OK Guys - Skool me on heavies for my 30-06

What are the advantages with running a heavier bullet, say 210 gr plus bullet in my 30-06? 26" barrel, 1in10 twist, min SAAMI chamber. Currently running 168SMK, grouping well below MOA currently.



Thanks.

The 210 will retain velocity for longer distances.
The 210 will have less wind drift as well.
The 210 will have more impact energy at distance.

With a 208 AMax or 210 Berger you will be able to make about 2800 fps via RL22 and a 26" bbl. VV N560 and Norma MRP should get you there too.

The advantages of that over a 168 at say 2900-3000 fps are no mystery, it's just what Jeff said. A quick check via JBM will quantify the ballistic advantages.

The key to maximizing the 30-06 with the heavies is getting the right powder under them to yield the potential velocities that the 30-06 case volume can produce.

The 168 gr school of thought generally calls for medium powders like 4350, 4895, RL15, etc. When you step up to 200+ gr bullets you need to move up to a slower powder and fill up the case to get the most out of the chambering.

When I read the OP first post it was MontanaMarine that came to mind. I have shot beside his 30-06 and know what he states about it is gospel. I was hoping he would see this post and chime in.

Jeff, I had a feeling.......grin.

I've never shot a 168 in my 30-06 so I couldn't give a comparison to a 200+ in field shooting.

I have shot the following in the 30-06 with very good accuracy to 1500 yards or so, and even stretched it to a mile in good conditions.

208 AMax - 2800 fps (26" bbl)
208 AMax - 2720 fps (22" bbl)
210 Berger - 2800 fps (26" bbl)
220 SMK - 2750 fps (26" bbl)
240 SMK - 2620 fps (26" bbl)

RL22 was the propellant in all of these, and bullets moly'd.

Recently I've been shooting the moly'd 208 AMax over RL17, getting 2740 fps from 22" bbl at 70F.

Anyway, these are a few bullets that have really worked well for me inthe 30-06, to distances well beyond 1000 yards.

The Berger 215 should really do well too. I'd guess it can run at least as fast as the 208, maybe even a little bit faster given the bearing surface. Then there's the Berger 230, I'd guess 2650-2700 fps from a 26" bbl.

So many bullets, so little time........grin

If you are able to stretch your rifle to 1000 and beyond on a regular basis, try shooting a few of the heavies beside the 168, and the difference will be very evident, especially if you have some wind. If you seldom get past 600 yards or so, the beauty of the heavies will probably not be fully appreciated.

A 210gr Silvertip will plow a moose. DEEP penetration.

Thanks for the info guys. Are there any aspects of the chamber (throat, etc) that could be a limiting factor and I need to be aware of when I start looking into the 200+ gr bullets?

MontanaMarine, you guessed it - I am wanting to stretch it out there. And yes, currently using H4350. Got both the RL17 and 22 so we are GTG there.
