enfieldsparesPRvi GROM Bullets: Are they any good?
Not the loaded ammunition but the terminal performance of the bullets. I read one review from a professional who thought them superb from roe to wild boar.
Really?
I am thinking specifically of the 185 grain 8mm GROM and using it in a 8x60S at around 2,700fps (or 820m/s in metric) muzzle velocity load.
Ranges from 30 metres out to 150 metres on mainly roe, red and muntjac with maybe one day wild boar.

Some of you that has not seen the Grom bullet or have not used it on game, here is an example of a retrieved .308/170gr Grom bullet. I shot an Eland behind the shoulder at 145 yds and muzzle velocity clocks at 2,500 fps (no major bone was encountered) and retrieved it on the other side, further back on the ribs, just underneath the skin. At that distance the impact velocity was calculated to be 2,177 fps. Its expanded diameter was 11 millimeters or 1.4 times - not bad as it held together, but the mushroom is too small for my liking.
http://forums.accuratereloadin...=965106227#965106227A guy from my parts was shooting them from 30/06 - clean shoot through was the norm, with little or no blood - unless shoulder bones were hit roes went quite some distance (100m).
P.S. "grom" translates as "thunder" from Serbian to English
No expereince with .323" bullets but rather .308".
We'll find out here shortly as I've just received 200 Privi Partisan .308" 11 gramm (169.4 grs.) Grom bullets. We'll be trying them in .30/06 Sprg., .300 Winchester Magnum, 300 Weatherby Magnum & 300 RUM.
They are advertised as a bonded bullet and I do not know what type of core bonding process they use. We tried some factory ammo in .30/06 Sprg. & 300 Win Mag at the very end of last year's season. The factory ammunition was VERY accurate in the rifles (Steyr, Browning, Blaser & Sauer) we tried them in and the one bullet that connected with a medium-sized porker worked excellently.
Both the factory loads & bullets are relatively inexpensive when compared to other "premium" bonded bullet loads & components.
As components - we'll see; give us some time to work up the loads and give 'em a try .....
