Painless load development (mine)

[huntnful]

H, have you shot a critter with those 109 LRHT’s yet? I’ve got a 7 twist .243 that likes those and I’m curious how they perform on meat.

I haven't yet. I killed a coues deer at 500 yards with the 144LRHT and it performed very well. So I know the bullet style is capable of nice wounds, just don't know if it's optimal for them.

My old load of h4350 and 95 NBT for my 243 shot like shit after bedding, floating the barrel, cutting to 18” and threading (it never shot great, about 2moa at 100 for 10 shots). It was now 2.5” plus at 100. After reading this thread and eliminating most of my case prep methods, I chose two top end loads from hodgdon’s website, one with staball 6.5 one with h414. I loaded 5 of each just to see if they showed promise. Staball shot better than the h4350 load but still 1.5” for 5 shots at 100. H414 put all 5 into .6” at 100. I loaded 10 more and shot the same target, putting all 15 shots into 1.5”. The load clocked 2880. It’s looking plenty good to me, so I’ll load up another batch and shoot some steel.
I appreciate this out look on reloading and avoiding the incremental changes. It was pretty obvious which load was going to shoot looking at the 5 shot groups side by side, only difference being the powder.

as in this case to seat the bullet so the boatail is at the shoulder/neck junction of the case.

@Formidilosus are you referring to the shank being in neck/shoulder junction? or just make sure any portion of the boattail is in the neck/shoulder junction?

ie would you be ok with the redline being at the neck shoulder junction or would you want green?

I’m not Form, but the green is optimal. Other positions can still shoot really good however.

@huntsd I'll disagree with the above, red is optimal.

"Ideal" takes the following into account:
- Doesn't impede on powder capacity or have inconsistent seating resistance from powder compression
- Has enough support of the bullet by the neck
- Keeps bullet bearing surface forward of the "donut area" at neck/shoulder junction. "Donuts" are just a thickening of the neck near the shoulder junction that can occur in brass. Keeping the bearing surface forward of it avoids donuts negatively impacting neck tension consistency or concentricity.

You can have ammo that doesn't align with any of those 3 goals that shoots fantastic, but when people are setting up custom chambers for a given bullet for utmost precision, the above seating depth is typically intended outcome.

I generally set it up so that the green line is barely above the neck/shoulder junction in the case. But it also doesn’t matter really if it is deeper. I generally, again against what most do; do not want the green line very far into the neck of the case.

My primary rifle went to the Smith and wasn't going to be here in time for season, so I picked up another Tikka in 6.5 PRC and added a Trijicon Credo in UM rings. Ordered 100 pcs of Peterson brass and a couple hundred 140 TGK's. Hodgdon's shows 59.9C book max with IMR8133 and a LRP, so I loaded one with 58gr at .010" off the lands and torched it off into the fire pit. Slight ejector mark with a little bit of swipe, loaded 20 at 57gr and went to the range.

What’s your cheek riser in this stock? Like how that looks. Function well for you?

Victor Titan as quoted above. Honestly didn't use it much before swapping that stock out with a custom carbon. Seemed to work fine for it's purpose though.

I have been following this for a year now. I don’t worry about all the fancy gadgets anymore. I use regular full length dies from Hornady. I resize, prime, load, and go shoot.

This was my last group following this method for my 6 ARC.

I’m going to try the method for my first attempt at reloading with my 6arc. If you recall, what were your velocities looking like and your barrel length?

I find action screw torque can have a more drastic effect on groups than messing around with .1 grains of powder. I choose the bullet I want, case and primers and powder. Seat to fit mag, Start near max, shoot three shot groups .5 grains apart, usually 4 or 5 load weights. find the best and start tweaking my action screws...usually gets better.

Got a new barrel on the nrl gun chambered in 6.5x47. A 16# (with bipod) 6.5x47 is kind of cheating.

Loaded up 150 rounds of fresh brass for initial firing and barrel break in. Ran a mandrel through necks to take dings out, no other brass prep (but it’s lapua). Modest loads with 135 CH, 140 hybrid target, 144 lrht, and 140 JLKs ahead of H4350. Intent is to use 144 LRHT once everything is broke in for easy power factor reaching.

Middle group is factory 6 creed from my hunting rifle. Corners are 1” stickers. 135 ch and 140 HT shot about the same. Anyone who says there’s no such thing as inherently accurate cartridges is wrong.

Absolutely beautiful!!

Small modest cartridge at 2700-2900fps paired with a 16lb rifle is going to shoot no matter what the cartridge is. But that thing certainly hammers like a MF.

10.5lb 6.5-7 PRC with 26” CRB hunt barrel. First rounds down the barrel. Just seeing if it prefers a powder.

144 LRHT’s.

Doesn't look like it has a favorite. . Damn son!

Better ocw, ladder, and seating depth test that one to make sure you’re not leaving anything on the table..
