Even the Black Hills reman stuff gets expensive after a while. So is there anything out there that offers a lower cost alternative, yet will shoot to a similar POI as say, Hornady 75 gr TAP?

I've heard the Winchester and Federal 62 gr commercial spec loads (not M855) do a decent job. Can anyone confirm or deny this? Again, I just want a cheap practice load that will perform similarly out to around 50 yds so I can do more CQB practice without breaking the bank.

Man, I wish someone was thoughtful enough to provide us with a cheap 75 gr FMJ load for this purpose.

Info per Federal's and Winchester's web sites ballistics info.
Looks close enough to me. Test barrels listed as 24 in.


MV 50 100 50 100 200

FAE 62 gr 3020 -0.2 0 0.7 1.7 0
Win 62 gr 3100 -0.2 0 n/a 1.5 0

Fed 69 SMK 3000 -0.2 0 0.6 1.6 0
Fed 77 SMK 2750 -0.1 0 0.9 2.0 0

____________________________________________________________________

Edit: spacing won't hold (!#$%*). first 50/100 is short zero, last 50/100/200 is 200 yd zero.

Interesting. Thanks.

I suppose the only way to be 100% sure is to just buy a box and see how it shoots in relation to a 75 gr TAP zero. Since it's so cheap, if it doesn't work, there's really no loss.

Maine Cartridge CO..... i've shot their 55 and 62 grain ammo its pretty accurate out of my bushy 20"

alot of people blast the CO, but i haven't had a problem yet JMO
ammunitionstore.com used to sell it but i don't see it on their web page now

The drop is the same for all at that range. It depends where your barrel likes to throw individual loads and how close you need to be to your 75 grain zero.

That's pretty much what I was thinking. It doesn't need to be pinpoint accurate, just accurate enough to put rounds on target of a standard type silhouette target and decently mimick the ballistics of the 75 gr loads. If I could find one that would give decent results from 0-100 yds, I would be a happy camper.

I'm sure that up close, there's not going to be a tremendous difference in POI regardless of the load used. I'll try to experiment and find the one that best matches the 75 gr TAP and go from there. The more realistic the better, but having the same exact POI is not critical. As long as I can keep the change within 2-3", I'll be happy.

CH,
For CQB type training just about any ammo will do - even Wolf. Out to 50y I haven't found that much of a shift in point of impact to worry about. My biggest issue has been with group size (Wolf doesn't hold good groups from my carbines).

I seem to get about the same point of impact in terms of elevation from a variety of 55gr ammo and Black Hills 68gr OTM out to 240 yards.

The problem is, the windage is significantly different, even at 50 yards, for the 68gr vs. the 55gr stuff. It's big enough that I don't feel comfortable about changing from one to the other without rezeroing.

I've been doing a lot of load testing lately. The point of impact will change more than an inch @ 100 yards using the same components with small differences in powder charge. Variations can be larger when using a completely different set of components.

It seems to be a function of barrel harmonics. That means your mileage may vary. It's a lot easier to find a practice load that you want to use and determine the sight changes necessary for your barrel.

The only issue is forgetting to reset the sights for the intended ammo. I like to use a paint marker to indicate zero for the duty round. Makes it easy to know where you are at.
