Your best 6 Creedmore loads

[tbeasley]

Anyone play with 85 Sierra's or 87vmax's?
Gonna start 43.5 RL-17, and 44.0 RL-17 on the 87vmax.
Making twin rifles for predator hunting team. Barrel length at 22".

Have not started loading my 6 Creedmoor yet but was hoping to use Varget as I do in the 22-250 and .308. Has anyone her have any history using Varget/108VLD's/ in the 6 Creedmoor ?

Per Sierra load data, Varget is useable with 107gr - 110gr bullets, but the velocity will be well below the cartridge's potential.

42 grains RL16 behind 105 Hybrid in Hornady brass. I use Federal Gold Medal primers to generate 3,100 FPS in my 26" Bart 7.5 twist.
Very accurate load out to the 1,250 yards I've shot it. Also, not hard on my brass.

Is 42gr a compressed load?

Is 42gr a compressed load?

No.

 

[fatelvis]

42.0 grains of RL16 is showing 99.8% case filled on Quickload, and also showing that it is over max pressure. (64,947 psi. Max pressure is set at 61,989psi.)

I run 42.0gr H4350 with a 105 and a CCI 250... Gets me close to 3200fps in a 22" barrel...I don't know where to send you for specific links to load data on that one...

Quickload is showing this load at 99.4% filled and showing 60,883 psi pressure.

For one, without the parameters of more specific details of my load, I just don't know how you can trust what Quickload tells you. I am telling you that I have fired hundreds of rounds of the load in all kinds of weather conditions without any pressure signs in my rifle. I won't say it will work for you and if you were to take any of the data provided by anyone who posted here without working up then you should not be doing any loading.

39 grains is max load with a Berger 108 in 243. I cannot imagine that a 6 Creedmore would be 42 grains.

I'll update my findings.
Tikka Prefit by Solid Accuracy .At 22" heavy varmint 7.5 twist
Hornady Factory 87vmax was 3198fps average and grouped 1.00" at 165yds

My handloads were;
87 vmax. Jump .020
43.5gr RL-17 @3313 fps (very accurate)
44.0gr RL-17 @ 3380fps (not good)

107 smk .007 jam
41.0 RL16 3050fps (good group)

105vld-h. Jump .020
41.0 RL16 3025fps (poor accuracy)

Shot this cause I wanted velocity
125gr. Hpbt Jam .007.
40.5 RL16 2988fps (ok accuracy)

For what it’s worth, Speer lists 43.4gr of RL16 as max load for their 100 grain bullet.

My hope is to find a load with RL26 in mine. I’ll let y’all know.

So going by these Quickload numbers 42.0grs is 99.4% filled and showing 60,883 psi which is under Max pressure at 61,989psi ?

I agree with shoot4fun, you can't always compare numbers for individual rifles. For example in my 6.5 Creedmoor my best load using 130gr Norma (moly coated) bullets with Lapua SR,S&B primers, and 44.1grs H-4350 produces no pressure signs at all. After shooting over 1,000rds of this load in 200 pieces of brass. Not sure what Quickload would say about pressures for that load? would I recommend it ? ONLY if you start out low and CAREFULLY working your way up, and STOPPING if you have ANY SIGNS of pressure. For my rifle this produces just under 2900fps. Which seems a little slow for the charge, BUT it's SAFE in MY rifle.

Quick-Load is a software simulation tool and I realize that most reloaders realize this. - I hear good and bad things posted about Q/L on here in various forums. - One thing that I rarely hear when criticism takes place is that the Q/L user checked, verified as many variable parameters as possible. - We as handloader's who are seeking accuracy are usually modifying some of the parameters that "may" be taken for granted when using Q/L. - I rarely hear anyone state that they checked their brass case capacity (water over-flow) and adjusted it accordingly or the seating depth of the projectiles. (take for granted that they did all this, or didn't do any of it is unknown as well as that handloader's experience)
- I'll be the first to admit that Q/L is not a perfect world loading solution, I feel that it can be a "more' effective tool if we take the time to verify & set the parameters in the program. - We have variables such as our individual barrels and chambers with differing Lead / Throat dimensions that also become part of the interior ballistics equation as well, also lot to lot variations in powders which we have no control over, but being aware & approaching with judgment are all part of the success or short-coming that go into the process.

Good points Ron, another thing QL does not do, especially in 243 cal is differentiate .236 groove barrels from .237 groove. At times the difference is miniscule, and others it varies greatly from gun to gun.

Have run enough cycles( 10 or more) to see how your Alpha primer pockets are holding up ?

Just going on my 2nd firing, but they should be fine, they're pretty tight right from the beginning.

I do plug in the h2o capacity and length of every cartridge I work with, for more accurate results.
To answer your inquiry about your 6.5 Creed load:
Out of a 24" barrel, it produces 58,951psi pressure (@ 2.8" OAL and NOT jammed), and should get you going 2860fps. The max pressure listed on QL is 63,091psi, so it is not over pressure, and does seem to give a pretty accurate prediction of velocity.

 

[fatelvis]

My best load to date is Lapua LP 308 brass necked down and turned to .014”, Fed210m primers, Berger 105hybrids seated to .015” jump over 40.0 grns RL16. Around 54,000 psi pressure and very accurate!

Thanks fatelvis for the feedback on my load pressure. I do very much appreciate it. Sorry for the delay in not getting back sooner, work has been crazy. Thanks again Larry
