Thread: Range day

Day at the range sighting in the new Bushnell elite happy with the end result for hunting rounds will load some more 180 sst with 2206h and 170fn with 2208

Greetings @scotty,
Looks like you are looking for two loads to shoot to the same point of impact, bush and open country perhaps? Care to share?

Bulldozer looks great.possibly find 180 rn Hornady...they awesome projectiles.

@grandpamac yea trying to get 2 or 3 different loads but not to have same poi . Happy to have a bush load at minute of deer at 100yds and have a load 2 or 3 inches high at 100yds . Dumped some more powder in and pulled the projectiles out closer to the lands today to try get the groups tighter . Will also try some 125 sst I loaded today and will get some 150s to try

@ Mickey Duck I have an 8mm for the real thick stuff

Greetings again @scotty,
I went down this road back in the 1970's. At the time I was rather rifle poor with one .308 rifle. I started using 180 grain spire point and flat point projectiles. I found that about 2 grains extra of IMR4064 powder raised the point of impact 2 inches at 100 yards which I think is what you are after. The fly in the ointment was that the flat point projectile shot to one side or the other and there was no way of adjusting for this. Scopes of the day were not the easy dial ones we have today. I fiddled with this for quite a bit so will dig out my notes and targets and report back in a day or two.
Regards Grandpamac.

cheers for that i found the 2208 (4064 equivalent ) worked well behind the flat point 170s but the 2206h was better behind the 180s (10mm lower but a better group)the scope dials so thinking i will set it at zero for the bush round and if i have to dial it for other loads i can.......or the other way around . the rifle is a ruger 1:10 twist , son in law had his ladyshaver 1:9.125 twist (according to wiki) and couldnt get 180s to group at all (reloads or corelokts) he did manage acceptable bush hunting results with 150s and 170s, which seems to be in line with something i read somewhere about 150-175 being the sweet spot for bullet weight for his setup

Greetings @scotty and all,
Looking back in my records I see that my first attempts at multi loading were trying to develop a hare load that would shoot close to the same point of impact as my 180 grain flat nose projectile. The light loads with 100 and 110 grain varmint projectiles shot up to 300 mm higher than the hunting loads. My first .223 was then purchased and that was the end of that. A bit later I had changed to a 150 grain Norma projectile for the main loads which was zeroed at 200 yards. We shot our target comps at 100 and 200 yards in those days so a load that shot to point of aim at 100 was needed. The standard load was 47 grains of IMR4064 with the hunting projectile and 45 grains of IMR4895 with some salvaged .30-06 150 grain military projectiles shot to the same 200 yard zero. 43 grains brought that down to dead on at 100 yards. An attempt was made next to get the 130 grain Speer HP to match the 150 grain point of impact. I could match it for height but it shot left. Another good idea down the drain.
About 4 years ago I did some testing of the Speer 125 grain TNT together with the 150 and 165 grain interlocks and 5 different powders, The aim was to see how different the velocities were with the various powders and how good the load data was. The test loads were shot in my .308 with a 20" barrel and suppressor at 60 metres. The powders were IMR8208, AR2206 and AR2206H for the 125 grain with IMR 8208 replaced with IMR4064 and AR2208 with the heavier projectiles. Only one charge weight for each projectile. the findings were that accuracy improved as the projectile weight increased with both the 125 grain and 165 grain projectiles shooting slightly to the right of the 150 grain especially the 165 grain.
More later.
