Model 70 Post 64 308 load question

[1942wc58]

Gentlemen'

I have a few model 70 post 64 target rifles that I am going to shoot at some 300-600 yards matches this summer.
I also shoot iron sights, sorry I am old school.

My question is what were some favorite loads that people used for these rifles ?

Thank you in advance

GG

Since you used past tense in your question, here are some older loads used in competitions:

.308 Match Loads Effective out to 200 and 300 Meters
The primary (accuracy) powder charge for each load is noted below. A range of powder grains is included for load tweaking purposes.

168 gr. SMK, 39.0 gr. (37.0 to 39.0 gr.) IMR 3031, LC Match, Fed 210 Primer
168 gr. SMK, 39.0 gr. (38.5 to 40.5 gr.) IMR 4895, LC Match, Fed 210 Primer

.308 Match Loads Effective out to 385 Meters
168 gr. loads above will work like a champ at this distance as long as the wind isn't too bad. The primary (accuracy) powder charge for each load is noted below.

175 gr. SMK, 37.5 gr. IMR 3031, LC Match, Fed 210 Primer
175 gr. SMK, 39.0 gr. IMR 4895, LC Match, Fed 210 Primer

175 gr. SMK, 42.5 gr. Win 748, LC Match, Fed 210 Primer

.308 Match Loads Effective out to 500 Meters
If the wind is blowing like no tomorrow, the 175, 180 and 190 gr. loads will help you stay on target with a minimum of windage adjust required. The primary (accuracy) powder charge for each load is noted below.

175 gr. SMK, 41.0 gr. IMR 4064, LC Match, Fed 210 Primer
180 gr. SMK, 42.0 gr. Win 748, LC Match, Fed 210 Primer

190 gr. SMK, 41.0 gr. Win 748, LC Match, Fed 210 Primer

Long Range .308 Match Loads – Effective past 500 Meters
These loads are on the stout side but, I’ve never had pressure problems while utilizing the Remington 700 Special Purpose or Heavy Varmint barrel rifle. These loads also assume the use of Redding or RCBS full length match dies, Redding Competition Seating Die and a 2.80” overall cartridge length.

175 gr. SMK, 43.4 gr. (42.0 to 43.4 gr.) IMR 4064, Remington or Federal Brass, Fed 210 Primer
175 gr. SMK, 42.0 gr. (40.5 to 42.0 gr.) H-4895, Remington or Federal Brass, Fed 210 Primer
175 gr. SMK, 45.5 gr. (44.0 to 45.5 gr.) Win 748, Remington or Federal Brass, Fed 210 Primer
175 gr. SMK, 43.4 gr. (42.0 to 43.4 gr.) RL 15, Lapua Match Brass, Fed 210 Primer

Just a couple of years ago, my shooting partner and I were challenged to a straight .308 Win. shoot out at 1,000 yards. Scopes obviously for us, prone, no coats or gloves, from bipods. Any safe load and any safe bullet.

We tested for several weeks and arrived at the fact, for our rifles and shooting style, we could standardized on IMR-8208 XBR and the 175 gr. Berger VLD as most consistent, producing small groups.

Of course IMR 3031 is still one of MY favorites...

Many shoot Palma to 1000 yds. with one load:
46.3 gr. (or so) Varget/ Berger, Sierra,155 gr. match bullets jumped about .040"/Lapua small rifle primer brass/any small rifle primer. IMR 4064 works very well but is a bit temp sensitive. Others include Reloader 15, H4895, Benchmark in case is no Varget anywhere to be found. 155 gr. bullets loaded to 2950 - 3000 fps. will remain super-sonic to 1000yds.
This is a load used by many if not most Palma shooters very successfully. You might consider having a look at your throat to make sure there is life left in the barrel. Consider a match barrel when it is affordable. Also consider neck bushing type dies so that you can control neck tension. Most prone NRA matches are single load only so no need to go smaller than .002" neck tension. When seating the bullet, run it in half-way, drop down and rotate the case 1/2 turn and finish seating. You will have much less run-out.
If you have questions, feel from to PM.

Of course IMR 3031 is still one of MY favorites...

Mine too.

My usual bullet is the 168 for my Sako TRG
46.0 gr Varget Has done well in Winchester Brass
42.5 AA 2460 is also very good in my rifle. Excellent metering makes it great for high volume loading.
Safe loads in my rifle YMMV
