So i have some reloading supplies That were handed down. So i am curious if anyone has experience with this?
I normally shoot 150 grain bullets would dropping to 125 throw my sights off drastically. I know there is alot of science behind it but im looking for general answers @100yds maybe 300 yds would be max but just curious
I only ask bc i have enough bullets to finish the brass i have lying around in 125gr but not in 150
TIA
One way to find out. Way too many variables to give a definitive answer, but in all likelihood you would need to adjust. It’s really easy to adjust optics. When shooting the same brand and same type of factory load but from a different lot number I’ll recheck zero and often need to adjust a click or two.
At 100yds… your POI shouldn’t be wildly off.
The Increased velocity helps… however, the drift at 300yds might be frustrating, depending on the BC differences between your 2 different bullets
Personally, I would give it a try. You might really enjoy the results. Lighter recoil …
Im gonna try it i mean its not a lot but i do t wanna waste the supplies i was given.
But thank you for your input! I appreciate it im still pretty new to reloading. I figured about the same thing but just wanted to get other’s opinion
Generally I tend towards heavier bullets, like 180 grain in 308, 140 grain in 6.5, and 115 grain in 6.8 SPC.
BUT you have to accept progress where it occurs.
About 6 months ago I had some minor question about whether the scope on my oldest Palmetto State 308 upper (20" barrel ) was correctly centered Left Right.
I had some bullets with the 110 grain Hornady GMX.
My first shot at 400 yards, the steel target dropped.
Only way that could happen is if it was down to its last strand and the 110 grain bullet found it.
Well unless it was a UFO or something.
Anyway, I was satisfied that the rifle was centered.
In 6.5 Creedmoor I’ve been loading a lot of 140 grain bullets.
But the best shooting I’ve done was, 12/12 using 100 grain Barnes, on the steel target at 400 yards.
Of course I also don’t shoot as many of the heavy bullets because they tend to be expensive.
If you’re talking about 300 Blackout, I find that shooting 300 Blackout at 300 yards, has about as much bullet drop as a 308 at 400 yards.
Every rifle is unique, so YMMV. Generally yes, you will see significant POI shift going from a 150 gr to a 125 grain bullet. At the same time, a 2" shift at 100 yards would be a 6" shift at 300, and maybe that is not an issue for the shooting you do.
You could simply record the adjustment required to zero with the 125gr loads and then set it back to the 150gr zero as needed.
