6.5 Creedmoor Starter Loads

[Deermanagement]

Can anyone offer some advice on starter and max loads for the following bullets?

Nosler Accubond 140g
Nosler Accubond 130g
Nosler Ballistic Tip 140g
Hornady V Max 95g

Both Accubonds can comfortably be set 0.020" of the lands, the Ballistic tip will be nearer 0.050" off the lands but not checked the V Max as yet but they'll be some distance off I'm sure.

Rifle and component details :-
6.5 Creedmoor
20" Barrel
RS62 Powder for the Nosler Bullets, Varget for the V Max
Norma Brass
CCI LRP

If necessary I can measure case capacity although never done it before and provide any other data. Just looking for some advice re safe starter loads and suggested max loads, any suggestions appreciated.

I'll send you info from the RS book in the morning
PM me your email

Thx, will appreciate it.

I found RS62 would run at higher pressure's so moved to RS60 and the groups and pressure signs and Es was lower , 1-8 twist fed match primer L/R brass with 140 eld -m 26" bull barrel H-V
if we had imr4350 the world would better place as the two were made for each other lol .

Anyone with start and max loads for similar bullet weights?

Asked Swiss Reload for some data and they were very helpful, coming back the next day with Quickload data.

Just a couple of questions for those of you who have used QL and are know more than me ref reloading.

Firstly, the QL data includes a ±10% powder lot-to-lot burning rate variation using nominal charge. For safety obviously, allowing you to choose a load that still remains within SAAMI or CIP specs should there be such large variation.

My question is firstly, ±10% sounds an awful lot of variation meaning that should this safety margin be used, any powders potential is under utilised. Does QL err a little too much on the side of caution?

Secondly, anyone seen enough to suggest at what point you would expect to start to see signs of pressure below the SAAMI max of 63,000 psi?

I don't think QL is too cautious. Helmut doesn't get to test all the powders all of the time, and some of the lot variations are significant.

I recently did a bulk buy of ADI / Hodgdon powders, with each powder from the same lot, because I was fed up with the variation between lots, particularly with 2209 / H4350.

Last week I used 50 odd rounds from the third batch of 100 reloads, all using the same lot of powder, and the results were consistent with the previous 200, my three zero check shots over the chrono were an average of 3fps off the previous batch of 100. The previous powder lot I used was way slower, 6% on average on the chronograph.

Regarding pressure signs, I started picking up minor ejector stamps at a modelled 62,500psi. This was before I validated the velocity and adjusted the burn rate to reflect what I was getting, after I backed off half a grain. The adjustment to burn rate for the current powder lot is 3.2%.

Just google Nosler reloading it gives loads for 6-5 creedmoor.

Nosler load data does not include any Swiss Reload but Its been suggested to use H4350 load data as a guide for RS62 which I will take into account. It was good of Swiss Reload to come back with the info I asked for although I've asked them to run again with exact case capacities for the Norna cases I'm using and the fact that the loads are for a 20" barrel and not the assumed 600mm.

Afternoon Deermanagemen.
Just a wee word of advice if you go down the small primer route, normal SR primers are not man enough for Creedmoor. I had blowbacks using CCI 400s and it cost over £ 100 for Bergara to repair the bolt even though it was still under warenty. I now use CCI 450 SR magnum primers without any problem.
A little disapointed with Bergara UK as this same scenario has been experienced by several of our cousins across the pond and Bergara USA have responded in a more customer friendly manner and supplied the necessary new parts to carry out repairs. I am led to believe that they have since reworked their B14 bolts and rectified the problem.
Not sure what rifle you use but if it is a B14 be aware of this.

6.5 Creedmoor Load Suggestions

I am about to start reloading for my Remington (Magpul) 6.5 Creedmoor (22 inch barrel 1 in 8 twist). I intend to use once fired Hornady brass, large rifle primers, Honady ELDX 143g bullets and Swiss Reload RS62 powder. I would appreciate any advice from shooters who have reloaded this...

Thanks Bryn, will have a look through the post tomorrow, just off out to check some freshly cut fields. Update on my last entry though, I asked Swiss Reload to run data again using actual case capacities (Norma with large primers) and the fact that I'm loading for a 20" barrel. They came back the next day with all 4 loads run again and an optional powder I asked for on a light load.

Excellent service from them I may say. Next thing is to load some up to try and get an OCW at the range. Norma match 130gr were outstanding and if I can get anywhere near I'll be more than pleased. I'll update the post with some data when I have some initial results.

As a general rule its not advisable to use internet forum data. I've lost count of the number of times I have seen mistakes on powder type or charge weights

Only use published data from manafacturors.

Well.....eventually got around to putting some loads down the barrel. Not a conclusive outcome, mainly because there was not much difference between the POI for the five loads I shot a group for, with the intention of finding an OCW. Coupled with the fact I don't think I made a good job of the range work, with indifferent trigger control, I'm not convinced at the moment.

At the 100m range, the first shot was again from Norma match and if overlaid on the last group shot, it would have made 4 touching shots. First shot from each of the five loads were pretty well spot on, surprisingly so, considering they went from 43.3g of RS62 to 45.5g, working up and checking for pressure as I went. The compressed 45.5g showed no signs of pressure so no issues there.

As far as OCW goes from the groups shot, I'm going to assume somewhere between 43.3g and 44.4g. It'll likely end up with the commonly suggested 44g but I'll try some at extended range when I've chance, decide on a load and try a couple of different seating depth and be done. The QL data supplied by Swiss Reload suggest just over 2700 fps for the 130g Accubonds which I'll chrono if I ever buy on loan one.

Anyhow, have a starter load that has printed just over 1/2 moa with my not so good attempt. I've some loads to develop for both 22/250 and .270 so I'll get some bench practice, especially with the 22/250, to improve technique before spending too much time with the remainder of the Creedmoor loads.

Pic one was the first group shot a couple of weeks ago (Norma Match), and I think I could spend a lot of time trying to match it so I won't try but hopefully end up with a consistent hunting round. The other pics show the first shot (Norma) and the loads 43.3 to 44.4g

Took advantage of light winds yesterday evening, by the time I'd set up, the sun was dipping below the horizon and the 3 intermediate flags I put out had gone limp. I was there to test 3 of the rounds I tested in the tunnel a couple of weeks ago, this time at an extended range. Good job by Swiss Reload, their QL calculation predicted around about 2700 fps for the 20" Sako for what I had loaded and I used this as a basis for the Swarovski Ballistic Calculator which predicted 11 clicks of elevation at 280yds.

So set up, dialed up 11 clicks from my 100yd zero and preceded to test the 3 batches, alternating each load and cooling the barrel between shots. I could make out the shots from the 43.3g loads, seeing each of them on the target through the 3-18x50 Z6i, but I could not see any of the shots from the other two loads. I assumed they were close to target lines (or so I hoped), finished the test and packed up just as it was getting too dark to have continued.

Put things away and went to collect the target. As I drove closer I could see the group from the 43.3g but had to get right up close to see the other 2 groups.

Was I pleased with my evening's work
Worst group 0.678 moa and the best 0.235 moa

Looks like I'll go for around 44.15g which gives a little room for error and will still shoot the same POI. Well done to the helpful Swiss Reload, Swarovski, Sako & LP. One load down, five to go using 3 different rifles
