of you. It’s one thing I’m not understanding the point of. I tried searching a couple times and what I just said in that last post is all I could find. Scientific measuring tools that obviously none of have access to. LOL! Anywho.., I’ve been stumped on this for years. I’m sorry it sounded the way you took it. My bad. I just didn’t quote you because I thought the question was obvious.Dave, you are probably referring to me, since I have been a proponent of matching barrel exit time to Optimum Bullet time for many years and was far along that path when I posted on the Savageshooters forum.
I almost bet your post # 17 was designed just to get a rise out of me.
Optimum Bullet Time isn't magic, it is physics (and since my undergraduate degree is in physics), it sort of came naturally to me.
Unfortunately, many shooters don't measure all their groups and they judge their accuracy only their very best groups.
For them, it would be a waste of time. Most likely, they don't load for accuracy anyway.
And it takes some degree of analysis of results to see what really works, so not everyone will be interested.
But for those who really want to reduce their group sizes consistently, it can be one of the final steps along the path to being as good as they can shoot.
I have loaded over 82,000 rounds for multiple rifles and, as most of you know, I measure most of my 5-round groups. By last count, I have over 14,000 5-round groups recorded. My data shows that loading for the OBT for a barrel improves its accuracy,
For those of us who use QuickLOAD, that tool provides the barrel exit time of the bullet for each load you calculate.
I believe the other load calculation tool also provides exit time, but I have never used it and can't say for sure.
If you match the barrel exit time for each particular load to the Optimum Bullet Time (OBT) for your particular barrel length and type of steel, you'll be close to the load that reduces the barrel harmonics to the minimum. That give the last bit of help to improve your accuracy.
Caliber doesn't matter because the reflection moves through the steel, not the bore.
Exit time for each load varies with the type of steel, length of the barrel (bolt to crown), powder, charge, seating depth and trim length.
I've been using that technique since 2014 and have documented my improvements as I honed my technique.
I can find the sweet spot for a new barrel within a single range session.
I have plenty of data to show it works to improve accuracy for about 10 rifle-barrel combinations that are accurate enough to bother with it.
The difference with having the OBT with the reflection at the muzzle instead of at the chamber is about 0.090 difference in group size.
I admit that if you can't shoot groups consistently under 0.500, you probably won't see much of a difference, because your 'shooter induced variations' will bias your results and make it almost impossible to notice a difference.
For a 24 inch barrel, it takes only 0.099 to 0.105 msec for the reflection to get from the chamber to the muzzle depending on the steel. Then the shock wave reflects and goes back towards the chamber completing the first reflection.
It normally takes 1.2 to 1.3 msec. for the reflection to get back to the chamber (best for minimizing muzzle harmonics) in most 24-inch barrels at the 12th reflection (usually what will keep the load under Pmax for heavier bullets).
For my .223 barrels, I generally use the 12th reflection for bullets over 69 grains and the 10th reflection for lighter bullets.
For my 6.5mm CM barrels, the 10th reflection is out of the question because it generally produces results over Pmax.
Actually, for the heavier bullets, I have flirted with the 14th reflection, but, so far, I find the 12th a bit more accurate for my barrels.
OBT for 24-inch barrels by type of barrel steel:
Pre-war steel (18.916 fps) - 1.269 msec.
0.3% carbon steel (19,107 fps)- 1.256 msec.
Vanadium (chrome) steel (19,969 fps)- 1.202 msec.
Stainless steel (20,000 fps)- 1.200 msec.
416R Stainless steel (20014 fps) - 1.999 msec.
For those who direct message me and provide their e-mail address, I will e-mail them an Excel spreadsheet to calculate Optimum Bullet Time for their barrels, but they will have to measure the bolt to crown length accurately, and know what kind of steel each barrel is.
Barrels aren't exactly as long as the specified length published, so you have to measure them to know the barrel's true length.
(I have one barrel whose length is 1/2 inch different that its specified length. A few are only 1/8 inch longer.)
